    Shelf Life Details Store product at 60-80°F (15-27°C) for maximum storage life. Higher temperatures reduce normal storage life. Lower temperatures cause increased viscosity of a temporary nature. Rotate stock on a “first in-first out” basis.; When stored in the original unopened container, under the conditions recommended, this product has a shelf life of 24 months from date of manufacture.

  • Best Practices for 3M Nitrile High Performance Rubber & Gasket Adhesive 847H

    *See Terms of Use Below

    1. Surface Preparation

      Surface Preparation: Remove all dust, dirt, oil, grease, wax, loose paint, etc.

      Wiping with a solvent such as methyl ethyl ketone (MEK) or 3M™ Citrus Base Cleaner will aid in preparing the surface for bonding.

    2. Application

      Note: Appropriate application equipment can enhance adhesive performance. We suggest the following application equipment for the user’s evaluation in light of the user’s particular purpose and method of application.

      Pumping: 5 Gallon Pail Dispensing System: Pump – 4:1 double acting ball type check pump, 4 cu. in/cycle 3 in air motor.

      Pail cover required to reduce solvent loss.

      55 Gallon Drum Dispensing System: Pump – 4:1 ratio double acting ball type check pump, 4 cu. in/cycle 3 in air motor, bung style pump.

      Accessories: Hose – nylon lined, 500 psi working pressure minimum.

      Spray: Rubber & Gasket Adhesive 847 Production Type Spray Equipment

      Airless spray: This adhesive is not recommended for airless spraying.

      2 H.P. Compressor for intermittent use. 3 H.P. Compressor for continuous use.

      To Measure Fluid Flow: Pressurize fluid source only

      pull trigger

      flow material into measuring device for 60 seconds

      increase or decrease fluid source pressure to obtain desired fluid flow.

      All material hoses should be nylon or PVA lined.

      Brush: Typical brushes designed for oil based paints may be used.

      Application Temperature: For best results the temperature of the adhesive and surfaces to be bonded should be at least 65°F (18°C).

      Application: Stir well before using

      Porous Surface(s): Brush, flow or spray a thin, even coat of adhesive to one or both surfaces. Coating both surfaces is preferred since it gives greater strength and permits longer open time before bonding. Very absorbent materials may require more than one coat. Bond while adhesive is still wet or aggressively tacky. Join surfaces with firm pressure.

      Non-Porous Surfaces: Brush, flow or spray a thin, even coat of adhesive to both surfaces. Allow adhesive to dry until tacky. Join surfaces with firm pressure.

    3. Curing

      Drying Time: Drying time depends on temperature, humidity, air movement, and porosity of the materials bonded. Greater immediate strength may be obtained by heat or solvent reactivation. See Reactivation below.

      Reactivation: To solvent reactivate, coat both surfaces with adhesive. Allow to dry tack-free. Lightly wipe one surface with a solvent such as methyl ethyl ketone

      Complete bond within 30 seconds.

      To heat activate, coat both surfaces with adhesive. Allow adhesive to dry completely. Reactivate by heating one or both surfaces to a minimum of 180°F (82°C). Assemble immediately (while hot), using firm pressure to ensure contact.

      Curing: 3M™ Nitrile High Performance Rubber & Gasket Adhesives 847 and 847H may be heat cured to obtain improved physical properties. Cure assembled parts at time and temperature listed using 100 psi pressure on the bond line.

    4. Clean-Up

      Excess adhesive may be removed with a solvent such as methyl ethyl ketone (MEK) or acetone, preferably while adhesive is still wet.

      When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions and directions for use.
