Learned recently, the group develops western (WestDevelopmentGroup, WDG) already developed give two kinds new-style without coating of solvent silicone housetop: HSS535 and HSS540R2R, namely coating of housetop of balata of silicone of odd constituent, wet solidify, use at housetop of polyurethane foam spray.
HSS535 and HSS540R2R all are product of material of silicone balata spray, do not have because of containing solvent volatile, compare with phase of data of housetop of conventional petroleum composition, more conduce to environmental protection. In addition, the balata of 20% third of 3 yuan of second that can reclaim are contained in HSS540 (contain double-loop the fifth of the ten Heavenly Stem 2 rare) (EPDM) , because this can improve the physical performance of coating. In the meantime, this coating still can prevent ultraviolet ray and not easy ageing.
HSS535andHSS540R2R also passes association of American material experiment (AmericanSocietyofTestingMaterials)E108 blaze spreads experiment, obtain the assess of class A fire retardant coating. Silicone coating can be formed without mark, waterproof sealed layer, gas of the Chinese People's Anti-Japanese Military and Political College and ozone oxidation reach pluvial snow wind erosion, still can fight crack, fight come off, shrinkproof, and prevent to harden and become fragile.
The group develops western (WDG) devotes oneself to housetop silicone and polyurethane foam technology. Coating of housetop of colophony of total silicon of company peculiar 14™ not only function tall and environmental protection.
