- Gel time
Catalyst level and temperature will influence the gel time. At 25°C, typical gel time of Crystic Gelcoat G 976SMK with 2% Butanox M50 is 8 to 10 minutes.
- Application Guidelines
Crystic Gelcoat G 976SMK has been specially designed for the molding of swimming pools. It will provide high chemical and hydrolysis resistance.
Application Temperature 18 – 20°C Dilution Ready for use Catalyst 2% Butanox M50 Nozzle Airless Gun 423 – 631 Pressure 3 to 4.5 bars Distance to Mold 50 cm minimum Wet Film Thickness 600 – 800 microns - Applications
- Crystic Gelcoat G 976SMK has been specially designed for the molding of swimming pools. It will provide high chemical and hydrolysis resistance.
- Formulation Guidelines
Crystic Gelcoat G 976SMK must be allowed to attain workshop temperature before use (18 – 20°C). It is highly recommended to stir the product with a low shear mixer and then to let it rest before use. The product only requires the addition of catalyst to start curing. The recommended catalyst is Butanox M50 (or other equivalent catalyst) which should be added at 2% in the gelcoat.
