Application

(1) Elastomers: Recommended for mineral-filled (silica, etc.) or carbon black pigmented sulfur cured elastomers at 1.0-2.0 phr to improve physical properties tensile, tear and abrasion resistance.

• Chartwell B-505.1 also improves vulcanization of all sulfur cured elastomers. Incorporation during compounding improves adhesion of other rubber, metal and synthetic materials to the molded rubber surface

 

(2) Adhesives: Recommended for epoxy (esp. dicyanamide cured) and urethane adhesives to enhance adhesion to metals, plastics, and elastomers. Increased T-peel strength. Improved resistance to moisture, heat, and corrosive environments.
