Epotec YDF 170 is general-purpose unmodified low viscosity diglycidyl ether of bisphenol-F. In addition to offering advantage in terms low viscosity, epotec YDF 170 provides better chemical resistance & flexibility when compared to similar bisphenol-A based liquid resin.
Epotec YDF 170 is compatible with all common epoxy resins in all ratios. A blend of epotec YDF 170 with bisphenol-A based liquid resin has better resistance to crystallization compared to unmodified base resins. Blending of epotec YDF 170 into std. bis-A based liquid epoxy resin brings down viscosity without affecting performance parameters unlike reactive diluent modified resin that affects mechanical, chemical and thermal resistance of the system.

Applications

• Solvent based, high solids and solvent free coatings
• Adhesives
• Civil engineering and construction industry
• Automotive coatings
• Coil coatings
• Marine and Industrial protective coatings
• Tooling, potting, casting and molding compounds
• Composites

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 YD 904 is a medium molecular weight solid epoxy resin for powder coatings requiring higher flexibility and toughness. This product is also suitable for making epoxy ester resins by reacting with fatty acids in appropriate quantity for which an esterification catalyst needs to be employed. Epotec YD 904 is also employed to produce functional powder coatings by combining with appropriate curing agent.
