About Sealant Flexibility

Impact-Resistant Structural Glass Sealants


Repair equipment and vehicle windows with these sealants that are rated to withstand impact within three hours of application. They’re non-sagging, so they won't drip from vertical and overhead surfaces. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. They’re crash tested and meet Federal Motor Vehicle Safety Standard 212 for windshield mounting.
Elongation indicates flexibility—the higher the value is, the more joint movement a sealant can sustain.
A primer is required. For best results use P591 for composites, glass, and fiberglass and P592 for aluminum, steel, and stainless steel.
