DuraSil is a neutral cure (RTV) silicone, adhesive sealant, designed for application on dissimilar materials such as glass, aluminum, steel, copper, masonry and many engineering plastics such as polycarbonate, vinyl (PVC), fiberglass (FRP), asphalt shingles, tile, and acrylic. DuraSil is also well suited for difficult to bond surfaces such as Kynar 500® PVDF and Tedlar® PVF.
ChemLink DuraSil is a neutral-cure RTV silicone adhesive sealant for bonding and sealing dissimilar materials on metal architecture, windows, and curtain walls. The solvent-free formula will not shrink, will not promote corrosion of unprotected metal, and bonds glass, aluminum, copper, masonry, Kynar 500 PVDF, and Tedlar PVF. Typical work includes flashing, copings, glass block, and expansion joints. It is highly elastic, low modulus, and can be applied as low as 15°F.

Is ChemLink DuraSil a neutral-cure RTV silicone?
Yes. ChemLink DuraSil is a neutral-cure RTV silicone adhesive sealant for bonding and sealing dissimilar materials.
Will ChemLink DuraSil promote corrosion of unprotected metal?
No. ChemLink DuraSil is a low-odor, non-corrosive, neutral-cure silicone that will not damage unprotected metals.
Is ChemLink DuraSil for metal architecture, windows, and curtain walls?
Yes. ChemLink recommends ChemLink DuraSil for metal architecture, windows and doors, curtain wall construction, and glass block.
Will ChemLink DuraSil bond glass, copper, and Kynar 500 PVDF?
Yes. ChemLink DuraSil is designed for glass, aluminum, steel, copper, masonry, Kynar 500 PVDF, and Tedlar PVF, plus many engineering plastics.
What service temperature range does ChemLink DuraSil cover?
ChemLink DuraSil is rated from -80°F to 400°F, so it stays elastic in extreme cold and on high-heat metal and roofing work.
When should I use ChemLink DuraSil instead of a ChemLink polyether?
Use ChemLink DuraSil when the spec calls for a silicone, when unprotected metal cannot take a corrosive cure, or when the joint sees high-heat metal or roofing work up to 400°F.
