Xylene Resin

Xylene resin

  • Straight types: Formed by bridged methylene linkage or ether linkage
  • Modified types: Modified by phenols, polyhydric alcohols, or other

[Improved features]

  • Control viscosity of various resins (decrease or increase), Good compatibility with various resins
  • Initial adhesion, Tackiness and Stickiness
  • Flexibility
  • Water, Moisture, Alkali, and Gasolin resistance
  • Dielectric property and electric insulation

[Target resins]

  • Epoxy resin, phenol resin, acrylic resin, unsaturated polyester resin, urethane resin, various rubbers (NR/CR/NBR, SBR, SIS, SBS, EPDM, etc.), chlorinated polyethylene, alkyd resin, etc.

Straight type

The basic structure of Straight type is a multimer composition formed by m-xylene by methylene linkage or ether linkage and a part of the edge is an OH-group (OH value: 20 to 40 mgKOH/g). Therefore, Straight type is excellent in compatibility with many synthetic resins and is used for improvement in performance of various resins.

a. Low-viscosity xylene resin

This is an environment-compatible modifier that is not a substance prohibited by VOC. This is the best suited as a modifier for various resins e.g. epoxy resin, phenol resin, unsaturated polyester resin, acrylic resin, urethane resin, and alkyd resin.

Grade Viscosity (mPa•s/25°C) Specific gravity (20°C) OH value (mgKOH/g)
Y-50 50 1.019 20
Y-100 100 1.029 25

[Additional features]

Epoxy resin coating
Flexibility, Leveling, Wettability, Mositure and Water resistance

b. Environment-friendly xylene resin

Y-300 features lower TVOC and lower heating loss in comparison with Y-50 and Y-100, and can be expected to be utilized for epoxy resin, acrylic resin as a modifier that has a low environmental burden because it discharges a small amount of outgas when it heated.
