PERMABOND(r) HT20 is a one-part, moisture-cure hybrid adhesive for transportation body assembly, providing a high instant tack ideal for securing side and roof panels without fasteners. Panels can be aligned even after initial tack, and surface preparation is minimal. The product has 500% elongation that allows the adhesive to absorb energies created by trailer racking, thus alleviating the stress on the actual bond. Circle No. 161
