Applications
Polyester Coatings SAA-100 can be reacted with various fatty and dibasic acids to
yield polyester coatings with excellent detergent, stain and hydrolytic resistance. End
use markets for polyester coatings based on SAA-100 include appliance finishes, coil
coatings and general purpose baking enamels. Due to the broad compatibility of SAA-
100, it may be used in both water-based and high solids formulations.
Alkyd Coatings Fatty acid esters derived from SAA-100 and alkyds are components of
paints and finishes which are characterized by excellent leveling, wet and dry adhesion,
color acceptance, chemical resistance and durability. Primary end uses include wood
finishes, industrial maintenance paints, floor paints and latex house paints. Uralkycls
may be formed by sequentially reacting SAA-100 with alkyds and isocyanates. Finishes
containing SAA-100 based uralkyds have properties analogous to SAA-100 based
alkyds with the added benefit of faster drying time. SAA-100 based alkyds, modified with
maleic anhydride, yield coatings with superior corrosion resistance and fast drying times.
Maleic-modified alkyds, therefore, are used generally as primers for industrial
equipment, automobiles and farm machinery.
Urethane Coatings The hydroxyl content of SAA-100 allows the product to function as a
resinous polyol in urethane applications. When properly formulated with other polyols,
solvents and aliphatic isocyanates, SAA-100 improves weatherability, hardness and
chemical resistance in urethane coatings. The extent of these improvements is directly
proportional to the amount of SAA-100 incorporated in the coating.
Hard Resin Additive Being a hard, thermoplastic material which is compatible with a
wide variety of coreactants, SAA-100 can be used as a hard replacement for part of the
vehicle solids in a coatings formulation. When used in this way, SAA increases
hardness, gloss and print resistance of many systems including overprint varnishes. It
also improves resistance to condensing humidity, salt fog, detergent and stains.
