December 2, YD-134 Standard Liquid type Epoxy

1 ISO-9001. ISO-14001. KUKDO. December 2, YD-134 Standard Liquid type Epoxy 2004. General Description Examples of its application are as follow : EPOKUKDO Epoxy Resin, YD-134 is a semisolid Epoxy Resin for the general adhesives, coatings and moldings. Formulation 1. YD-134 has good adhesion, excellent mechanical Resin Hardener properties and chemical resistance. Due to its excellent properties after curing, YD-134 is mainly recommended A(Adduct product) B. for the anti-corrosive industrial coating, marine paint, YD-134 YD-134 DETA civil engineering, coal tar Epoxy and various adhesives. Coal tar pitch DETA n-Butanol Due to its high viscosity, the various solution products Xylene Xylene with solvent, such as YD-134X80, can be used in Asbestos sec-Butanol applications.

2 YD-134 has higher EEW, so that it needs Silica less quantity of curatives and accelerators than Standard n-Butanol Liquid resin such as YD-128.

YD-134 DETA YD-134 1. Application of YD-134 coal tar Epoxy Resin Asbestos sec-Butanol DETA EPOKUKDO YD-134 resin modified with the coal tar is Aerosil Xylene used in the marine and concrete bath such as coating Xylene sec-Butanol materials.

3 Due to the coal tar, the water-proof property sec-Butanol specially becomes better. Coal tar Epoxy is suitable for the marine paints and coatings which need chemical resistance and anti-corrosion. In case they have some Formulation ratio problems with black color, it is better to use it for colorful (1) Resin base element 100 parts paints having chemical resistance and decoration.
