Wood Finishing 101 – Specialty Coatings

Wednesday, July 11th, 2012

“Where do we use these Coatings”

Specialty Coatings:  As the kitchen cabinet industry has grown and evolved over the years, so has the finishing processes. In recent years, there is a much greater demand for “furniture look” finishes. By this, most major manufacturers offer different glaze, distressing, sand through, and crackle lacquer packages, usually at a substantial upcharge.  These offerings can be relatively simple; stain, seal, glaze, and topcoat or extreme: NGR, distress, stain, seal, crackle lacquer, glaze, and topcoat. Obviously, there are many different combinations where these types of products may be used. One other major note: these are all labor intensive and hand done systems.

Fillers are recommended where there is a desire to completely fill the grain of the wood. Clear coatings should not be used for this purpose (with the exception of polyesters) because they simply aren’t designed to perform this job.

Wood Finishing 101 UV Curable Coatings

Where do we use these Coatings

UV Curable Coatings:  These are unique coatings in that they cure when exposed to UV lights. They are generally considered a specialty type of coating which requires very specialized equipment. If they are less than 100% solids, then it is necessary to get all the solvent or water out of the product prior to exposure to the curing lights. Once exposed, cure can be completed in a manner of seconds. The end finish usually is very hard and very durable. They may be found in use on kitchen cabinets, doors, millwork, and paneling.

Wood Finishing 101 – Conversion Varnishes

Tuesday, June 19th, 2012

Conversion Varnish: These products provide outstanding durability and chemical and water resistance. This is why they have virtually taken over the cabinet industry. As mentioned, they are usually catalyzed with a strong acid catalyst which results in a “worklife”. It is recommended that only the amount that will be used in an eight-hour period be catalyzed. Beyond that, excess material should be disposed of or “decatalyzed”. They usually are quite a bit higher in solids content, 30-45% by weight so often the higher cost per gallon is offset by the need for less material. There are limitations and procedures which must be followed. They are not simple products to use and failure to adhere to the proper procedures can result in severe failures. Some of these precautions include: do not let the material, either catalyzed or uncatalyzed, come into contact with any raw iron or aluminum; the acid catalyst is very strong and should be handled accordingly, catalyst ratio must be followed exactly, and worklife limitations of the product need to be observed.

Wood Finishing 101 – Stains

Thursday, June 14th, 2012

Stains-   Most wood is stained prior to clear coating if it’s not going to be painted. Occasionally there are jobs which have a natural finish (no stain) but for the most part, some sort of stain is applied. The end use and appearance will determine the best type of stain to be used.

Non-Grain Raising (NGR) stain: They are usually dyes dissolved in an alcohol, usually ethyl alcohol. They are spray applied only and very fast drying. In most cases, they will be encountered in the furniture industry or cabinet industry. They are usually used to change the color of the wood prior to application of another, type of stain. For example, on maple, a relatively dense wood that where a very dark color is trying to be achieved, an NGR should be applied to get 60-70% of the desired color. After that application, usually a wipe stain is then applied. This accomplishes a couple of things. First, a dark color can be achieved without threat of inadequate adhesion and second, an often desirable appearance with “depth” is evident. They are not used as a stand-alone stain.

Sap stains and equalizing stains: These are dyes stains, again usually in an alcohol, used on only certain portions of a piece of work, typically only to change the color of isolated areas of the substrate. For example, if you had a greenish streak in a piece of maple or poplar, a reddish sap stain might be applied only to that streak. An equalizing stain on the other hand would be applied to everything but that greenish streak. As above, these are used as only a step in the staining process and another type of stain needs to be applied over these. These stains are usually only seen in the furniture industry. 

Dye stains: These are similar to both of the above but are used as the only stain. A typical application might be for window blind slats. They aren’t the best looking stains but depending upon the application and type of wood, could be acceptable. These types of applications are often dip applied and therefore the solvent blend is usually slower than the above stains.

Spray stains (solvent and water): These are blends of colorants in an appropriate base which is usually fairly quick drying. They allow for a quick staining process (higher volumes). Most millwork and door shops use these types of stains. As their description implies, they must be spray applied.

Wipe stains (solvent and water): These are blends of colorants in an appropriate stain base which provides a relatively long “open” time in order to allow for wiping of the stain. They are usually spray applied with a very wet coat. The time allowed before wiping (open time) can vary from just a few seconds to several minutes. They should be allowed to dry completely before applying a seal coat. Most cabinet and furniture manufacturers use these types of stains as they enhance grain definition and provide more “warmth and character” than spray-only stains.

Stain concentrates: These are typically solvent based only. They are mostly straight tint pastes along with a varying amount of stain base (not reducer). The end user will reduce with an appropriate stain reducer (spray type or wiping type) to achieve a desired color strength.

UV stains: These are stains which are used for applications beneath UV curable coatings. They are very unique in regard to stain base and colorants. They are usually highly specialized applications. They are often necessary to insure adequate adhesion and performance of the UV curable clear coats.

Wood Finishing 101

Friday, June 8th, 2012

There are an unlimited number of finishes and systems that can be applied to wood. These cover everything from a simple coat of shellac all the way to multiple step (up to 20-30 steps) furniture finishing. Luckily, in the vast majority of the general finishing industry, it is typically a stain, one or two seal coats and a topcoat.  We will discuss briefly, throughout this series of articles the most common finishes that you can expect to encounter.

