The weather resistance of PU color paste depends on many factors, including formulation, additives, construction methods, and environmental conditions. The following are the weather resistance characteristics of PU color paste in general:
Strong weather resistance: Compared with many other coatings and color pastes, polyurethane color pastes generally have strong weather resistance. This means that they can maintain the stability of color and appearance under long term exposure to various weather conditions.
UV stability: Polyurethane color pastes generally have good ultraviolet (UV) stability, which can resist the erosion of ultraviolet rays and prevent the color from fading or changing due to ultraviolet radiation.
Anti pollution: Some PU color pastes may have anti pollution properties, which can resist the adhesion of dirt and pollutants and keep the surface clean.
Chemical resistance: Polyurethane color pastes may have certain chemical resistance, which can resist the erosion of chemicals such as acids, alkalis, and solvents, maintain color stability and surface integrity.
Abrasion resistance: Some PU color pastes may have good abrasion resistance, which can resist surface wear caused by friction and extend the service life of the color paste.
Environmental adaptability: Polyurethane color pastes are usually able to adapt to various environmental conditions, including high temperature, low temperature, humidity, etc., and maintain stable color and appearance.
Waterproofness: Some PU color pastes may have good waterproof properties, which can resist the penetration of water and protect the coated surface from moisture damage.
