Carboxylic Acids as Surface Treatments to Improve Adhesion to Polyamide Substrates

摘要

1. Less toxic carboxylic acids can be as effective or better than phenol as surface treatments to improve adhesion to polyamides. 2. Alpha hydroxy-carboxylic acids are more effective than simple carboxylic acids in improving adhesion to polyamide 6,6. 3. Aliphatic carboxylic acids provide the greatest increase in adhesion to polyamide 6,12, although the gain is small.
