Superior Vinyl Ester Resin Grade I
Ecmalon 9921 is Epoxy Novolak based vinyl ester resin. Its resistance too many chemicals, oxidising acids and solvents is superior to that of bisphenol epoxy vinylesters, especially at elevated temperatures. Epoxy Novolak vinyl esters are particularly recommended for use in Chlor-alkali industry.
Ecmalon 9921 combines corrosion resistance with superior retention of properties at elevated temperatures.
The Resin properties and formulation are similar to Derakane 470 –36.
Liquid Resin Properties
Liquid resin properties are tested in accordance with the procedures described in IS6746-1994 and the values can vary within the tolerances mentioned therein.
