Product Description

In architectural coatings Eastman Optifilm™ enhancer 300 is an efficient, low odor, low toxicity coalescent for latex paints. Its broad compatibility, easy incorporation, and excellent hydrolytic stability allow its use in a wide range of latex types. Appropriate for many architectural applications, it is particularly suited for low odor flat and low sheen wall paints. The low odor performance of Eastman Optifilm™ 300 enhancer was evaluated in statistically designed experiments. The technical tip titled Reduce Dispersion Paint Odour Using Eastman Optifilm™ enhancer 300 below outlines the procedure used and the evaluation results.

The use of Eastman Optifilm™ enhancer 300 reduces formulated cost by allowing substantial reductions in associative thickeners. Greater than 25% reduction in associative thickener levels can be obtained without compromising rheology characteristics. For more details see the technical tip, Lower Coatings Costs With Texanol™ Ester Alcohol or Eastman Optifilm™ enhancer 300 below.

For industrial bake coatings, Eastman Optifilm™ enhancer 300 is an excellent retarder solvent, and is compatible with a variety of resin systems, making it useful over a wide range of application conditions and substrates. It compared favorably in tests versus a widely used retarder solvent in a polyester coil coating application. The results of this evaluation are discussed in the online technical tip entitled Eastman Retarder Solvent and Eastman Optifilm™ enhancer 300 for Industrial Bake Coatings.

With a boiling point of 281°C, (vapor pressure 0.0007 kPa @ 20°C), Eastman Optifilm™ enhancer 300 is not classified as a VOC according to European Union Decopaint Directive 2004/42/EC (commonly referred to as the Decopaint Directive); European Union Solvent Emissions Directive; and the China State Environmental Protection Agency. Due to its low toxicity and non-VOC status, Eastman Optifilm™ enhancer 300 has been awarded Green Label Type II certificate in China by the China Environmental United Certification Co. Ltd. (CEC), a wholly-owned subsidiary of the State Environmental Protection Administration of China (SEPA).
