The attached recap shoes the type of asbestos end amount used in our Accessory products, ranging from a lew of 1? to about 10,i. 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 miking 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 K-Spray, Y/atl Texture, Radiant Heat Compound (Santa Ana) and Radiant Hsat Surfacing Compound. All of these formulas require -some fiberous raw material for effective job performance. The Walltex formulas use a very short fibsred asbestos, while the other three products use a , longer fiber (7D and 3Z grades). A substitute raw material may be available1 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 .`Wall Texture and all of the joint r.d finish compounds use a short fiber asbestos. In one product (Topcing Compound) we hove reduced the fiber per centage to less than l, but we do not have any experience on product develo aent with no asbestos fiber.
