Product Data Sheet

3M™ Adhesion Promoter 111 is a high-performance, isopropyl alcohol-based adhesion enhancer engineered to improve the bond strength of 3M™ VHB™ tapes across a wide range of substrates. Designed for industrial and manufacturing environments, this fast-acting primer promotes stronger, faster adhesion on challenging surfaces such as bare metals, galvanized steel, and painted materials.

This versatile adhesion promoter acts as both a surface cleaner and primer in a single step, helping streamline assembly processes and reduce application time. Its quick-drying formula—typically drying in about one minute—minimizes downtime while maximizing productivity.

3M™ Adhesion Promoter 111 significantly increases bond strength and improves adhesion build rates, even in cooler temperature environments. It also enhances the long-term durability of adhesive bonds by improving resistance to moisture, chemicals, and environmental conditions.

Ideal for use in transportation, electronics, construction, and general industrial assembly, this adhesion promoter is commonly applied prior to tape bonding to ensure optimal performance. Its low-odor, transparent formulation provides ease of use while maintaining a clean application appearance.

Whether you’re bonding metal panels, mounting components, or improving adhesion on painted surfaces, 3M™ Adhesion Promoter 111 delivers a reliable, efficient solution for maximizing tape performance and ensuring long-lasting bonds.
