EPON™ Resin CS-377

 

 

Product Description

EPON™ Resin CS-377 is a 100% reactive intermediate viscosity liquid bisphenol-A based  epoxy resin modified with an aromatic glycidyl ether.  This resin is specially designed for applications requiring an intermediate viscosity and low volatility. It exhibits minimal property loss under a broad range of processing or exposure conditions.  This resin should be considered where improved handling is important for the formulated epoxy component.

 

 

Application Areas/Suggested Uses

  • Industrial floor toppings and grouts
  • High build glaze, sealer or gel coats
  • General purpose casting and wet process composites
  • Electrical encapsulation and potting compounds
  • Low VOC high solids coatings

 

Benefits

  • Intermediate viscosity
  • Low color
  • Similar viscosity and reduced crystallization compared to EPON Resin 826
  • Good chemical resistance

General Information

EPON™ CS-377 is an effective resin when cross-linked or hardened with appropriate curing agents and provides superior mechanical, adhesive, electrical, and chemical resistance properties. It is compatible with and can be cured or cross-linked with a variety of curing agents depending on properties desired in the finished product and the processing conditions employed.  For ambient cure coating applications, EPIKURE™ Curing Agent 3140, 3155, 3164 and 3175 are potential curing agent candidates.  For other applications, a wide range of EPIKURE 3200 series aliphatic amine and EPIKURE 3300 series cycloaliphatic amine curing agents are available.

 

EPON CS-377 can also be used to fabricate high strength fiber reinforced pipes and composites. The low viscosity of the resin provides rapid wet out of a wide range of reinforcing fibers including glass, graphite and aramid. High fiber loading with low void content can be achieved with this resin. The resulting structural composites have a high ratio of strength to weight which makes them suitable for applications ranging from sporting goods equipment to aerospace structural members. Potential curing agents include polymeric acids, anhydrides, phenolic resins, the EPIKURE 9500 series products and EPIKURE W.
