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.

Clean-up

Equipment clean up should be done using recommended dilution solvents.
