Yields lightweight, thixotropic filling compouds

  • For epoxy, polyester, and polyurethane resins

Manufacture of light, nonrun adhesive, pourable moulding compound and coupler coatings for mould construction, using a mixture of 50 volume percent glass fibre cuttings and 50 volume percent cotton flocks. Cotton flocks are use for enhanced dimensional stability in moulded products, increased impact and abrasion resistance. Good adhesion to epoxy, polyester, and polyurethane resins as well as to rubber compounds. Resistance to many chemicals and alkalines. Low cost. Low density: 4.5 litre Cotton flocks = 1 kg (0.22 g/cm³)

White flocks, fibre length: approx. 350 µm (typical 150–500 µm), fibre width: 10–25 µm (1–3 Denier), specific gravity: 1.5 g/cm³, melting charakteristic: chars at 250 °F (120 °C), decomposes at: 300 °F (150 °C), tensile strenght: up to 120,000 psi (ca. 800 N/mm²). Insoluble in Acetone, DMF or 40 % NaOH, water uptake: approx. 0.3 g per g cotton flocks.

The volume details are intended to assist in judging the amount supplied. These details refer to the loose bulk amount. The contents may become compressed during transport or storage.

Safety data sheet:
Safety data sheets are required on the basis of the REACH Regulation for dangerous substances and mixtures. Cotton flocks are not dangerous or a substance or mixture within the meaning of REACH. It is a product for which, by definition, no safety data sheet can be provided.
