E-glass Yarn Sizing

Only the highest quality fibreglass yarns are used in Colan fabrics. We use two yarn suppliers, Saint-Gobain Vetrotex and PPG, two of the leaders in fibreglass yarn technology.



(High clear - Surfboard Yarn)

Saint-Gobain Vetrotex TD37C is a high clear yarn used in our range of high performance Surfboard Fabrics

TD37C is a pure plastic size with universal coupling agents (silanes) which is directly compatible with Epoxy, Polyester and Phenolic resins as well as PVC-plastisols.

Glass filament yarns sized with TD37C have excellent textile properties which support the production of different types of textile structures. Woven fabrics, tapes, braids, multiaxial fabrics, sleeves, complexes or knits can be directly impregnated with resins. Any de-sizing process is not recommended.

TD37C is an evolution of the well known TD22G size. The main film former of the TD22G size has been modified in order to reduce the risks of sticky deposits during the processing of the yarn. The chemical nature of the film former remains the same as well as other components of the size

TD37C yarns have the following advantages:

  • Reduction of deposits and fuzz
  • Improved process-ability
  • Lower friction coefficient
  • Easier impregnation with resins
  • Better characteristics of the composites
