Identification & Functionality

THIXON® OSN-2-EF-VV Features & Benefits

Product Highlights
  • 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-VV does quite well as a stand alone coating in many general rubber to metal bonding situations.
  • THIXON® OSN-2-EF-VV is designed for faster curing cycles and possibly lower curing temperatures.

Applications & Uses

Use Recommendations
Mix Instructions

Diluents - Toluene or xylene, or a blend of 1 part aromatic solvent and 0.2-0.3 part MEK or MIBK

First, thoroughly mix THIXON® OSN-2-EF-VV with a high speed propeller-type agitator. If diluting, slowly add the diluent to the adhesive while mixing constantly. Otherwise, the polymer base may precipitate from solution.

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

1 part adhesive: 0.1 part diluent - estimate 19.1% theoretical solids

1 part adhesive: 0.2 part diluent - estimate 17.5% theoretical solids

1 part adhesive: 0.3 part diluent - estimate 16.2% theoretical solids

1 part adhesive: 0.4 part diluent - estimate 15.0% theoretical solids

1 part adhesive: 0.5 part diluent - estimate 14.0% theoretical solids

1 part adhesive: 0.75 part diluent - estimate 12.0% theoretical solids

1 part adhesive: 1.0 part diluent - estimate 10.5% theoretical solids

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

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

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

Drying the Film

The drying time is approximately 30 to 45 minutes at 16°-27°C (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 204°C (212 and 400°F) are recommended.

Pre-Bake Resistance

Coated inserts can be pre-baked for up to 5 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.


Equipment clean up should be done using recommended dilution solvents.
