Casathix™ Polyamide Resins

Casathix™ 1898

Casathix™ 1898 is used to impart structure to alkyd resins. A level of 5 to 7% by weight on the base resin would normally be used, with a reaction time of 2 to 3 hrs at 200 to 230°C. The optimum Casathix™ 1898 level and reaction conditions required will depend on the base alkyd resin used and the degree of thixotropy required in the finished product. These should be established by experimentation.

Casathix™ 2092

Like Casathix™ 1898, Casathix™ 2092 is also used to impart structure into alkyd resins. A level of 5 to 7% by weight on the base resin would normally be used with a reaction time of 2 to 3 hrs at 200 to 230°C. The optimum Casathix™ 2092 level and reaction conditions required will depend on the base alkyd resin used and the degree of thixotropy required in the finished product. These should be established by experimentation. Compared with Casathix™ 1898, modified alkyd resins produced using Casathix™ 2092 give softer, more flexible coatings.
