Best Practices for Elantas (Altana) AD-1147
-
Surface Preparation
High strength bonds can only be obtained if all surfaces to be bonded are free of dirt, rust, chemicals, and mold releases. In addition, surfaces to be bonded should be sandblasted, etched, or degreased.
-
Application
Apply one or two coats of CONAP AD-1146 or CONAP AD-1147 (two coats are required for CONAP AD-1146-C and CONAP AD-1147-C) with a soft brush, allowing the adhesive to flow on the surface. Application may also be accomplished by spraying, roller-coating, or by doctor-blade. Air dry ½ hour between coats and one hour or longer after the final coat. Prior to the application of urethane, activate the primer by baking at 180ºF-200ºF for 1-2 hours.
NOTE: For optimum results, primer film thickness should be 0.0005 inches to 0.0015 inches. Under no circumstances should film thickness be less than 0.0005 inches.
Since these coatings contain a solvent, it is important that all residual solvent in the film be removed to obtain high bond strengths. A drying period of ½ hour at 70°C (158°F) is sufficient to accomplish solvent evaporation
-
Curing
Air dry ½ hour between coats and one-hour or longer after the final coat.
When bonding urethanes to metals, the drying period can be part of the preheat cycle used to bring the mold and part to the desired curing temperature. Preheat temperatures of 90-100°C (194-212°F) for 2 to 3 hours are not detrimental. The adhesion of the urethane to the primer film is excellent, and the adhesion of the primer to the metal is improved.
