Silicone acrylic sealant, also known as hybrid sealant, is a flexible caulking compound that combines the best qualities of silicone and acrylic. This unique formulation offers the weather resistance of silicone along with the strong adhesion properties of acrylic. It's perfect for a variety of applications, including construction joints, window sealing, roofing gaps, and industrial bonding. This versatile sealant provides UV resistance, flexibility, and durability in extreme temperatures, ranging from -10°C to 70°C. It effectively seals out air, moisture, dust, dirt, insects, and noise.
Weatherproof & UV-Resistant: Can withstand rain, sunlight, and temperature fluctuations.
Strong Adhesion: Bonds well to materials such as concrete, metal, wood, glass, PVC, and ceramics.
Flexible & Crack-Resistant: Maintains elasticity even after curing.
Paintable Surface: Unlike pure silicone, it can be painted over for a seamless finish.
Eco-Friendly Formula: Low in VOCs, making it safe for both indoor and outdoor use.
Seal window and door frames to prevent air and water leaks.
Waterproof roofing joints, expansion joints, and concrete cracks.
Repair PVC pipes, gutters, and metal flashing.
Fix bathtub edges, kitchen countertops, and tile gaps.
Bond decorative moldings, skirting boards, and lightweight materials.
Clean Thoroughly: Remove dust, grease, and debris using a brush or an alcohol wipe.
Dry Completely: Ensure surfaces are dry (moisture content ≤8%).
Prime Porous Materials: Apply a primer on concrete or wood for improved adhesion.
Cut the nozzle diagonally to match the width of the gap (recommended: half the joint size).
Load the sealant tube into a caulking gun.
Hold the gun at a 45° angle and apply steady pressure for a smooth, continuous bead.
Tooling Tip: Smooth the sealant with a wet spatula or your finger immediately after application.
Skin Formation: 20–40 minutes (at 25°C and 50% humidity).
Full Cure: 24–72 hours (depending on thickness and humidity).
Avoid Common Mistakes: Do not apply in rainy or extreme temperatures (below 5°C or above 35°C).
Overfill Deep Gaps: Apply in layers for full adhesion.
Compatibility Check: Test on coated metals or sensitive surfaces before full application.
Cleanup: Use mineral spirits for cleanup before curing; dried sealant will require mechanical removal.
