V, Smith From at A* F, HflffBftlli Antioch. luuter ASBESTOS FIBER 'The attached recap shoes the type of asbestos end amount used in our Accessory products, ranging from a low of I S to about 105. This asbestos fiber is a basic part of each product to provide reinforcement and resistance to cracking of the material on drying. In addition, the asbestos controls other product performance such as mixing water, coverage, and application qualities. If Legislation banning the use of asbestos fiber is restricted to con struction products that are spray-applied, our accessory products affected will be JC-Spray, t'atl Texture, Radiant Heat Compound (Santa Ana) and Radiant Heat Surfacing Compound. All of these formulas require -some fiberous raw material for effective job performance. The Vfalltex formulas use a very short fibsred asbestos, while the other three products use a' , longer fiber (?D and 32 grades). A substitute raw material may be available', such as cotton fiber, which will replace the leng fibered asbestos with no ` loss in the product quality and performance. If asbestos fiber is banned from all of our accessory products; we will be ,faced with a more difficult problem of substitution or reformulation. The Vfall Texture and all of the joint r.d finish compounds use a short fiber asbestos. In one product (Topcing Compound) we have reduced the fiber per centage t o less than l, but we do not have any experience on product develo went with no asbestos fiber.
