5-60% weight protective colloid
stabilized polymer solids wherein the protective colloid
is a partially hydrolyzed polyvinyl alcohol having a degree of hydrolysis less than or equal to 95% mol, and the weight percents of cement, filler and protective colloid
stabilized polymer solids are based on the total weight of the construction adhesive.
Its performance is unique and it can resist mineral oils, grease, lubricant and most organic solvents; it can not absorb sound but can accurately transmit sound and at the same time has a good bonding strength, membrane flexibility and smoothness, oil resistance, solvent resistance, protective colloid
, gas blocking, wear resistance, as well as water resistance after special treatment.
