Designed to eliminate the growing probability of read-through, LORD Corp. has announced a new acrylic adhesive system, LORD 810 LRT. When cured with LORD Accelerator 20, LORD 810 LRT acrylic adhesive creates a flexible system for bonding metals, such as aluminum, galvanized steel and cold rolled steel (CRS), as well as engineered plastics such as PC-ABS and ASA. The adhesive system reportedly delivers fast cure speed and strong bonding with little to no bond-line read-through (BLRT). LORD Accelerator 20 allows precise control of the adhesive bond-line thickness due to its content of glass beads.
According to Jim Perritt, U.S. and Canada Sales Manager for LORD Product Assembly, this system was developed to alleviate the read-through problem that occurs when the adhesive can be seen through the substrate. “Anything assembled with thin-gauge materials (composite or metal) can suffer from this surface distortion problem,” he said. Being able to see the adhesive line is not acceptable by automotive OEMs looking to achieve a world-class finish.
