THIXON® OSN-2-EF

THIXON® OSN-2-EF

THIXON® OSN-2-EF is a general purpose one-coat adhesive used for bonding various elastomers to metals, such as hot and cold rolled steel, stainless steel alloys, brass, aluminum, and zinc plated metals._x005F THIXON® OSN-2-EF bonds Natural Rubber (NR), Polybutadiene (BR), Polyisoprene (IR), Styrene Butadiene Rubber (SBR), Chloroprene (CR) and Polyacrylate (ACM)._x005F THIXON® OSN-2-EF is also used for post-vulcanization bonding. In addition, THIXON® OSN-2-EF bonds rubber to synthetic fibers such as rayon and polyester. It is a good general purpose rubber to substrate bonding agent that can be used as single coat or two coat system. The use of a ROBOND, THIXON® or MEGUM® primer or a two coat system will provide the best environmental resistance, however THIXON® OSN-2-EF does quite well as a stand alone coating in many general rubber to metal bonding situations.

Applications & Uses

Use Recommendations
Mix Instructions

Diluents - Toluene, xylene, or use a blend of 1-3 parts aromatic solvent and 1 part MEK or MIBK
First, thoroughly mix THIXON® OSN-2-EF with a high speed propeller-type agitator. If diluting, slowly add the diluents to the adhesive while mixing constantly. Otherwise, the polymer base may precipitate from solution.

Continue to mix THIXON® OSN-2-EF while spraying or dipping to keep the dispersed solids from settling to the bottom. This will assure that a homogenous mixture of the adhesive is applied.

1 part adhesive: 0 part diluent - estimate 25.0% theoretical solids
1 part adhesive: 0.1 part diluent - estimate 22.7% theoretical solids
1 part adhesive: 0.2 part diluent - estimate 20.8% theoretical solids
1 part adhesive: 0.3 part diluent - estimate 19.2% theoretical solids
1 part adhesive: 0.4 part diluent - estimate 17.9% theoretical solids
1 part adhesive: 0.5 part diluent - estimate 16.7% theoretical solids
1 part adhesive: 0.75 part diluent - estimate 14.3% theoretical solids
1 part adhesive: 1.0 part diluent - estimate 12.5% theoretical solids

Application Technique
  • Brushing: apply product undiluted. To obtain the required film thickness, brush on a heavy wet film without brushing excessively.

  • Dipping: use a blend of 1-3 parts aromatic solvent and 1 part ketone as the diluent. Dilute 6 to 8 parts of product with 1 part of this diluents blend. This will give a dry film thickness of 0.6 to 0.8 mil.

  • Spraying: dilute 2 parts product with 1 part diluent for a viscosity of 18 - 22 seconds, #3 G.E. Zahn cup.

Drying the Film

The drying time is approximately 30 to 45 minutes at 60°-80°F. At lower temperatures, dry longer. The drying time can be shortened by force drying 5 minutes at 82°C (180°F) or 2 minutes at 104°C (220°F) or increasing the air flow, or both. Do not dry at temperatures above 120°C (250°F).

Molding and Curing

Can be used with all common molding and curing methods. Cure temperatures between 100°C and 212°C (212 and 415°F) are recommended.

Pre-Bake Resistance

Coated inserts can be pre-baked for up to 6 minutes at 163°C (325°F) without adversely affecting bond quality

Dry Film Stability

Excellent dry film stability. Inserts coated with product can be stored for several weeks if protected from contaminants.

Clean-up

Equipment clean up should be done using recommended dilution solvents.
