Applications & Uses
- Product Uses
- This product can also be used in conjunction with methylene acceptors (Alnovol® PN 760 or Resorcinol) in rubber compounds to increase modulus, tensile, stiffness and hardness.
- Cyrez® 963 can be used at the following levels for initial evaluations.
Suggested Levels
- Cyrez® 963 2 - 5 phr
- Alnovol® PN 760 1.5 - 3 phr or Resorcinol 1,5 - 3 phr or Resorcinol formaldehyde resin 2 - 4 phr
- Product Applications
- Cyrez® 963 finds wide application as adhesion promoter and crosslinker for bonding rubber to organic cord and wire reinforcement materials.
- Cyrez® 963 (HMMM) offers several advantages over the older hexa methylene tetramine (HEXA or HMT) system.
- Cyrez® resins are relatively nontoxic and present little hazard of dermatitis.
- An additional advantage is that they are not corrosive to steel cord, polyester cord or metal molds.
- This property is important when considering adhesion promoters.
- Cyrez® resins are much more suitable as methylene donors, as opposed to HMT which produces ammonia.
- When used in conjunction with Alnovol® PN 760 or resorcinol, Cyrez® resin offers the ultimate in rubber adhesion giving optimum bonding strength.
