Storage stability of silicon modified road sealant end groups are all silicon-carbon bond. Because of its hydrophobic sealant prepolymer reduced sensitivity to moisture, under dry nitrogen atmosphere, sealant quite stable storage, and silane-functional methyl, dimethyl compatible with most additives Good In the presence of a suitable curing agent, can play a better balance of storage stability and high activity. Weather-resistant silicon modified road sealants prepolymer is characterized by a molecular chain unsaturated bond content is very low, with excellent weather resistance and aging resistance, climate change and, UV radiation. Outdoor use tree years and no surface cracks, cracks or discoloration. Construction sealant mostly low modulus varieties, namely high elongation, low hardness sealant manufacturers, and most cases are not required to have sagging performance. For highways and airports polyurethane sealant generally high modulus plastic sealant construction technology, its performance is: Shore A hardness of 40 to 60, 100% modulus of 0.5 ~ 0.7 MPa polyurethane sealant, back elasticity of not less than 85%, with good cohesion, no creep, anti gravel and other foreign objects embedded, high-speed traffic abrasion resistant sealant Nanjing Bridge _ _ St. Rui polyurethane sealant provided by the Xinxiang City of St. Rui Bridge Conservation Technology Co., Ltd. Nanjing Rui Bridge St. sealant _ _ Polyurethane sealants are Xinxiang City of St. Rui Bridge Conservation Technology Co., Ltd.
