DuraSil is a moisture cure (RTV) silicone, adhesive sealant, designed for application on dissimilar materials such as glass, aluminum, steel, masonry and many engineering plastics such as polycarbonate, vinyl (PVC), fiberglass (FRP) and acrylic. DuraSil is also well suited for difficult to bond surfaces such as Kynar 500® PVDF and Tedlar® PVF.

DuraSil’s low odor, non corrosive, and neutral cure chemistry will not damage unprotected metals. DuraSil is highly elastic and low modulus with mechanical properties capable of low temperature flexibility and 50% joint movement. DuraSil is recommended for metal architecture, windows and doors, curtain wall construction, and glass block.

DuraSil develops properties rapidly and is effective in many industrial applications where strength, elasticity, adhesion and speed of set are required.
