KOWA AMERICAN CORP. IS A LEADING IMPORTER OF P-CHLOROBENZOTRIFLUORIDE (PCBTF), WHICH IS A VOC EXEMPT SOLVENT THAT HAS SIMILAR SOLVENT AND HANDLING PROPERTIES AS XYLENE AND AROMATIC 100. VERY WIDE SOLUBILITY PROFILE ALLOWS PCBTF TO BE USED AS A SOLVENT FOR ALMOST ALL COATING RESINS COMMERCIALLY AVAILABLE (SOLUBILITY PARAMETER = 8.6). COMPATIBLE WITH WIDE VARIETY OF OTHER CO-SOLVENTS. SLIGHTLY SLOWER EVAPORATION RATE (0.9) THAN BUTYL ACETATE (1.0)

HIGHLY STABLE STRUCTURE, LOW ACIDITY (3 PPM MAX.) AND WATER CONTENT (150 PPM MAX.) ALLOW PCBTF TO BE SAFELY USED IN HIGHLY REACTIVE ISOCYANATE OR EPOXY RESIN SYSTEMS.

PCBTF DRUMS ARE STOCKED IN CHICAGO AND NEW JERSEY. FULL TRUCKLOAD DRUM DELIVERIES OF PCBTF DIRECT FROM CHINA CAN BE ARRANGED FOR FURTHER COST SAVINGS.

PROPOSED VOC EXEMPT SOLVENTS

DIMETHYL CARBONATE - DMC

KOWA AMERICAN HAS APPLIED TO THE EPA TO HAVE DIMETHYL CARBONATE (DMC) APPROVED AS A VOC EXEMPT SOLVENT.

DMC APPLICATION LETTER

DMC HAS AN ULTRA LOW MIR VALUE, WHICH IS A CHEMICALSfS MIR MEANS THAT CAN BE USED IMMEDIATELY IN AEROSOL COATINGS IN CALIFORNIA. WE EXPECT THE EPA TO PRINT A PROPOSED RULE EXEMPTING DMC (ALONG WITH BTF& PC BELOW) IN THE FEDERAL REGISTER IN 2007.

DIMETHYL CARBONATE IS A FAST EVAPORATING (E. R. = 3.22) POLAR SOLVENT WITH A LOW TOXICITY, METHANOL LIKE ODOR. GOOD SUBSTITUTE FOR ACETONE, METHYL ACETATE, T-BUTYL ACETATE, ISOPROPANOL AND MEK. SOLUBILITY PARAMETER = 20.3, FLASHPOINT 63o F (17o C), BOILING POINT 195oF (90oC)

BENZOTRIFLUORIDE - (BTF)

BTF IS ANOTHER SOLVENT KOWA AMERICAN IS REQUESTING TO THE EPA FOR VOC EXEMPTION. BTF HAS SIMILAR SOLVENCY AND EVAPORATION RATES TO TOLUENE. USING COMBINATIONS OF BTF WITH PCBTF SHOULD ALLOW A WIDE RANGE SOLVENT PROPERTIES TO BE OBTAINED.

FAST EVAPORATING (E.R. = 2.8) AROMATIC SOLVENT, SOLUBILITY PARAMETER = 7.9 FLASHPOINT 54o F, KAURI BUTANOL = 4

PROPYLENE CARBONATE

THIS PROPOSED VOC EXEMPT SOLVENT HAS A VERY SLOW EVAPORATION RATE, WHICH LIMITS ITS USE AS A TRADITIONAL SOLVENT.
