Product description

Eastman Optifilm™ enhancer 400 is a low odor coalescent that is compatible with a variety of latex types and it does not contribute to the VOC content of paints. It is an efficient coalescent that aids in the development of latex paints that have a good balance of performance properties. Optifilm 400 delivers excellent film integrity, touch-up properties, and scrub resistance, even at the lowest VOCs content. Paints prepared with Optifilm 400 have also demonstrated good exterior durability after one year exposure. It can also be blended with other coalescents such as Eastman Texanol™ ester alcohol or Eastman EEH glycol ether to further optimize the balance of low VOC content and paint performance.

Optifilm 400 is compatible with solvent borne acrylic resins and improves the flexibility and adhesion of coatings based on these resins. This product is non-phthalate and is not listed as a HAP or on SARA 313.

*Based on independent lab testing of paint using ASTM D6886 with methyl palmitate as the GC marker compound.
