Polynt POLYCOR® TOOLING BR Gel Coat
Categories: Polymer; Thermoset

Material Notes: A pre-accelerated gel coat base on unsaturated polyester resin. It is cured using MEKP peroxide.

Appearance: Product is available in orange, green and black. The product is formulated to assure a hide in wet film thickness of 500µm. However some bright shades may have a hide slightly lower opacity.

Properties / Advantages: This product has chemical resistance properties This product has heat resistance properties. This product has good resistance to thermal shock caused by variation in temperature. This product has improved impact resistance properties It has excellent gloss retention properties.

Application: This gel coat is ready to use by application with a brush. Mix the product slowly but thoroughly for 10 minutes prior to each shift start up. Apply the correct film thickness. A wet film thickness between 300 to 600µm is required ideally working with a brush to ensure a level even thickness of 500 micron. Check that the correct level of MEKP is added. A level of 1,8% is recommended. Do not use more than 3% or lower than 1,2% MEKP catalyst. Minimum application temperature : 15°C This product is not designed for use with a spray gun.

Use Areas: This product is recommended for mold manufacturing process and provide durable surfaces to withstand the repeated moldings of GRP laminates.
