Silicone modified polyester coatings have excellent properties
Resistance to weather, acid, stain and inorganic substrates
It is widely used in the precoating of metal sheet.
Coating of machinery and equipment and weathering decoration of building interior and exterior walls. with
Hydroxy-terminated polyesters and organic polyoxides can be used
Silicon oligomers (the average hydroxyl group number per molecule is about 3 to 5)
Line modification. The hydroxyl group on the silicone resin is etherified in the first place. However,
Then in the presence of a catalyst, such as tetrabutyltin or tetrabisopropyltin,
Condensation polymerization was carried out at about 140C and the reaction was determined by the change of viscosity
Should be the end. The curing temperature of this kind of silicone modified resin is very low
To room temperature curing), excellent dielectric properties, good adhesion,
Better water resistance, moisture resistance, light retention and powder resistance.
