Product Description

3M Nitrile Industrial Adhesive 4491 is a solvent-based nitrile adhesive for flexible bonding of vinyl extrusions and sheeting, fabrics, leather, foam, and many plastics. Its low-viscosity formulation is intended for spray application and dries at room temperature; optional heat curing can increase physical properties. Finished bonds resist weathering, water, oils, fuels, many solvents, and plasticizer migration. Spray coating and flexible bond formation support decorative vinyl attachment to cabinets, wall linings, and flooring, as well as rubber and vinyl floor assemblies.

Key features

Spray-applied nitrile adhesive: The low-viscosity liquid can be coated onto vinyls, plastics, fabrics, leather, and foam.
Optional heat curing: Room-temperature drying forms the bond; subsequent heat curing can increase physical properties.
Fluid and weather resistance: Finished bonds resist water, oils, fuels, many solvents, plasticizer migration, and weathering.

Applications

Cabinet decorative vinyl bonding; wall lining and flooring; rubber and vinyl floor bonding.
