NORMOUNTÂ® Acrylic A3116GB is a 100% acrylic polymer with a proven history of long-term, high performance bonding. The unique viscoelastic substrate absorbs vibration and distributes stress forces over the entire bond area. The acrylic adhesive is resistant to UV radiation, high humidity and climate extremes, assuring long-term performance. All-acrylic construction provides for long-term performance. It bonds while creating continuous weather seal to prevent water infiltration. It prevents corrosion of dissimilar materials by eliminating the contact between them. It is compatible with polycarbonate and acrylic plastics.
