Adhesive composition for bonding rubber to metal

An adhesive composition is comprised of a film forming polymer, (ii) a lower crystallinity polynitroso compound, (e.g., poly-(1,4-phenylyenazine-N,N-dioxide)), (iii) a higher crystallinity polynitroso compound (e.g., poly-(1,4-phenylyenazine-N,N-dioxide)), and (iv) a carrier liquid. The composition is useful in bonding metal and rubber to make, for example, components to damp noise, vibration or harshness.

INTER-PENETRATING ELASTOMER NETWORK DERIVED FROM GROUND TIRE RUBBER PARTICLES
20210115230 · 2021-04-22 ·

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
