EASTMAN AQ polymers differ chiefly in glass transition temperature (Tg) or softening point. The "dry" Tg of each polyester is indicated by its numerical designation. EASTMAN AQ 38D polymer has a Tg of 38. The "S" or "D" refers to the solid or dispersed form of the polymer. Flocculants Sealants Copolyester. Relatively high molecular weight, amorphous polyester dispersed directly in water without the assistance of organic cosolvents, surfactants, or amines. Used in sealants.
