Product Description


DuraLink 50 Super Adhesion Sealant

Duralink Super Adhesion Sealant

DuraLink 50 is a moisture-curing super-adhesion sealant that cures quickly to form a soft rubber seal. DuraLink is designed for use with many building materials

including: Kynar 500® PVDF coated metals, glass, EIFS, galvanized steel, masonry and many other common building materials. DuraLink is SWR Institute validated for +/-50% joint movement.

DuraLink is an extremely elastic moisture curing sealant designed for use in metal architecture, curtain wall construction and joints subject to movement. DuraLink’s adhesion to difficult surfaces permits its use on anodized metal and coatings such as Kynar 500® PVDF. DuraLink will not stain absorbent stone substrates like limestone or marble. DuraLink’s unique polyether chemistry eliminates out-gassing on green concrete and protects against “sun tanning” or discoloration when exposed to ultraviolet light.
