Chemlink 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. DuraLinks 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.
DuraLinks unique polyether chemistry eliminates out-gassing on green concrete and protects against "sun
tanning" or discoloration when exposed to ultraviolet light.

Not criticisms but observations for what they're worth. Easy purchase but free delivery was slow: October 29 to November 6, 2025. Faster mail service makes this product's market price cost prohibitive on your sight. Time constraints are less a factor for small DYS homeowner projects, but larger project and contractors, it creates an undue consideration. Key and foundational shipping offsets of large big-box stores and online retailers are quantity purchases and 'membership fees,' the latter being the most important key.
Its nothing like what I thought it was but buying and shipping process was smooth.

I spoke with the person in the Technical Support department who listened and understood my complicated circumstances and made the perfect recommendation. I received the product within a couple of days and before the weekend ended, the job was complete and I am very pleased with results. Thank you, Eco Building Products for your support and product recommendation.
The staff gave me good advice on how the products work and which ones to use. And they shipped it here really fast.

Adam B.07-06-25
Packed well, arrived quickly and installed in a cinch. My only recommendation would be to post a picture with actual dimensions of the box for the rough opening and of the outside of the trim. It would help those on a tight a schedule who have to cut the whole before the product arrives. Otherwise great overall experience. I will be purchasing more of these in the future
