Abstract
A glass yarn sizing composition consisting of a solution having a viscosity of at most 400 cP and including less than 5 wt. % of solvent and at least one basic heat-polymerisable system which includes at least 60 wt. % of components having a molecular weight of less than 750, and at least 60 wt. % of a mixture of one or more components having at least one epoxy reactive function, and one or more components having at least one (preferably primary or secondary) amine reactive function, wherein the amount of components having at least one amine reactive function represents at least 6 wt. % of the composition. A method using said composition, and the resulting yarns coated with said composition, are also disclosed.
