Product Application Instructions
1. Haminol 03A reacts with methylene acceptors at vulcanization temperatures, providing adhesion between rubber and carcass materials. For example, it reacts with resorcinol formaldehyde resin GLR-20, adhesive RE, and adhesive RS to form thermosetting resins. If the reaction occurs before vulcanization, the adhesive effect of this system will be lost. Usually, the rubber, filler, and methylene acceptor are first prepared at a higher temperature; then, Haminol 03A and other compounding agents are added during the final stage of rubber mixing.
2. The recommended ratio is 1.5-3 parts Haminol 03A, combined with 2-5 parts GLR-20 resin or other methylene acceptors.
