Product Identity

D.A.P. Silicone Sealant White 9.8 oz cartridge is a flexible, waterproof sealant designed for windows, doors, siding and trim. It meets ASTM C719 Class 25 and ASTM C920 Class 25 standards for joint movement capability. The product is mildew resistant, mold resistant and weather resistant for exterior and interior use.

Installation Practicality

The cartridge fits standard caulking guns and offers a five minute working time before skinning begins. Full cure requires one day at typical conditions. Surfaces must be clean, dry and free of old sealant for adhesion. The sealant cannot be painted, so masking adjacent areas is essential to avoid visible smears on finished surfaces.

Temperature And Movement Limits

Continuous performance range spans from minus 40 degrees F to 350 degrees F. The Class 25 rating accommodates up to twenty five percent joint movement in extension and compression. It is not intended for structural bonding, below-grade immersion or horizontal traffic surfaces where abrasion resistance is required. California Proposition 65 warning applies.
