Molecular formula : MW : CAS :
nature : the use of synthetic resin or plastic objects Preparation protective coating method. Usually these are the following : (a) solution spraying method, synthetic resin or plastic dissolved in solvent-based coatings made solution, and then usually common method of coating sprayed on objects, to be formed after solvent evaporation coating; (2) thermal spray method, synthetic resin or plastic ( by adding a small amount of solvent or) directly underneath the thermal spray (available steam or hot air with spray) sprayed on objects, or a small amount of cooling by evaporation of solvent evaporates after coating; (3) The flame spraying method, synthetic resin or plastic powder into the air from the high-pressure spray gun, the adoption of gas flames lap was melting into semifluid and sprayed on objects on the surface, cooling after forming coating; (4) boiling spraying method, the powder synthetic resin or plastic with air or inert gas so "boiling" and then pre-heated to above resin melting point metal components (but not exceeding the temperature of the resin Degradation temperature) Immersion "boiling layer" which was sprayed by a certain time after the removal Serve cool or curing coating. Spraying than ordinary plastic coating materials useful provinces (to avoid using solvent), high efficiency, thick coating characteristics. In particular, France and flame spraying boiling spraying method can be used poorly soluble synthetic resin or plastic.
