- Spray, Brush, or Roll Application
- Single-Surface Insulation Bonding
Product Description
3M Fastbond Insulation Adhesive 49 is a water-based, high-solids pressure-sensitive adhesive for bonding lightweight insulation, fiberglass, fabric, felt, and foam to metal and wood. Aggressive tack and high initial grab permit single-surface application, while the high-solids formulation limits soak-in. The adhesive can be sprayed, brushed, or rolled and provides open time for positioning insulation after coating. It forms a permanent bond for HVAC fiberglass insulation, general insulation installation, and hanging lightweight fabrics or foam.
Key features
- Single-surface bonding: Aggressive tack and high initial grab allow adhesive application to one surface before insulation placement.
- High-solids water-based formulation: The formulation limits soak-in when bonding insulation, fabric, and foam.
- Spray, brush, or roll coating: The adhesive can be applied with any of these three methods before positioning the lightweight material.
Applications
Insulation installation; HVAC fiberglass insulation; hanging fabric, felt, foam, and related lightweight materials.
