Best Finishes for Glass Fabrics

Fiberglass fabrics are highly versatile, enabling engineers to continually develop a variety of lightweight, budget-friendly products and improve upon existing items. More commonly known as “glass fabrics,” this type of material provides significant chemical resistance, high tensile strength, high thermal conductivity, and high thermal endurance. On average, glass fabrics can retain roughly 50% of their strength at temperatures as high as 700° F. Glass fabrics are available in a wide variety of weaves and finishes to suit many different needs.

Types of Glass Fabrics Finishes

Glass fabric often requires the application of a finish after weaving in order to preform as designed. Determining the best finish for a project will depend largely on the application and the end use performance criteria. With a wide variety of finishes to choose from, proper selection requires a detailed understanding of the manufacturing environment, chemistries used in the process and end use.

Starting with greige fabric the following are a few examples of some of the most common JPS finishes:

  • Caramelized/CS-210. Loom state fabric; partially volatized.
  • Heat Cleaned/CS-112. Fully heat cleaned fabric removing organics.
  • CS-767. Highly versatile, this finish features optimal wetting characteristics and functions well with polyimide, epoxy, and cyanate ester.
  • A-1100. This silane finish is recommended for phenolic and epoxy applications.
  • A-1100S. Like A-1100, A-1100S works well with phenolic, epoxy, applications but is designed as a softer finish for hand layup.
  • 9837. This vinyl functional silane finish pairs well with vinyl ester and polyester. The most common finish for our Astroquartz fabrics.
  • Great White (S-912). Designed for polyester recreational applications, this finish offers ideal clarity when used in building surf and paddle boards.
  • Volan. Offers a green tint for polyester and epoxy applications.
