THIXON® P-11-EF

• This is a very mature product being part of the product line for 4-5 decades.
• It is a very good general use primer coat for rubber to metal applications. Providing excellent boiling water and salt spray resistance.

Mix Instructions

Diluents - MEK or MIBK
First, thoroughly mix THIXON® P-21 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® P-21 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 24.5% theoretical solids

1 part adhesive: 0.25 part diluent - estimate 19.6% theoretical solids

1 part adhesive: 0.5 part diluent - estimate 16.3% theoretical solids

1 part adhesive: 0.75 part diluent - estimate 14.0% theoretical solids

1 part adhesive: 1.0 part diluent - estimate 12.3% theoretical solids

1 part adhesive: 1.25 part diluent - estimate 10.9% theoretical solid

Application Technique

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

• Dipping: use undiluted, or dilute 10 parts product with 1 part MEK or MIBK.

• Spraying: dilute 2 parts product with one part diluents.

Drying the Film

The drying time is approximately 60 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). 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 205°C (250 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.
