STK Tape supplies original 3M VHB Tapes 5925 and 5952, two distinct caliper benchmark products within the 5952 Family - Low Surface Energy / Powder Coat structural bonding collection. Engineered with a highly conformable modified acrylic foam core coated on both sides with an aggressive modified acrylic adhesive, these double-sided tapes bond challenging low-surface-energy (LSE) plastics, powder-coated paints, and rigid metals without liquid adhesion promoters or surface primers.
3M VHB Tape 5925 Profile
3M 5925 is the thin-gauge profile (0.6 mm / 25 mil) designed specifically for assemblies requiring narrow gap tolerances, ultra-flush joint lines, and minimal bond line visibility. It offers high conformability on thin sheet metals and molded plastic parts while maintaining full structural shear strength on powder-coated finishes.
3M VHB Tape 5952 Profile
3M 5952 is the industry-standard flagship structural gauge (1.1 mm / 45 mil) engineered for maximum gap filling, heavy surface texture compensation, and high dynamic stress absorption. It is the premier choice for structural panel stiffeners, outdoor architectural cladding, and heavy-duty transportation assemblies.
Performance Features
Primerless Adhesion to Powder Coats & LSE Plastics: Directly bonds to powder-coated metals, polypropylene (PP), ABS, polycarbonate, and painted surfaces without liquid adhesion promoters.
Viscoelastic Dynamic Stress Relaxation: The conformable foam core flexes under dynamic impact, vibration, and thermal expansion differentials between dissimilar substrates.
High Initial Tack & Immediate Handling Strength: Rapid adhesive wet-out provides high green strength, allowing assemblies to move down the production line quickly without temporary clamping.
100% Weatherproof & Solvent Seal: Closed-cell acrylic structure seals out water, humidity, road salt, and decades of outdoor UV exposure.
