TremPro 635

Fast-Cure, Low-VOC, High Solids Polyurethane Sealant

TremPro® 635 utilizes a solvent-free technology, which represents technical advances over existing polyurethane systems. In addition, TremPro 635 demonstrates excellent adhesion to a wide variety of substrates, including ferrous, non-ferrous metals, kynar finishes, composite materials and many plastic rubber substrates.

TremPro 635 is a high performance, low-to-medium modulus, onecomponent, gun grade polyurethane sealant. The sealant cures to a flexible rubber when exposed to atmospheric moisture.

Basic Uses
