Wind turbine blade coating

Wind turbine blade coating

Wind turbine blade coating belongs to the high-weather resistance benzene-neopentane glycol coating, also known as benzene gel coat. It is a special protective coating for the outer surface of wind turbine fibreglass blades. This benzene gel coat is the first barrier for blades to resist the harsh outdoor environment. It is mainly used for wind turbine blade shells on land and at sea.

● Super weather resistance, anti-violet, anti-yellowing

● Resistant to rainwater erosion and wind and sand wear

● Resistant to hydrolysis and salt fog (ofshore wind power)

● Good toughness and crack resistance

● The surface is dense and smooth.

● Large outdoor FRP wind power components such as onshore wind power blades, offshore wind power blades, fan cabin covers, etc. This benzene gel coat delivers stable protective performance for these FRP parts under long-term outdoor exposure.

FAQ

Q: Advantages of benzene coating?

A: Stronger adhesion: better binding with benzene resin and structural layer, and the probability of stratification.

Q: Short board of benzene gel coat?

A: The mobility of the tactile change is slightly poor, and the manual brush construction leveling is slightly inferior to that of phthalate.

Q: What is benzene gel coat?

A: Our benzene gel coat is a high weather-resistant surface material for FRP components. It serves as the primary protective layer against harsh outdoor conditions. It delivers UV resistance, anti-yellowing performance and good surface smoothness for wind power and marine composite products.

Q: Where can your benzene gel coat be applied?

A: Our benzene gel coat is widely used for large FRP parts. Typical applications include onshore & offshore wind turbine blades, fan cabin covers, yacht hulls and other marine composite structures exposed to long-term outdoor harsh conditions.

Q: How about the mechanical performance of your benzene gel coat?

A: Our benzene gel coat possesses good flexibility and crack resistance. It can accommodate minor substrate deformation without peeling. It resists impact and abrasion, preventing surface cracks that allow moisture to penetrate the underlying fiberglass substrate.

Q: What key points should we notice during construction of benzene gel coat?

A: When applying our benzene gel coat, keep the FRP substrate clean and dry. Control the spraying thickness reasonably. Ensure proper curing to form a compact surface layer and maximize its anti-erosion and weather-resistant properties in service.
