Water Resistant Adhesives
For structural adhesives that resist exposure to water, humidity and steam, Master Bond offers a complete line of epoxies, silicones, polyurethanes, polysulfides and UV curable adhesives. Many specific epoxy grades are formulated to resist liquid and vapor exposure in both tap and salt water without degradation of bond strength, even at elevated temperatures.
Master Bond's database of chemical immersion tests extends up to 10 years
Important Performance Properties for Master Bond Water Resistant Structural Adhesives
