ThinkBond 9 Zinc-Free Rubber-to-Metal Adhesive NBR to Metal
ThinkBond 9 is an advanced zinc-free adhesive engineered for bonding peroxide-cured nitrile rubber (NBR) to steel substrates, specifically optimized for industrial applications requiring strict environmental compliance. With a simplified 1-hour ambient curing process and superior tensile performance, it delivers reliable adhesion for metal-rubber composites in harsh operating conditions.
✅ Zero-Zinc Formula
Meets latest eco-regulations (REACH/RoHS) by eliminating zinc compounds – safe for automotive and food-contact applications.
✅ Optimized for NBR+Metal Bonding
Precisely formulated for peroxide-cured NBR vulcanization systems, ensuring chemical compatibility with steel components.
✅ Rapid Processing
Achieves full bonding strength with 1-hour air drying at workshop conditions (20-35°C, 50-70% RH).
✅ Certified Tensile Performance
Exceeds industry standards with 22-25 MPa tensile strength on sandblasted & alcohol-cleaned surfaces.
Surface Prep:
Sandblast metal
Degrease with isopropyl alcohol
Application:
Apply adhesive evenly on metal surface
Curing:
Air-dry for 60 minutes near equipment
