Product Description
Eastman™ Methyl Acetate, High Purity is a fast evaporating, mild odor, active solvent that is used with a broad range of coating and ink resins. It is similar in performance to the regular grade of methyl acetate supplied by Eastman. However, Eastman™ Methyl Acetate, High Purity is a urethane grade (low water and alcohol content) solvent, making it useful in moisture sensitive paints such as 2-K polyurethane coatings. Because of its fast evaporation rate, this solvent is suitable for use in other applications where fast solvent release and quick dry-to-touch time are needed. Methyl acetate is exempt from regulation as a VOC under Federal law [40 CFR 51.100(s)]. It is a non-HAP, non-ODS, readily biodegradable solvent that can be used in blends to develop environmentally friendly cleaners.
