L&L BOND
L&L Heat-Activated Structural Adhesives
L&L Bond
Lightweight, High Performance Engineered Solutions for Bonding.
L&L Bond Structural Adhesive Tapes are high-performance, heat-activated structural adhesives that are applied prior to the E-coat bake process and cure in the E-coat oven to provide structural bonding. Our high-expandable structural adhesives foam to bridge varying design gaps.
Tacky in the uncured state, these heat-activated adhesives are ideal for use where access is limited for welding or mechanical fastening. The material includes a permanent film on the top surface for easy handling that transforms into an adhesive with heat activation. When bonding dissimilar substrates, the tapes resist stresses created by coefficient of thermal expansion differences while preventing galvanic corrosion as a nonconductive adhesive spacer.
