RULE 1136 - WOOD PRODUCTS COATINGS
(Adopted September 16, 1983) (Amended August 5, 1988)(Amended May 5, 1989) (Amended March 2, 1990)(Amended June 28, 1990)(Amended November 2, 1990) (Amended December 7, 1990)(Amended August 2, 1991)(Amended April 8, 1994) (Amended August 12, 1994)(Amended September 8, 1995)(Amended June 14, 1996)

(a) Purpose and Applicability
The purpose of Rule 1136 is to reduce volatile organic compounds (VOC) emissions from the application of coatings or strippers to, and surface preparation of, any wood products, including furniture, cabinets, shutters, frames and toys. This rule shall not apply to residential noncommercial operations.

(b) Definitions
For the purposes of this rule, the following definitions shall apply:

  1. AEROSOL COATING PRODUCT means a pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application.
  2. BARRIER COAT - PLASTIC COMPONENTS is a coating applied to simulated wood components made from polypropylene, polystyrene, polyester, polyurethane, and other plastics to improve adhesion of waterborne coatings.
  3. BINDERS are non-volatile polymeric organic materials (resins) which form the surface film in coating applications.
  4. CAPTURE EFFICIENCY, in percent, is the ratio of the weight of the VOC in the effluent stream entering the control device to the weight of VOC emitted from wood product coating operations, both measured simultaneously, and can be calculated by the following equation:

    Capture Efficiency = [Wc/We] x 100
    Where:
              Wc = weight of VOC entering control device
              We = weight of VOC emitted

  5. CLASSIC GUITARS are replicas of guitars that were originally manufactured before 1965 and are manufactured by the same original processes.
  6. CLEAR SEALER is a coating containing binders, but not opaque pigments, which seals the wood product prior to application of the subsequent coatings.
  7. 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.
  8. COATING is a material which is applied to a surface and which forms a film in order to beautify and/or protect such surface.
  9. COMPOSITE WOOD is a manufactured material consisting of tightly compressed wood fibers bonded with resins which includes, but is not limited to, particleboard, fiberboard and hardboard.
  10. COMPOSITE WOOD EDGE FILLER is a material which is applied to the edge of a composite wood product, and whose primary function is to build up, or fill the voids and imperfections on the edge of the composite wood product.
  11. CONTROL DEVICE EFFICIENCY, in percent, is the ratio of the weight of the VOC removed by the control device from the effluent stream entering the control device to the weight of VOC in the effluent stream entering the control device, both measured simultaneously, and can be calculated by the following equation:

    Control Device Efficiency = [(Wc-Wa)/Wc] x 100
    Where:
              Wc = weight of VOC entering control device

  12. CONVENTIONAL AIR SPRAY means a spray coating method in which the coating is atomized by mixing it with compressed air at an air pressure greater than 10 pounds per square inch (gauge) at the point of atomization. Airless and air assisted airless spray technologies are not conventional air spray because the coating is not atomized by mixing it with compressed air. Electrostatic spray technology is also not considered conventional air spray because an electrostatic charge is employed to attract the coating to the workpiece.
  13. CUSTOM REPLICA FURNITURE is new, made-to-order furniture that looks like antique furniture, rather than new furniture. It features detailed wood carvings and bruising of the wood to simulate antique furniture.
  14. DIP COAT is to dip an object into a vat of coating material and drain off any excess coating.

  16. EXEMPT COMPOUNDS - See Rule 102.
  17. EXTREME PERFORMANCE COATING is a two-component high-solids epoxy, urethane or polyester coating which requires the mixing of a resin and a catalyst, and is applied to a wood product to achieve a high gloss and/or high film build coat which cannot be achieved with a low-VOC coating, or to protect the wood product from one or more of the following environmental conditions:

    (A) Repeated scrubbing with industrial grade detergents, cleaners, or abrasive scouring agents; or

    (B) Frequent exposure to water, to outdoor weather, or to ultraviolet radiation.
