Weathering Heat Reflective Color Coated Steel

The production of weather-resistant heat-reflective color coated plate to solve the common color coated plate to absorb high heat and reduce the service life of the problem is eco-friendly products and energy saving products pioneer, while making the roof is called "cold roof." Product performance indicators in: The initial solar reflectance (TSR)> 0.25 for all colors, and the sunlight reflectivity (TSR)> 0.15 for three years; Most of the products (except for a few dark products) of the sun reflection coefficient SRI ≥ 29, part of the light-colored products SRI ≥ 78; The product has excellent scratch resistance, the use of probe scratch tester test load 1500 grams, the film is not Li broken; Resistance to heat and humidity, after non-condensing hot and humid test chamber placed 1000 hours, the product without bubbles, cracks, paint peeling, no color, gloss and hardness changes; Resistance to boiling water, the product in 100 ℃ boiling water bath for 24 hours, no loss of light, discoloration, cracking, blistering, shedding and so on; Acid resistance, the product soaked in 5% hydrochloric acid 24 hours, no significant change in appearance; Alkali resistance, the product in 5% sodium hydroxide soak for 24 hours, no significant change in appearance; UV lamp accelerated aging test, the product in the QUVA-340 UV lamp chamber test, fluorocarbon system 4000 hours, 2,000 hours of polyester modified polyester system, 1500 hours after the polyester system, the product powder level ≤ 1, no Rust, blistering, cracking and other defects.
