Tuf-Link is a water resistant concrete bonding adhesive and admixture. Tuf-Link Bonding Agent can be used interior or exterior, above and below grade. Tuff-Link can be used as a non re-emulsifiable coat-on bonding agent, a primer/Sealer coat, and as an admixture.
TUF-LINK admixture increases the cement’s bonding with the aggregate. This improves the strength, flexibility, durability, and chemical resistance of the finished product. TUF-LINK meets ASTM C932.
Tuf-Link uses a proprietary emulsion copolymer that provides superior water resistance, so much so that is used for underwater applications in swimming pool construction. A big advantage of Tuf-Link as an admixture is it produces an almost buttery like consistency to the cementitious product making application a breeze. Its greater plasticity and elasticity also reduce cracking and improve impact resistance. These characteristics also enhance curing. Most concrete bonding agents use acrylics to provide water resistance, but the acrylic also adds stiffness to the product reducing workability increasing the application time and labor and also reducing penetration into the concrete. Acrylics are also somewhat brittle.
