Bis-Phenol A Alkoxylates

BPA Propoxylate

BPA Ethoxylate

EO or PO Distribution Alkoxylated products always have a Poisson distribution Catalysis and/or reaction temperature can help control distribution

Uniqema’s Process Sophisticated post-treatment technique Low acid number Gardner color consistently at 1 or below Very low ion content (Na/K/P) Tight distribution

Features of BPA Alkoxylates Hydroxyl termination for use as a resin or a resin intermediate Aromatic moiety for resistance, adhesion and toughness Free rotation of methyl groups between aromatic groups for flexibility Limitless variations in size of EO, PO or EO/PO chains

Benefits of Using BPA Alkoxylates Corrosion resistance Chemical and moisture resistance Flexibility Toughness/hardness Improved adhesion Tg variation to meet final product needs

Current Uses Unsaturated polyester resins for fiberglass reinforcement, glass sizing and corrosion resistance Use PO derivatives from 2.0 to 16.0 Provide moisture and chemical resistance, adhesion, corrosion resistance Toner resins Use EO and PO derivatives 2.0 - 2.2 Control of Tg (glass transition temperature)

Current Uses Electodeposition coatings Radiation curable monomers Use 6.0 EO derivative Provides hardness for stone resistance and adhesion Radiation curable monomers Use EO derivatives from 2.2 to 30 moles Provide resistances, hardness/flexibility and adhesion

Current Uses Urethane foam and adhesives Use various EO and PO derivatives Provide adhesion to metal

Effect of BPAA in metal coating polyester system Polyester melamine system solvent based building blocks used Neopentylglycol, Hexanediol, Adipic acid, Isophtalic acid, Terephtalic acid Hexanediol and Neopentylglycol were used as reference and partially replaced with BPAA

Performance testing Hardness Some applications require both properties König Hardness represents the visco-elastic behaviour of a coating Buchholz Hardness represents deformation elasticity, i.e. a kind of recoverability (nail test), required for metal coating in particular Some applications require both properties
