ASTM D429 – Rubber Adhesion Test Methods
ASTM D429 covers test methods for measuring how well rubber adheres to rigid substrates such as metal. It matters for rubber-to-metal bonded parts like mounts, bushings and seals, where the bond has to hold under load.

Why it matters
Adhesion tests help compare bonding systems, confirm process control and catch weak bonds before parts ship. Coi Rubber makes rubber-to-metal bonded parts and can discuss the test method that fits your application.
