EPON™ Resin 872-X-75

 

 

Product Description

EPON™ Resin 872-X-75 is a 75% by weight solution of EPON 872 in xylene. EPON 872 is a chemically-modified BPA based epoxy resin that is semi-solid at room temperature. Systems using EPON Resin 872-X-75 can be combined with other EPON Resins, HELOXY™ Modifiers, or used as the sole resin to provide varying degrees of flexibility and toughness. EPON Resin 872-X-75 can be used with most curing agent types. EPON Resin 872-X-75 provides cured resin toughness and flexibility in comparison to liquid grade BPA epoxies, but reduces elevated temperature performance. EPON Resin 872-X-75 is especially useful in applications requiring extra thermal shock or impact resistance.

 

Benefits

  • May be blended with other epoxy resins.
  • Imparts good water resistance.
  • Low viscosity epoxy resin solution in xylene.
  • Designed for solvent-based coating systems.
  • Improved toughness and flexibility relative to unmodified liquid epoxies.

Processing/How to use

 

General Information

 

A wide variety of curing agents can be used with EPON Resin 872-X-75; such as, aliphatic amines, amidoamines, amine adducts, polyamides, and cycloaliphatic amines.  EPON Resin 872-X-75 solution is especially suitable for the formulation of coatings due to its inherent toughness and flexibility. Other end-use applications are also possible.

 

In coating applications, EPON Resin 872-X-75 may be initially incompatible with the selected curing agent. As the chemical reaction between the two proceeds, compatibility with each other will develop with time. Applying the system too quickly after mixing can result in “blushing” or other film defects. Blushing can be prevented by using an induction period to allow compatibility to develop before applying the coating. Required induction periods will differ with each curing agent but can range from 0 to 60 minutes.
