Product Description

DuraLink 50 is an extremely elastic moisture curing sealant designed for use in cementitious siding, metal architecture, curtain wall construction and joints

subject to movement. DuraLink 50’s adhesion to difficult surfaces permits its use on anodized metal and coatings such as Kynar 500® PVDF. DuraLink 50 will

not stain absorbent stone substrates like limestone or marble. DuraLink 50’s unique polyether chemistry eliminates out-gassing on green concrete and protects

against “sun tanning" or discoloration when exposed to ultraviolet light.
