Description

Flexible MS Polymer Bonding and Sealing Solution for PVC Trim and Exterior Construction

Chem-Set TrimGrip Flex is a professional grade, single component MS polymer adhesive and sealant engineered for bonding and sealing cellular PVC trimboards, CPVC, composites, synthetic wood, metals, and fiberglass. Designed to provide long term flexibility, strong adhesion, and excellent weather resistance, TrimGrip Flex is ideal for applications that require movement accommodation, expansion and contraction control, and a clean, paintable finish.

Unlike fast setting structural adhesives that become rigid, TrimGrip Flex forms a durable elastic bond that resists cracking, splitting, and joint failure. It is ideal for trim installation, gap sealing, nail hole filling, and bonding applications where flexibility is required to handle seasonal movement and thermal cycling.

TrimGrip Flex is the preferred alternative to PVC TrimWelder Fill Flex, delivering faster curing, stronger adhesion, and improved UV and weather resistance in a ready to use cartridge.
