The ideal alternative

LENTEK 172™ is the ideal alternative to polyurethane, silicone, solvent-based, and other adhesive/sealant chemistries. It offers a robust adhesion to a broader variation of substrates and is UV and weather-resistant.

LENTEK 172 does not bubble up as much as polyurethane sealants and it exhibits less dust and dirt pick-up than silicone sealants. The hybrid is paintable within 24 hours of application and is non-corrosive, making it the best choice over other sealants.
