CRL 321 Acrylic Latex with Silicone is a premium quality acrylic caulk with silicone, featuring outstanding properties including adhesion, weather resistance, low shrinkage, water clean-up, and more. The acrylic base offers outstanding adhesion and resistance to oxidation and ultraviolet rays. The silicone feature improves the flexibility and adhesion to ceramic and glass substrates.
BASIC USES: This Acrylic Latex with Silicone is truly a versatile caulk featuring easy tooling and water clean-up. A special blend of silicone and acrylic latex that provides superior primerless adhesion to building materials such as wood, brick, glass, plastic, vinyl, plaster, drywall, metal, and ceramics. The silicone gives it flexibility, the acrylic promotes long life expectancy. Together they form an excellent sealant that can be used around window and door frames, for siding and trim work, caulking tubs and sink tops, thresholds and baseboards. It may be used to grout marble and ceramic tile, repair mortar joints, and, under controlled conditions, to bed insulating glass units and storm windows.
It can be used for interior or exterior applications since it is odor free and offers superior weatherability. Capable of ±10% joint movement in a well-designed joint. Can be applied at outdoor temperatures as low as 40°F to 120°F (4° to 49°C), and withstands extreme temperatures after full cure from 0°F to 180°F (-17° to 82°C). CRL 321 can be used in areas with high moisture, such as showers, bathrooms, sinks and kitchens, since it is mold and mildew resistant, and is paintable with oil or latex based paint. CRL 321 can be tooled for approximately 30 minutes, and can be painted over after two hours with oil or latex based paints.
