H acetate. Comparable evaporation rates. Du Pont DBE is a slow-evaporating solvent that can improve gloss and leveling, reduce orange peel and minimize solvent popping. Its evaporation rate increases more rapidly than other slow solvents as temperature increases. And at bakeoven temperatures the evaporation rate of Du Pont DBE is comparable to other solvents, as shown in the graph. 900U βοοΓ 700 μ 600h 50ok 400 300
COATING SOLVENTS Evaporation vs. Temperature
Low toxicity. No human health problems have been reported to date from the use of dibasic esters. Wide application. Du Pont DBE s solvency for many polymers accounts for its use in a wide range of coatings, both conventional and high-solids. These uses include steel and alu minum coil coatings, interior and exterior can coatings and in finishes for appliances and metal furniture. Du Pont DBE is also used as a solvent in automotive acrylic lacquer and enamel topcoats, urethane trim paints, and polyester and epoxy primers. Call toll free.
