SR022 Bonding Resin Adhesion Promoter for Rubber Adhesion and Steel Cord Bonding with Resorcinol Formaldehyde Pre-condensate
Product Details
Rubber Adhesion Bonding Resin
,Steel Cord Bonding Adhesion Promoter
,Resorcinol Formaldehyde Pre-condensate SR022
- Reacts with methylene donors during vulcanization to form bonding resins
- Creates dual bonding mechanisms: chemical bonding with cords and curing with rubber double bonds
- Enhances adhesion between synthetic fiber cords, brass-plated steel cords, and vulcanizates
- Improves mechanical and dynamic properties
- Provides superior performance retention after aging
- Non-fuming formulation - superior to pure resorcinol and masterbatch R-80
- Incorporate SR022 during the first stage of the mixing cycle
- Recommended dosage: 1.5-2.0 phr
