Hydrogenated Pure Monomer Resins
Regalrez Resins
These products are manufactured by selective hydrogenation of base resins polymerized using styrenic-based comonomers. Degrees of hydrogenation range from 30% to 100%. Softening points vary from 19° to 141 °C (66° to 286°F). These products are highly UV and oxidative resistant and do not contain any stabilizers.

Regalrez resins generate excellent tack and reduce sealant viscosity without significantly reducing slump resistance. Because of their excellent color and stability, these products are broadly compatible with block copolymers, oils, waxes, alkyds, and plastics. Uses include adhesives, caulks and sealants, film, rubber, plastics, and coatings.

General Product Characteristics
These are neutral resins with <1 acid number and <2 saponification number. (The relative degree of unsaturation can vary, with bromine numbers ranging from 2 to 8.) In general, the specific gravity as measured at 25°C (77°F) will be 0.95 to 1.05. Flash points as measured by COC are >232°C (>450°F) except for Regalrei 1018 [149°C (300°F)j.
