1 New DOL & Oxetane Monomers from Osaka Organic Chemicals Co., Ltd. San Esters Corporation

2 OSAKA ORGANIC CHEMICAL  Research oriented monomer manufacturer (over 33% of staff is in R&D functions)  Actively developing new monomers for the radcure and conventional cure industries  Specializing in difficult synthesis and distillation processes  Custom manufacturing inquiries welcome (or for special purity needs)

3 NEW MONOMERS FROM OOC  DOL Series of Monomers Dioxolane functional Acrylates & Methacrlyates Designed as high diluency monomers with low skin irritation A selection of side groups (Alkyl, Cycloaliphatic, Aryl) allows optimum compatibility with different UV cure systems

4 MEDOL 10 & MIBDOL 10  Low viscosity diluent acrylate monomers as replacements for Tetrahydrofurfuryl acrylate (THFA)  Very low skin irritation, Below 1.3 P.I.I. (Draize) compared to THFA’s severe irritation, P.I.I.>5.0  Much less odor than THFA  Slower evaporation rates than THFA (approx. 50% slower)

5 Medol 10, 30 VISCOSITY (mPas) P.I.I. (DRAIZE) DENSITY SURFACE TENSION (DYNES/CM) Tg -7

6 Mibdol 10, 30 VISCOSITY (mPAs) P.I.I. (DRAIZE) DENSITY SURFACE TENSION (dynes/cm) Tg (°C) -19

7 Chdol -10, 30 VISCOSITY (mPas) P.I.I (DRAIZE).55 - DENSITY SURFACE TENSION (dynes/cm) Tg (°C) 22 -

8 MMDOL 30 VISCOSITY (mPas) 4.1 DENSITY SURFACE TENSION 31.1

13 Formulation  Sample : Base resin : Irg907 : DETX = 50 : 50 : 3 : 1  Base resin = Viscoat 540: Viscoat 360 = 4:1

14 DOL MONOMERS  Newly developed chemistry  Samples of Medol 10 and Mibdol 10 available now  Japanese Miti low volume exemption pending for Medol 10  TSCA, Einecs applications to be based on commercial interest

15 OXETANE (METH)ACRYLATE  Newly developed low viscosity monomers  Potential for dual cure reactions  Form Oxetane functional oligomers, resins or primer films by free radical reaction  Catonic cure or crosslink as second step
