slide1
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
slide2
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
slide3
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
p chlorobenzotrifluoride pcbtf
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)
specialty glycol ethers
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

hdi triisocyanurate
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
specialty meth acrylates
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

polyethylene glycol monomethacrylate
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)
hydroxyethyl methacrylate acid phosphate
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
methacrylamide
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
isocyanatoethyl methacrylate moi
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
