    Epoxy Resin(Diglycidyl ether of Bisphenol-A)

    Product Description

    RF-828 is a medium viscosity liquid epoxy resin produced from bisphenol A and epichlorohydrin. It is recognized as a standard form of epoxy resin and it contains no diluents.

    RF-828 provides good pigment wetting and good resistance to filler settling and a high level of mechanical and chemical resistance properties in the cured state. However, as an unmodified pure bisphenol A resin, RF-828 is prone to crystallize on storage, particularly in cold conditions.

    Diglycidyl ether of Bisphenol-A

    Application Direction

    Electrical and electronic industries (potting, casting, impregnating). Building and civil

    engineering industries (floorings, adhesives, mortars, grouts). Filament winding for

    composites solvent-free and high-solids coatings.


    Packing

    Normally packed in 240kg iron drum or 1,000kg IBC tank.


    Storage

    RF-828 should be stored in conditions so that moisture is excluded, preferably in the original containers kept tightly closed. Under these conditions and at normal temperatures the storage life should be at least one year. If RF-828 develops a haziness or crystallize on storage, this can be dispersed and the resin restored to its original condition by warming to 4550℃, with stirring.


    Handing precautions

    Product may cause skin and eye irritation. In cases of skin contact wash immediately with soap and water. For eyes, flush with plenty of water for 15 minutes and seek medical attention immediately.
