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 ofresults, and noformulation gives
permission to violate any patent.
