WEBAC® 4525: water resistant epoxy putty for underwater use

WEBAC® 4525 is a universally applicable putty/adhesive which adheres to almost any substrate – also to damp surfaces. It is among other things suitable for sealing and patching cracks in stoneware pipes. WEBAC® 4525 can be used as adhesive for glass, tiles, ceramics and selected plastics such as PVC. In concrete repair, WEBAC® 4525 can be used on dry, damp and wet substrates. WEBAC® 4525 is also suitable for installing WEBAC® TPE sealing tape when repairing construction joints. WEBAC® 4525 complies with DIN EN 13813.
 

Underwater use: the putty WEBAC® 4525 withstands water

WEBAC® 4525 is a non-drip, universally applicable putty and adhesive with excellent adhesive properties on dry and damp mineral substrates. WEBAC® 4525 cures to form a solid compound of good chemical resistance. The putty WEBAC® 4525 withstands water and can is applicable underwater after mixing. Whirling water or pressurized surface water, e.g. from cracks, must be avoided. 

The workable life of WEBAC® 4525 amounts to approx. 25 minutes (20 °C). WEBAC® 4525 obtains a compressive strength of 1 Mpa (N/mm²) within 24 hours at 8 °C. The layer thickness and the temperature of the structural element influence the curing process. The amount of material applied and its inherent temperature influence the workable life of WEBAC® 4525. The initial temperature of both components prior to mixing must not fall below 5 °C.
