LENTEK™ 172 Hybrid Sealant is a Silane-Modified Polyether (known as STPE Polymers)There are two main types of hybrid Sealants: Silane-Modified Polyether (STPE Polymers) and Silane-Modified Polyurethane (SPURS Polymers). The LENTEK 172 is a hybrid chosen for its higher temperature resistance.
Compared to most silicones and polyurethane sealants, LENTEK 172 is both VOC Compliant and meets California Prop 65, and offers a robust adhesion to a broader variation of substrates. Polyurethane sealants tend to bubble more while silicone sealants exhibit more dust and dirt pick-up.
