3M 80 Rubber and Vinyl Spray Adhesive

Surface Preparation

Ensure all surfaces to be bonded are clean, dry and free from dust, oil or grease before application of adhesive.

Application

Ensure that the nozzle points toward the surface to be sprayed.

Turn the nozzle so that the tip points to the dot on the can rim.

Shake the can well before use. 10-20 seconds should be sufficient. An agitator ball has been introduced to ensure that the product is efficiently mixed with a minimum time of shaking.

Place materials to be bonded on a horizontal position. Hold the can 15-20 cm from the surface to be sprayed, keeping the can at an angle of 45 degrees. Apply at least two uniform and overlapping coats of adhesive to both surfaces to be bonded.

While spraying: a) Release the nozzle at the end of each pass across the surface being sprayed and depress the nozzle once the can begin to move on the return travel b) Push the nozzle of the can all the way down to avoid spluttering and to produce a uniform pattern.

After application, allow at least 3 minutes drying time before bonding.

Wipe tip with a rag soaked in Scotch Grip ™ Solvent No.2 whenever build up of adhesive is observed.

To prevent nozzle from blocking, at the end of each day turn the can upside down and press the tip until the spray is clear of adhesive and wipe tip with a rag soaked in Scotch Grip ™ Solvent No.2.

For operations requiring longer bonding range you have up to 15 minutes to make the bond.

Adhesive Build up may be minimized by: Shaking the can well before using.

Fully depressing the nozzle when spraying to avoid spluttering Adhesive which, accumulates around the “V” portion of the spray tip opening may be removed by wiping the “V” portion of the tip insert with a rag soaked in Solvent No.2. If adhesive should plug the nozzle, remove the nozzle from the can and immerse in a container of Solvent No. 2. Return the nozzle to the aerosol can when the adhesive has been removed.

Curing

After application, allow at least 3 minutes drying time before bonding.

Clean-Up

Excess of adhesive may be removed using Scotch- Grip Solvent No.2. The spray insert of the aerosol actuator used with Spray 80 Aerosol causes some adhesive build- up which make cause the spray pattern to become narrow and non-uniform.

NOTE: Scotch Grip Solvent No. 2 is highly flammable. When using solvents for clean up it is essential that proper safety precautions are observed.
