The Importance of Primer for Wind Power Coatings

The characteristics of China's wind field

1) China's wind field is currently dominated by land-based land, mainly in desert and sandstorm-prone areas. It is raging with wind and sand, long sunshine, and with the change of climate, the environment is worsening;

2) In recent years, offshore wind power has gradually developed rapidly, but the environment encountered by high temperature, high humidity, high salt fog, and strong ultraviolet radiation is equally bad;

3) Corrosion protection of wind power generation equipment, lack of systematic planning and implementation;

The limitations of traditional protective coatings:

1) heavy finish, light primer

2) heavy appearance, light primer

3) Primers often do not provide effective protection when the topcoat is damaged

Traditional primer defects:

1) Low technical content, poor weatherability, low adhesion, poor film strength.

2) High viscosity and poor substrate aggressiveness.

3) The direct consequence is that the paint film is brittle, cracked, and pitted, resulting in rusting of the metal substrate, especially in hot and humid areas.

Wind protection coating anti-corrosion measures:

1) Metal Substrate Treatment: Hot Galvanizing

2) substrate surface coating: high performance coating

3) Primer performance, primer coating process, directly affect the life of the coating

Basic Requirements for High Performance Primers: Sealing

1) Adhesion

2) Film density

3) Strength of paint film
