Product Description

Eastman™ n-Propyl Propionate is a non-HAP, medium evaporating, urethane grade solvent that provides good activity for most coating resins. Its good activity yields efficient resin viscosity reduction that enables the development of lower VOC coatings. Eastman n-propyl propionate linear structure allows fast diffusion through coatings and printing inks films. It has lower odor than solvents of similar volatility.

Many resins are letdown in a solvent thinning tank to make handling, storing, and shipping easier. Eastman™ n-Propyl Propionate is useful as a letdown solvent because of its low volatility, good solvent activity, and urethane grade quality. Since this product is not a HAP, it is a good choice when formulating solvent blend replacements for toluene and xylene in coating applications such as high-solids thermoset enamels. Its high electrical resistivity is beneficial in optimizing transfer efficiency in coatings applied via electrostatic spray equipment.
