3M™ Nitrile High Performance Rubber and Gasket Adhesive 847H, Black
3M™ Nitrile High Performance Rubber and Gasket Adhesive 847H is a solvent-based industrial adhesive formulated for bonding rubber components and gaskets in demanding environments. It combines nitrile elastomer adhesive technology with good weather, heat, and water resistance — ideal for automotive, industrial, and maintenance applications.
Key Features
- Strong adhesion to rubber and gaskets: Excellent performance on nitrile rubber, neoprene, SBR, EPDM, and similar elastomeric materials.
- Black adhesive formulation: Designed to match darker or black substrate surfaces for aesthetic and bonding consistency.
- Good resistance: Strong resistance to moisture, heat, oil exposure, and most environmental conditions.
- Solvent-based contact adhesive: Allows long open time and positioning before final contact bonding.
- Flexible after cure: Maintains elastic qualities that help absorb dynamic stresses without cracking.
Applications
- Rubber gaskets and seals — automotive, HVAC, machinery, pumps.
- Rubber sheeting to substrates — metal, wood, plastics.
- Insulation bonding — rubber insulation to ducts, pipes, housings.
- Vibration-resistant adhesive joints — reduces loosening under dynamic loads.
- Electric and mechanical equipment gaskets — seals and bonded assemblies.
- Maintenance, Repair & Operations (MRO) tasks in industrial facilities.
This adhesive is often used in automotive assembly, industrial equipment fabrication, HVAC gasket assembly, and general sealing tasks where elasticity and durability matter most.

Application Tips (General Guidance)
Surface Preparation:
- Clean surfaces to remove grease, oil, dirt, rust, or oxidation.
- Use a solvent wipe if necessary (compatible with substrates and application).
Application:
- Apply adhesive evenly to both surfaces.
- Typical contact adhesive procedure: allow adhesive to flash off until tacky but not wet.
Bonding:
- Align parts carefully and press firmly.
- Use rollers or pressure to achieve full contact and maximize bond strength.
Curing:
- Full bond development occurs as solvents evaporate and the adhesive film sets.
Safety & Handling
3M™ 847H is a solvent-based adhesive containing volatile organic compounds (VOCs) and flammable components. Always consult the official Safety Data Sheet (SDS) for full hazard and safety instructions.
Fire & Health Hazards
- Flammable — Vapors may ignite; keep away from heat, sparks, and open flames.
- Health risks: Vapors and contact with skin/eyes can cause irritation or sensitization.
- Inhalation: Avoid prolonged breathing of vapors — use in well-ventilated areas.
Safe Handling Practices
- Ventilation: Use in well-ventilated spaces or with local exhaust to reduce vapor exposure.
- PPE: Wear chemical-resistant gloves, safety goggles, and protective clothing.
- Skin contact: Wash promptly with soap and water.
- Avoid open flame and smoking near the product.
