SANTA BARBARA COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 351 - SURFACE COATING OF WOOD PRODUCTS
(Adopted 8/24/1993, Revised 9/21/1995 and 8/20/1998)
This rule applies to the application of coating to, and surface preparation of, wood products.
"Binders" are non-volatile polymeric organic materials (resins) which form the surface film in coating applications.
"Clear Topcoat" is a final coating which contains binders, but not opaque pigments, and is specifically formulated to form a transparent or translucent solid protective film.
"Coating" is a material which is applied to a surface and forms a film in order to beautify and/or protect such surface.
"Detailing or Touch-up Guns" are small air spray equipment, including air brushes, that operate at no greater than 5 CFM air flow and no greater than 50 pounds per square inch gauge (Psig) air pressure as measured at the air inlet and are used to coat small products or portions of products.
"Dip Coat" is to submerse an object in a vat of coating material and drain off any excess coating.
"Electrostatic Application" is charging of atomized paint droplets for deposition by electrostatic attraction.
"Exempt Solvents" means compounds identified as exempt under the definition of "reactive organic compounds," Rule 102.
"Filler" is a preparation used to fill in the cracks, grain, etc. of wood before applying a coating.
"Flow Coat" is to coat an object by pouring a stream of coating over an object and draining off any excess coating.
"Grams of Reactive Organic Compound per Liter of Coating (Pounds of Reactive Organic Compound per Gallon
of Coating), Less Water and Less Exempt Compounds" is the weight of Reactive Organic Compound per combined
volume of Reactive Organic Compound and coating solids and can be calculated by the following equation:
"Grams of Reactive Organic Compound per Liter of Material (Pounds of Reactive Organic Compound per Gallon
of Material)" is the weight of Reactive Organic Compound per volume of material and can be calculated
by the following equation:
"High-Solids Stains" are stains containing more than 1 pound of solids per gallon, and can include wiping stains, glazes, and opaque stains.
"High-Volume Low Pressure (HVLP) Spray" is to spray a coating by means of a gun that operates between 0.1 and 10.0 pounds per square inch gauge (Psig) air pressure.
"Ink" is a fluid that contains dyes and/or colorants and is used to mark, but not to protect surfaces.
"Low-Solids Stains" are stains containing 1 pound or less of solids per gallon.
"Mold-Seal Coating" is the initial coating applied to a new mold or repaired mold to provide a smooth surface which, when coated with a mold release coating, prevents products from sticking to the mold.
"Multi-Colored Coating" is a coating which exhibits more than one color when applied, and which is packaged in a single container and applied in a single coat.
"Pigmented Coatings" are opaque coatings which contain binders and colored pigments which are formulated to hide the wood surface, either as an undercoat or topcoat.
"Repair Coating" is a coating used to recoat portions of a product which has sustained mechanical damage to the coating following normal painting operations.
"Roll Coater" is a series of mechanical rollers that forms a thin coating film on the surface roller, which is applied to a substrate by moving the substrate underneath the roller.
"Sealer" is a coating, containing binders, which seals the wood prior to application of the subsequent coatings.
"Simulated Wood Materials" are materials, such as plastic, glass, metal, etc., that are made to give a wood-like appearance or are processed like a wood product.
"Stencil Coating" is an ink or a pigmented coating which is rolled or brushed onto a template or stamp in order to add identifying letters and/or numbers to wood products.
"Toner" is a wash coat which contains binders and dyes or pigments to add tint to a coated surface.
"Touch-up Coating" is a coating used to cover minor coating imperfections appearing after the main coating operation.
"Transfer Efficiency" is the ratio of the weight of coating solids deposited on an object to the total weight of coating solids used in a coating application step, expressed as a percentage.
"Wash Coat" is a coating that contains no more than 1.0 pound of solids per gallon, which is used to seal wood surfaces, prevent undesired staining, and control penetration.
"Wood Products" are those surface-coated room furnishings which include cabinets (kitchen, bath, and vanity), tables, chairs, beds, sofas, shutters, art objects, and any other coated objects made of solid wood, and/or wood composition, and/or made of simulated wood material used in combination with solid wood or wood composition.
D. Requirement - Reactive Organic Compound Limits
E. Requirement - Transfer Efficiency
A person shall not apply wood products coatings subject to the provisions of this rule unless the coating is applied with properly operating equipment, according to proper operating procedures, and by the use of one of the following methods:
F. Requirement - Prohibition of Specification
No person shall solicit, require for use, or specify the application of a coating on a wood product if such use or application results in a violation of the provisions of this Rule. The prohibition of this Section shall apply to all written or oral contracts under the terms of which any coating which is subject to the provisions of this Rule is to be applied to any wood product at any physical location within the District.
G. Closed Containers
All reactive organic compounds-containing materials, used or unused, including but not limited to surface coatings, thinners, cleanup solvents, or surface preparation materials shall be stored in closed containers and opened only during extraction or introduction of material for mixing, use or storage.
H. Test Methods
(less water and exempt compounds)
