3M Adhesion Promoter 86A Transparent - 1 x Pint
3M™ Adhesion Promoter 86A enhances initial adhesion of polyurethane protective tapes and boots with acrylic adhesives on surfaces such as polyurethane paint, epoxy primers, and epoxy composites.
Overview
The 3M™ 021200-31592 Adhesion Promoter 86A is a liquid primer formulated to improve the adhesion performance of 3M™ Polyurethane Protective Tapes and Boots in demanding aerospace and industrial applications.
Designed for use with acrylic adhesives, this promoter accelerates the initial adhesion build rate on high-energy surfaces such as polyurethane paint, epoxy primers, and epoxy composites.
The polyamide and isopropyl alcohol-based formula dries in approximately 10 minutes, helping to minimise downtime and improve work efficiency.
Available in one-pint cans for larger coverage areas and pre-saturated wipes for quick application on smaller surfaces, 3M™ Adhesion Promoter 86A simplifies installation and helps provide reliable bonding.
Note: It is not intended for use where acrylic adhesive comes into contact with aluminium, stainless steel, carbon steel, or glass.
