HSP-7401

HSP-7401 series is a polyurethane primer which offers the adhesion to composite substrate, flexibility and profile-filling properties required in wind turbine blade finishing operations. Additionally, HSP-7401 may be top-coated in a little as 30 minutes, which reduces cycle time and speeds throughput.

The product is designed for spray application and is compatible with a wide array of equipment, including robotic equipment. HSP-7401 may also be roller-applied. Its flow and leveling properties work together with PPG’s proprietary topcoat technology to produce an ultra-smooth surface which enhances turbine energy output.

HSP-7401 has been thoroughly tested as a system with PPG’s AUE-50000 series erosion-resistant polyurethane topcoat, producing outstanding results at reduced overall film thickness.
