Frequently Asked Questions About SA Sealproof Silicone Sealant
Q: What makes SA Sealproof suitable for curtain wall glazing?
A: Its high joint movement capability (±50%) and low modulus minimize stress on glass and metal, ensuring long-term performance in dynamic building facades.
Q: Can SA Sealproof be used on all types of plastics?
A: It offers primer-less adhesion to many plastics, including acrylic and polycarbonate. However, always test on a small area first to ensure compatibility.
Q: How long does it take for SA Sealproof to fully cure?
A: It takes 10-14 days for a 9mm deep bead to fully cure at 21°C and 50% relative humidity. Cure time can vary based on environmental conditions.
Q: What materials might require a primer before applying SA Sealproof?
A: Materials like concrete, mill finish aluminium, and galvanized steel may require priming due to variable surface characteristics. Always perform a trial application to check adhesion.
Q: Can SA Sealproof be used in submerged applications?
A: No, SA Sealproof is not recommended for locations subject to continuous water immersion.
Q: How do I clean uncured SA Sealproof?
A: Use mineral turpentine on a clean cloth to remove uncured sealant. Ensure proper ventilation during cleanup.
