New Bostik Seal N’ Flex Advance

A next generation construction solution

Bostik’s Seal N’ Flex family of expansion joint sealants have been a preferred choice among Australian tradespeople for more than two decades. The newest addition to the Seal N’ Flex product line, Bostik Seal N’ Flex Advance, enhances and adds to the already revered benefits of Bostik’s popular joint sealants. While Seal N’ Flex 1 and Seal N’ Flex FC are based upon traditional polyurethane sealant technology, Seal N’ Flex Advance capitalises on the development of a new hybrid sealant technology commonly referred to as SPUR (Silyl-Terminated Polyurethane). This modern chemistry improves  the weathering characteristics of the traditional PU sealant while removing the isocyanates and solvents. Alongside the significant health and occupational safety benefits, Seal N’ Flex Advance boasts several advantages that will make application easier and faster. Firstly, Advance will extrude smoothly and easily from any hand operated or electric caulking gun. Seal N’ Flex Advance also exhibits greater flow stability in temperature extremes. While polyurethanes experience hardening in excessive cold or softening in the heat, Advance will maintain a more stable gunnable body. It will also adhere to damp surfaces. Finally, the absence of solvent curing agents results in a more consistent curing process throughout the seal, regardless of climate conditions. This means absolutely zero bubbling of the cured seal. Advance exhibits higher mechanical and abrasion resistance than common polyurethanes also. Seal N’ Flex Advance is a step forward in construction sealants and a level above the competition. The enhanced feature set of this powerful sealant makes it the number one choice for expansion joint sealing and will improve the work speed and safety of applicators. Seal N’ Flex Advance is available from March 2019. Ask your local supplier about Seal N’ Flex Advance today.
