Sucrose benzoate SB: softening 95–101 °C

Benzoin and MIRATE Epoxy Diluent

Miwon benzoin serves as an anti-crater agent and as an intermediate for pharmaceutical compounds. MIRATE BGE butyl glycidyl ether is a diluent that reduces the viscosity of epoxy resins. Photoinitiator production started in 1983 at the Banwol plant.

Benzoin: purity 99.5% min.
Benzoin: anti-crater agent
MIRATE BGE: lowers epoxy viscosity
Photoinitiators: produced since 1983

Reactive Diluent for Viscosity and Crosslink Density

The diluent is chosen by functionality and by viscosity at 25 °C. Monofunctional IBOA M1140 (8 mPa·s) and THFA M150 (3 mPa·s) lower viscosity and raise adhesion but add little to crosslink density.

The manufacturer notes good cutting power for the diacrylates HDDA M200 (6 mPa·s) and TPGDA M220 (13 mPa·s). TMPTA M300 (99 mPa·s) and DPHA M600 (5,782 mPa·s) raise film hardness and scratch resistance.

Ethoxylated triacrylates such as TMP(EO)6TA M3160 (92 mPa·s) give a more flexible and hydrophilic film.

Oligomer for the Required Film Properties

The oligomer sets the cured film properties. Aliphatic urethane acrylates such as PU2100 give elongation and low yellowing, the aromatic PU2900 (55,000 mPa·s) gives gloss and toughness.

Bisphenol A epoxy acrylates such as PE2120A give high pendulum hardness and gloss, the bio-based polyester acrylate PS6430 gives pigment wetting in inks.

The manufacturer lists oligomer viscosity at 25, 60 or 65.5 °C: PE2120C has 1,100 mPa·s at 60 °C, EA2280 3,000 mPa·s at 65.5 °C. Grades are compared at one temperature only, and the TDS is requested for formulation work.

LED Curing and Amine Synergists

Varnishes cured by LED need more reactivity than standard UV systems: the manufacturer reports demand for LED curable overprint varnishes to replace UV curable ones. The polyester acrylate PS6180 is listed with high UV LED reactivity.

Acrylated amine synergists such as AS2010 act as co-initiators, and AS5142 shows no surface migration of amine.

For flexible packaging the manufacturer offers low residue products, a polymeric photoinitiator and BPA free oligomers; for inks, grades free of TMPTA, PETIA and organotin, low VOC and bio-based products.

Selection by Application

For printed circuit boards the manufacturer offers monomers and oligomers for dry film resists, solder masks and conformal coatings; the alkali strippable polyester acrylate SC6632 carries acid functionality.

Displays use grades with a wide range of refractive indexes, 3D printing covers SLA, DLP and 3D inkjet. Adhesives include UV curable, anaerobic, structural and pressure sensitive types.

Phosphate methacrylate SC1400 improves adhesion to metal, glass and plastic, the inert resin S5380 serves UV adhesion primers on polyolefins. Flooring and furniture use urethane, polyester and epoxy acrylates; automotive uses include headlamp coatings and interior plastics.
