Novolake – high temperatures and chemical resistance

Novolak vinyl ester resins, such as Derakane 470, are designed for maximum thermal and chemical resistance. They are particularly suitable for use in contact with solvents, acids and oxidizing substances such as chlorine gas.

Due to their good toughness at high temperatures up to 170 degrees Celsius, they have also proven themselves excellently in flue gas applications.

The principle: Novolak vinyl esters, dissolved in styrene, also harden by copolymerization with the solvent crosslinked.

Epoxy resins – maximum resistant and high temperature resistant

The processing of our combination is highly demanding, so resin and hardener softeners, for example, must be preheated to a certain temperature. We process bisphenol-A-epichlorohydrin-epoxy resin with so-called aromatic amine curing.

With this combination, we achieve the best resistance to a variety of acids, alkalis, solvents or oils and oil products. Due to the high degree of crosslinking and the very dense molecular grid, our epoxy resin tubes and containers can also be used for liquid media at significantly higher temperatures.

Up to 130 degrees Celsius are possible (further details can also be found on the resistance list.)

The principle: The reaction agents are incorporated into the molecular grid by a polyaddition reaction. Unlike polyester or vinyl ester resins, we take care to strictly adhere to the stoichiometric equivalent. This is how we achieve the highest quality and consistency.
