Strongsville, Ohio -- PPG Industries' commercial coatings group is to market and distribute a new urethane gel coat for the wind-energy market.
This new gel coat is available in clear form for wind blades and in pigmented form for nacelles: it was developed and made by Plasticolors Inc. of Ashtabula, Ohio.
PPG and Plasticolors will work together to address the advanced coating requirements of the rapidly expanding wind-energy industry, said a 7 Jan statement from Strongsville, Ohio-based PPG.
"The gel coat we've developed will be attractive to wind-turbine manufacturers as a high-performance alternative to epoxy and polyester gel coats in use today," said Scott Becker, president and chief executive officer, Plasticolors, in a PPG statement.
"Since our expertise is manufacturing and development, we wanted to make sure we worked with someone who could give this product technology maximum exposure and the industrial consideration it merits. PPG has a long-term focus on, and understanding of, the wind-energy industry. Their global sales and distribution channels make them a perfect partner for this technology," Becker added.
Steve Podlas, brand manager, industrial segments, for PPG's commercial coatings group, said, "Together, Plasticolors and PPG bring a complete commercial and technical package to the wind-energy market when combined with our urethane primer, topcoat and technical service. Plasticolors has created a superior product, a product we know will be seen as the premium standard in the field."
PPG says the AGC200clear gel coat has "excellent adhesion to epoxy, polyester, vinyl ester and urethane composite substrates, as well as low viscosity for smooth application." It also gives the option of having open time for lamination of up to three days. The clear, transparent liquid retains these attributes in a cured film, said the company.
The AGC200 pigmented gel coat has similar adhesion properties and open time for lamination, as well as excellent outdoor durability and dimensional stability, said PPG.
Both gel coats offer solvent-free composition, a flexible urethane film, and can be modified to meet specific needs, according to the supplier.
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.
Coatings and fibreglass supplier PPG makes products which make wind-energy turbine blades and towers stronger, lighter and more efficient.
High-performance PPG coatings offer adhesion properties for extreme operating environments and are available in a range of water-based liquid, high-solids and low-volatile organic compound technologies. PPG fibreglass products for turbine blades help to improve fatigue performance by enhancing the resin bond.
