  1. KOWA • Kowa American is the US offices of KOWA Corp in Japan • One of the largest privately held companies in Japan • Kowa produces pharmaceuticals, optical good, electroptical instruments, textiles and activated carbon

  2. KOWA • Kowa is a worldwide trading organization • Products include chemicals, textiles, floor tile, fashion accessories, sporting goods, shoes, and foodstuffs • Offices in New York, Los Angeles, Chile, Germany, Italy, China (5), and most Asian countries

  3. KOWA • Chemical trading division sells a wide variety of chemical products into the United States including • monomers • VOC exempt solvent PCBTF specialty glycols additives • viscosity modifiers • isocyanates • specialty intermediates

  4. p-Chlorobenzotrifluoride (PCBTF) • Only aromatic solvent that is VOC exempt. • Excellent solvency & diluent properties with almost all commercially available coating resins and co-solvents. (solubility parameter = 8.6) • PCBTF has low acidity ( < 3 ppm) and low moisture (< 150 ppm) and very stable structure for use in highly urethane and epoxy systems • Moderate flashpoint (43°C) and evaporation rate (.9) slightly less than Butyl Acetate (1.0)

  5. SPECIALTY GLYCOL ETHERS OVER 40 SPECIALTY GLYCOL ETHERS ETHERS BASED ON MEG, DiEG, TriEG, Poly EG, PG, DiPG AND TriPG Both mono-alkyl and dialkyl ethers available For coatings requiring solvents with unique balance of hydrophobic & hydrophilic nature for superior coalescent,evaporation and coupling properties

  6. HDI Triisocyanurate • Aliphatic Isocyanate for specialty urethane coatings to improve weatherability and durability • Available in trimer or triisocyanurate (100% solids) form for handling & environmental safety • New long term source to offset Lyondell’s recent USA market departure

  7. SPECIALTY (METH)ACRYLATES POLYETHYLENE GLYCOL DIMETHACRYLATES (n = 1 THRU 23 POLYETHYLENE GLYCOL DIACRYLATES (n = 4 THRU 14) METHOXYPOLYETHYLENE GLYCOL MONOMETHACRYLATES (n = 2 THRU 23) POLYPROPYLENE GLYCOL DI(METH)ACRYLATES (n = 7 OR 12) PHENOXY POLYETHYLENE GLYCOL ACRYLATES (n = 2 THRU 6) (METH)ACRYLOYL OXYETHYL SUCCINATE (OR MALEATES) POLYMERIZABLE SURFACTANTS & SPECIALTY CROSSLINKERS

  8. Polyethylene Glycol Monomethacrylate • Polymerizable surfactant • Polyethylene monomethacrylate for increasing hydrophilic properties in finished resins • Further crosslinking of pendant hydroxy group possible • Formed by ethoxylation of methacrylic acid, diester content increases with chain length (for low diester needs try the methoxy peg mono(meth)acrylates)

  9. Hydroxyethyl Methacrylate Acid Phosphate • Adhesion promoting monomer for metal and surfaces • Acid functionality can be used for crosslinking reactions • Under development is a 4-Hydroxybutyl analog for better compatibility with more organophilic monomers

  10. Methacrylamide • A low toxicity replacement for acylamide • Generally used as low volume co-monomer to modify a variety properties of different types of polymers including acrylic, acrylonitrile, styrene, VCM, VAM and butadiene based resins • Produces lower viscosity and less water soluble resins than acrylamide based resins

  11. Isocyanatoethyl Methacrylate (MOI) • UNIQUE DUAL FUNCTIONAL MONOMER • Can be used to produce a variety of isocyanate functional • Resins or oligomers with a methacrylic backbone • Can alternately be used to form specialty methacrylate functional monomers or oligomers • Above reactions can be undertaken in relatively clean manner with minimal side reactions or disruption of the other functional group

  12. Sulfonate Monomers • Sodium p-Styrene Sulfonate • Sold as white powder • Over 90 % purity • Soluble in water up to 22%

  13. Sodium Methallyl Sulfonate • Available as white crystaline flakes • Over 99% purity, Soluble in water, • Insoluble in organic solvents

  14. Sodium Allyl Sulfonate • White powder, 95% min. purity Sodium Vinyl Sulfonate • 25% aqueous solution, • Polymerizable surfactant

  15. Ethylene Glycol Monoallyl Ether Polyethylene Glycol Monoallyl Ether • Polymerizable surfactant and crosslinkable monomer for specialty applications • A VARIETY OF OTHER ALLYL ETHERS ARE ALSO AVAILABLE

  16. Monoalkyl Glycidyl Ethers • Wide variety of monoalkyl glycidyl ethers ranging in size from butyl (C4) to stearyl (C18) • Useful as epoxy diluents

  17. Diglycidyl Ethers • Ethylene glycol diglycidyl ether • Hexanediol diglycidyl ether • Triglycidyl ethers also available • Crosslinking agent & reactive diluents

  18. Allyl Acrylate • Specialty monomer for crosslinking applications • Raw material for synthesis of highly specialized functional monomers

  19. Monovinyl Ethers • Variety of Alkyl and hydroxy-alkyl functionalities • Primarily used in cationic curing Divinyl Ethers • Crosslinking and multifunctional monomers for cationic curing
