SIZER FOR FIBER GLASS Russian patent published in 2009 - IPC C03C25/24 

FIELD: chemistry.

SUBSTANCE: sizer composition for fiber glass processing includes, wt %: extrusion tapioca starch 0.5-1.5; MAC-4 substance 1-3; dicyandiamide-formaldehyde resin (DCU) 1-2; acetic acid 0.01-0.02; the rest is water. Processing of fiber with sizer allows for good wetting properties of articles during further processing with binding compositions using organic solvents. Claimed sizer composition does not require sophisticated preparation technology, ensures sufficient processibility of further fiber glass processing, has low production cost, and improves labour environment significantly in manufacturing of continuous fiber glass.

EFFECT: sufficient processibility of further fiber glass processing, low production cost and improved labour environment in manufacturing of continuous fiber glass.
