Product Description

DER 331 EPOXY resin

 

Product Description

 

D.E.R. 331 Description
D.E.R.™  331™  Liquid  Epoxy  Resin  is  a  liquid reaction product  of  epichlorohydrin  and bisphenol A.A  wide  variety  of  curing  agents   is  available  to  cure   liquid  epoxy   resins  at  ambient conditions. The most frequently used are aliphatic polyamines, polyamides, amidoamines, cycloaliphatic amines and modified versions of these curing agents. Curing may also be done  at  an  elevated  temperature  to  improve  selected  properties  such  as  chemical resistance  and  glass transition temperature.  If  anhydride  or  catalytic  curing  agents  are employed, elevated temperature cures are necessary and long post-cures are required to develop full end properties.

 

D.E.R. 331 Typical Applications
This product is suitable for use in applications such as:
•   Adhesives
•   Casting and Tooling
•   Civil Engineering
•   Composites
•   Automotive Coatings
•   Can and Coil Coatings
•    Marine and Protective Coatings
•    Photocure Industrial Coatings
•    Potting and Encapsulation

 

 

D.E.R. 331 Safety and handling
The Dow Chemical Company provides its customers with a product specific Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) to cover potential  health effects,  safe handling, storage, use and disposal information. Dow strongly encourages its customers to review the MSDS or SDS on its products and other materials prior to their use.

This liquid epoxy resin is supplied in bulk, in 1000 kg intermediate bulk containers or in 240 kg  tight-head  drums.  The  resin  should  be  stored  in  a  dry  place  in its  original closed packaging. This lowviscosity epoxy resin should retain its chemical properties for a period of at least 24 months. For further handling information consult the Dow brochure entitled, DOW Epoxy Resins Product Stewardship Manual, Safe Handling and Storage,  Form No.  296- 00312 and the technical bulletin, Product Coding, Shelf-life and Storage Stability, Form No.  296-01657.

D.E.R.™  331™  Liquid Epoxy Resin can crystallize. This reversible,  physical  phenomena can be greatly avoided by storing the resin at temperatures not below25ºC. For additional information, consult the technical bulletin, Crystallization of Liquid Epoxy Resins,  Form No. 296-01652.
