Hypro® 2000X168LC VTB
Hypro (f.k.a. Hycar®) 2000X168LC is an improved, lower-color version of the HyproTM 2000X168 VTB (Vinyl-terminated polybutadiene). It is the reaction product of glycidyl methacrylate and HyproTM 2000X162 Carboxyl-Terminated polybutadiene (CTB).
Hypro 2000X168LC 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.
