A METHOD OF WATERPROOF PAINT FILM OPERATION USING ISOCYANATE AND POLYUREA

摘要

An elastic waterproof coating construction method using isocyanate and polyurea is provided to reduce working time and prevent streaming down by shortening curing time. An elastic waterproof coating construction method using isocyanate and polyurea comprises: a step for forming a film with dropping down in an incline and a vertical plane and coating primer on an object to be coated to obtain strong adhesive force; and a step for spraying two-liquid material made of isocyanate and polyurea on the surface of the object using a spray gun with an air purge function and maintaining spray temperature between 65°C and 82°C.
