Bonding Gum
Our Bonding Gum (also known as Cushion Gum) is a high-performance, tacky, uncured rubber compound formulated for use as an adhesive in the tire retreading process. This product creates a secure bond between the new tread and the old tire casing, ensuring a strong, durable connection. It also acts as a cushioning layer that absorbs shock and provides additional flexibility for the retreaded tire.
