The inorganic zinc rich primer used on the connection surface of high-strength bolts has anti-slip coefficient index requirements.The performance of inorganic zinc rich products in normal use can not meet the index requirements and the anti-slip requirements of normal bridge steel structure,which afects the service life of the bridge and even leads to safety accidents.Therefore,based on the unique inorganie zine rich resin,a certain amount of anti-slip fller and additives were added to meet the standard requirements of anti-slip and meet the anti-slip requirements on the connection surúce of high-strength bolts.
