Chemlink DuraSil High Performance Sealant
DuraSil™ is a single component neutral cure silicone construction sealant used for a wide range of new construction and renovation applications.
It has outstanding weather resistance and durability in dry, cold or wet conditions. DuraSil is stable to temperatures up to 400° F. DuraSil bonds well to Kynar 500® PVDF coated metal, glass block and many other materials.
DuraSil may be used to seal windows and doors, curtain walls, and in many marine and transportation applications.
DuraSil is a neutral cure (RTV) silicone, adhesive sealant, designed for application on dissimilar materials. Glass, aluminum, steel, copper, 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 develops properties rapidly and is effective in many industrial applications where strength, elasticity, adhesion, and speed of set are required.