         The end use of the product will determine the optimum coating that should be applied.  First of all, there are interior and exterior applications. Each of these have their own set of needs in regard to resistance and durability. For example, a house paint is designed for exposure to the weather and is made to last, hopefully, for several years.  A nitrocellulose lacquer may not last much more than a month if it was used as a house paint. On the flip side, you wouldn’t expect to put a house paint on a kitchen vanity and have it provide the look and appearance that is desired.  For this discussion, we will focus on interior products.

Types of Wood Coatings: 

Stains- NGR’s, sap stains, equalizing stains, dye stains, solvent borne spray stains, solvent borne wiping stains, solvent borne stain concentrates, waterborne spray stains, waterborne wipe stains, UV stains.

Lacquers – By definition, a lacquer is a coating which forms a film as a result of solvent evaporation. These typically have been modified to be precatalyzed nowadays. Lacquer types include: nitrocellulose, acrylic, vinyl, cellulose acetate butyrate (CAB), urethane, and waterborne. Usually, lacquers are a blend of two or more vehicles, i.e. alkyd modified nitrocellulose, acrylic/CAB, etc. Lacquers can be sealers, topcoats or a self-sealing product.

Conversion Varnishes– In the simplest terms, a conversion varnish is an acid catalyzed blend of alkyd and urea resin. However, they are most times modified with other resins to enhance dry times and/or provide better performance. They may be solvent borne or water borne.  They typically provide far better resistance properties than lacquers and thusly ALL major kitchen cabinet manufacturers use these at a minimum (some use UV curable coatings).

Paints-These may be pigmented lacquers (or lacquer hybrids) or conversion varnishes. Primers also follow this same premise.

UV Curable- These may be solvent borne, water borne or 100% solids. They may be spray applied, DRC (direct roll coat), vacuum coated or fancoated. These include stains, sealers, topcoats, fillers, and paint.

Specialty Types- Glazes (wipe and breakaway), crackle lacquer, fillers, and toners.

Labels: Reading the Fine Print

Wednesday, May 16th, 2012

Have you ever tried to read the directions on the back of a product and feel like you need a magnifying glass, despite your 20/20 vision? Forget it if your vision is worse! We are often asked, “Why don’t you have more information on your label on how to use your Stove Bright® Aerosol Paint?” The simple answer to that question is…Real Estate! Or, the lack thereof. As anyone that has used our product knows, there is more to using our paint than just spraying it on and firing up the stove. While our paint is fairly forgiving, there is a process to heat the steel so that it does not expand too quickly, causing the paint to crack or fail during the off-gassing phase. Describing this process requires a lot of information. Here is the process required to set our paint: User Guide.

Nearly any product that you buy ranging from groceries, to appliances, to hygiene products is required to have appropriate warnings about that product. Required warnings on our standard 12oz aerosol can chew up about 50% of the available label space. As product packaging gets smaller, the demand for space for warnings goes up. It becomes increasingly difficult for companies to convey all the information that they would like, especially for a technical product such as our Stove Bright® High Temperature Paint. This is why we provide a user guide on our website.

Regulations also require a certain type size and font. This type size and required space doesn’t decrease with smaller packaging, it remains the same. Therefore directions for product use take the hit. Manufacturers are not trying to test your eyesight; they are simply trying to get you as much information as they can about both the content of the product, and about how to use it. This is a burden for all manufacturers. Take a look at first 2-3 pages of your next purchase of a kitchen appliance or a television and you will see a laundry list of ways NOT to use their product.

We are in the process of making the use of 2 part epoxy adhesive systems much cleaner, faster, efficient, and ergonomic. The use of these adhesive caulking guns will alleviate pain in the hands caused from mixing in bags, increase efficiency because it mixes itself rather than taking 15 minutes or more to mix by hand, and clean up the mess by having an actual tip. Take a look at the pictures and see for yourself!

These cartridges will be available in 5 oz. or 10 oz. fills.

The essentials of exports

Monday, April 16th, 2012

Forrest Paint Company is locally owned and operated in Eugene,Oregon. Since our inception in 1973, all of our manufacturing has taken place here. What some of you may not know is that we also have warehouses across the United States and Canada with product and application experts available in Australia, New Zealand, France, China, and the United Kingdom.  Forrest Paint was even honored to receive the Oregon Exporter of the Year Award in 2005, and the Export Achievement Certificate from the Unites States Department of Commerce in 2011.

I am very privileged to take part in our International Business. Our Export Manager and I work with freight forwarders to obtain the best freight rates and provide all the documentation necessary for Customs clearance. It is truly amazing the differences in export logistics verses domestic logistics. Not only are international shipments subjected to more U.S. regulations, they are also subjected to the regulations of whatever country you are shipping to. Knowing their regulations is imperative in achieving smooth shipments.

With a domestic shipment, about the only thing that can hold up a shipment is weather. With international shipments, one wrong word on a document can cause weeks of delay in Customs, as well as, possible fines. So, being a manufacturer of hazardous goods, knowing where our products are accepted (or not) and what the proper product shipping names are plays a huge role. The good thing is that there is an abundance of freight forwarders that can help with questions, as well as, many different training options. IMDG (International Maritime Dangerous Goods) training programs can now be purchased to receive all online certifications.
