applications 1. Coil coating DBE can help to balance the volatilizing speed of the whole process and avoid the paint flim poppig or overbaking defects due to overspeed volatilization. DBE can endow the film with a smooth appearance, better toughness and post-deformability, and can also enhance the hiding power of the paint. 2. Stoving varnish industry DBE has particular volatility; when temperature increases, the volatilizing speed increases faster than that of other solvents, that is: volatilize slowly in the first half phase, and fast in the second phase, which benefits to the drying process. The solvent volatilization curve goes more smoothly, solvent volatilizes more equally, and is helpful to improve the levelling and gloss, and eliminate surface defects. 3. Metal decorating coating DBE could effectively replace isophorone and propylene glycol ether series solvents used in tins and container paint. The high solvency and low volatilizing rate helps the paint to gain better levelling, flexibility, adhesive.
