COIM FILCO® 309 Film Former for Glass Fiber Sizes

 

Subcategory: Additive/Filler for Polymer; Thermoplastic

Material Notes:
Description: Film Former for Glass Fiber Sizes
General Information: COIM has developed a range of polyesters for the treatment of glass fiber. These polyesters come in powder and emulsion form and are collectively known as FILCO®. The products in the FILCO® line serve to size glass fiber, to optimize the mechanical characteristics of the fiber, or to bind the fibers for the production of mat.
Typical Physical and Chemical Characteristics:

  • Filco 309 is an epoxy resin in non-ionic water emulsion
  • pure epoxy resin
  • epoxy equivalent ~240
  • narrow particle size distribution
  • hydrolysis and sedimentation stability from pH 2 to 12 min. 48 h
  • good shelf life
  • high mechanical shear stability of the diluted emulsion

Characteristics of the dried film:
  • clear
  • tacky film
  • compatible with unsaturated polyester, epoxy, phenolic matrices
  • quickly soluble in styrene

Applications: Filco 309 is suggested as a film former for glass fiber sizes for:
  • filament winding roving
  • pultrusion roving
  • woven roving
