Product Details
3M™ Holdfast 70 Cylinder Spray Adhesive is an extremely versatile, fast-tacking industrial-grade spray adhesive characterized by a unique wide-web spray pattern, making it well-suited for bonding a variety of construction materials. This adhesive requires a short dry time while providing long open time, allowing for precise positioning of materials. It effectively waterproofs and protects against moisture. The product features a portable container that offers a low soak-in spray pattern with no overspray, creating quick bonds for both temporary and permanent needs. It bonds polystyrene without causing damage or degrading the surface, making it ideal for various substrates such as drainboard, FRP panels, insulation, foams, and fabrics. The adhesive's high solids content minimizes soaking into the substrate, maximizing holding power, and it is typically used in construction, specialty vehicles, RVs, manufactured housing, and HVAC applications. The product is packaged in a pre-pressurized, portable cylinder for a maintenance-free delivery system, though additional spray accessories, sold separately, are required. Recommended applications include one- and two-surface bonding, membrane bonding to concrete, insulation attachment, HVAC applications, geotextiles, drainboard, house wrap protective barriers, and OSB plywood.
