When molding a product, the volume of the mold is the basic measurement; the bar chart shows the comparison in weight/volume. SIL-CELL is used in rotation molding; cultured marble; thermo-set castings; syntactic foam; SMC and BMC compounds; auto body putty; sealants and adhesives; patching compounds; FRP spray and hand lay up; tub and shower enclosures; and, explosives. SIL-CELL is available with a variety of proprietary coatings to enhance its performance. MIXING PROCEDURE The use of a low shear, folding type mixer is desirable to minimize particle breakage. When mixing SIL-CELL, it is important that it is thoroughly mixed and "wet out." Technical data shown is considered accurate and reliable. However, there is no guarantee of results, and no formulation gives permission to violate any patent.
