Applications

SM5731 Silicone Sealant is designed for use as a back bedding sealant for drop-in glazing, and as an installation sealant for perimeter and bedding joints. Compatibility testing is mandatory where SM5731 is in direct contact with any other sealant, elastomer, thermal-break compound or architectural paint. When compatibility is verified, it can be used in details such as heel-bead, toe-bead, bedding, cap seal and hidden corner joints. In most cases, no primer (surface conditioner) is required. It is recommended that adhesion test be conducted on all surfaces prior to product acceptance.
