New urethane gel coat for the wind energy market

The gel coat is available in clear for wind blades and pigmented for nacelles. The clear gel coat AGC200 features good adhesion to epoxy, polyester, vinyl ester, and urethane composite substrates, low viscosity for smooth application, and the option of having open time for lamination up to three days. The clear and transparent liquid remains as such in a cured film. The pigmented gel coat AGC10000 series features similar adhesion properties and open time for lamination along with good outdoor durability and dimensional stability.

Benefits offered by both gel coats include solvent-free composition, flexible urethane film, and the ability to be modified to meet application requirements. The clear gel coat enables visual inspection of composite laminate for defects and may be recoated using high-solids urethane and epoxy primers and urethane topcoats. The pigmented gel coat can be applied at lower film thickness than traditional gel coats and provides high gloss and distinctness of image.
