Cyrez® is Hexamethoxy Methyl Melamine (HMMM) which is used as crosslinker for adhesion promoting or reinforcing system in rubber application, especially tire application. CYREZ® is methylene donor that is used in conjunction with methylene acceptors such as phenolic resin like Alnovol® from Allnex or resorcinol.
Advantage:
- No skin irritation
- No amine or ammonia by-product
- Better scorch protection than provided by methylene donor like hexamethylene tetramine (Hexa or HMT)
- No corrosive effects on steel and brass/bronze coated steel
- Dispereses readily
- Low dust level
- Good flowing properties
