STARTING POINT FORMULATIONS
TWO-COMPONENT PARQUET FLOORING
Chemical resistance, hardness and drying are important properties for two-component
parquet flooring formulations.

Commercial, medium-Tg acrylic resins do not always dry rapidly enough or give hard
enough coatings without further modification. Cellulose acetate butyrate resins (CABs) are
commonly used to improve the sandability and dry times. Unfortunately, CABs can
significantly increase the cost of the final formulation. SAA-103 was evaluated vs.
CA
TM
381-0.5 in the following formulation and was found to give improved properties at
lower cost. The formulations were adjusted to maintain a constant isocyanate index.

SAA 103 decreased the solution viscosity (VOCs) and increased the gloss significantly. A
significant improvement in chemical resistance and abrasion resistance versus the CAB-
formulation occurred, due to the higher crosslink density of SAA resinous polyols.
