Applications & Uses

Markets: Industrial
Applications: Industrial — Chemical & Industrial Manufacturing
Tooling & Moldmaking
Formulation Guidelines: Formulation:

Crystic Gelcoat 11PA must be allowed to attain workshop temperature before use. Stir well by hand or with a low hear mixer to avoid aeration, and then allow to stand to regain thixotropy.
The recommended catalyst is Butanox M50 (or other equivalent catalyst) which should be added at 2% to the gelcoat.

Recommended Testing:

It is recommended that customers test all pigmented gelcoats before use under their own conditions of application to ensure the required surface finish is achieved.

Gel Time:

Catalyst level and temperature will influence the gel time. Typical gel time at 20°C of Crystic Gelcoat 11PA with 2% Butanox M50 is 9 to 11 minutes.
