HYPRO® 2000X168LC polymer has improved lower color and offers better viscosity stability with age and temperature than HYPRO® 2000X168 VTB (vinyl-terminated polybutadiene). It is the reaction product of glycidyl methacrylate and HYPRO® 2000X162 carboxyl-terminated polybutadiene (CTB). HYPRO® 2000X168LC polymer is a low-molecular-weight, methacrylate-functional liquid synthetic rubber. It is a 100% solids reactive polymer used primarily as an additive in acrylic adhesives, sealants, coatings and composites.
