Control of blistering in paint coatings

Thread Content

There are generally two types of reasons for coating bubbling: one is due to poor control during the paint production process, such as moisture in solvents or resins, or moisture in pigments and fillers； The second reason is loose management of coating application. Therefore, to control coating blistering, it is necessary to regulate both the paint production process and the painting application process. 1 Strengthen production management: During paint production, strictly control the moisture content of the pigments, fillers, and solvents used ； In the primer formula, try to avoid using soluble pigments and fillers ； When using solvents, it is necessary to take into account their vaporization equilibrium to avoid excessive residual solvent ； In high-humidity environments, use a base material with low permeability and strengthen construction management
