EPOTEC® YD 515 is a bisphenol-A liquid epoxy resin modified with reactive diluent. This resin offers lower viscosity & lower surface tension. Both these properties are advantageous while formulating. The low viscosity improves the cost effectiveness by increasing filler loading & the low surface tension improves adhesion by better substrate wetting, it also helps in better pigment wetting and thereby improve the pigment dispersion and stability. A wide variety of curing agents are available to cure this liquid epoxy resin at ambient conditions and also at elevated temperature. Sometimes systems based on this grade are post cured to improve certain characteristics such as glass transition temperature and chemical resistance.

Epotec YDF 172 is a liquid epoxy resin reaction product of Bisphenol F and epichlorohydrin. This resin provides less crystallization tendency compared with standard liquid resin.

Epotec RD 113 is a low viscosity trifunctional epoxy reactive diluent based on trimethylol propane. Being trifunctional epotec RD 113 provides excellent cross link density in the cured mass. The higher cross link density helps in improving the chemical resistance of the formulations based on conventional bis-A epoxy resins. Epotec RD 113 also has minimum effect on the HDT and glass transition temperature of the cured mass.

Epotec YD 128 is an unmodified liquid epoxy resin with medium viscosity produced from bisphenol-A and epichlorohydrin. This is a standard liquid epoxy resin and a wide variety of curing agents are available to cure this liquid epoxy resin at ambient conditions and also at elevated temperature. When cured with appropriate hardener, epotec YD 128 gives excellent mechanical, chemical, electrical and adhesion properties. Because of these properties it finds use in various applications.
