PRODUCTS - HTPROCARBOS lMXSSIOMa A* discussed in Pollution Bullotla dated April 26, 1971* nS Mop 5, 1971* it is likely that our point products will boro to eonforu to loo Ansoloo 8ulo 66 or o modified ver sion of it by the cad of 1972. To assist in evaluating the impact of 8ulo 66 on particular product lines, a copy of 8ulo 66 is attached elans with n brief summery given below. The purpose of Rule 66 is to reduce the mount of A&eSS&tBlSftUK gw*UTM solvent spitted. The definition of a photochealeally reactive solvent is defined in section 66 k. A solvent systea Is conforming if it contains less than the pre scribed SUQtiat Of reactive solvents, Sad non-canfarlnm if it centaina nore than the prescribed amount, aasMIfSSiaiq SOfrllBlS (defined in 66-Id) it is unlawful to so11 pr^use a coating, which contains a non-confoming solvent systen. (66-la, b, and c) for industrial coatinas (all coatings outside the definition in 66-ld)the linitatiens as to the type and amount of solvent allowed depends on whether or not tho coating is host JH$aas&tt r fiAtt wr ffp^m^-tyewsft.im. Tabu x lists 1ST allowsbls sniseions par source (as defined in Section 66 s sad b). A ruling by the Los Angeles Air Pollution Control District hsa defined "heat polymerised" as a process vt)rt cross-linking occurs. Thus, forced solvent evaporation by heating would not bo oenoidsrod heat curing if other reaction takea place during the heating. All industrial seating system would bo in tho solvent evaporation category during tho spraying operation regardless of whether or not the coating is subsequently hast polymerised. Thus, with a conforalng solvent systen, controls asy bo required for tho baking oven exhaust but not for tbo spray booth exhaust.
