Product presentation:

“YUHONG”brand SPU-321 Polyurethane Construction Sealant is solidified type macromolecule sealant obtained from double components reaction. Component A is the polyurethane prepolymer is obtained from the polymerization reaction of isocyanate and polyether polyol , component B consists of various auxiliaries such as active hydrogen compounds of polyether polyol and polyamine , of other auxiliaries such as dye, thixotropic agent , antioxidant and catalyst. When used, we mix A and B with a certain proportion and stir into paste, then pour into gap, after chemical reaction, it forms an elastic and firm sealant material.
