EPOTEC® TH 7525 is a medium viscosity reactive polyamide used as a curing agent for liquid or solution grade epoxy resins such as EPOTEC® YD 128 or EPOTEC® YD 011X-75 to produce room temperature curable thermoset coatings. Epotec TH 7525 is specially used in solvent based anti-corrosion coatings and shows compatibility with wide range of solvents normally used in epoxy based coatings. The reactivity of the product can be adjusted by blending with tertiary amine and the viscosity by other reactive polyamides. The coatings based on EPOTEC® TH 7525 shows good toughness and adhesion properties. Because of these properties, it finds use in various applications.

EPOTEC® TH 7334 is a low viscosity, low colour modified cycloaliphatic polyamine curing agent for use with liquid epoxy resins such as EPOTEC® YD 128 to produce solvent free room temperature curable thermoset coatings, floor toppings. When formulated appropriately with epoxy resin it gives clear, air free, glossy surfaces. It has high blush resistance under high humidity condition. It also provides resistance to variety of chemicals such as acids, alkalies, hydrocarbons and water.

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.

Epotec YD 134 is an unmodified semi-solid epoxy resin based on Bisphenol-A. At normal room temperature of 25°C this resin has high viscosity & has no or very little flowability. This resin has molecular weight higher than standard liquid epoxy resin epotec YD 128. Due to its viscous, semi-solid nature this resin is used, normally with solvents or applied at elevated temperature to induce the flow, mainly in adhesives & protective coatings. It can also be used to modify other epoxy resins to impart or improve the toughness, flexibility, adhesion etc.
