Product information
Product Application Notes
1. Haminol 03A reacts with methylene acceptors at the vulcanisation temperature and acts as a bonding agent for rubber and skeletal materials. For example, it reacts with resorcinol formaldehyde resin GLR-20, binder RE, binder RS, etc. to produce a thermosetting resin. If the reaction takes place before vulcanisation, the bonding effect of the mating system is lost. The rubber, filler and methylene acceptor are usually prepared first at a higher temperature; then, at the final refining stage, Haminol 03A and other mating agents are added.
2. The recommended ratio is 1.5-3 parts Haminol 03A with 2-5 parts GLR-20 resin or other methylene acceptors.
