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

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

Appearance: Product is available in clear, white, off-white and wide range of colors and can be color matched according to a particular demand. 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: The product is easy to use with highly controlled rheological properties providing high resistance to sagging. This product has good resistance to yellowing over time. It has good gloss retention properties. This product has good water resistance properties. This product has resilient mechanical 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 gel coat is formulated to meet the rigid requirements of transportation, boating and sanitary applications.
