Abstract
A sizing composition which is useful for coating glass strands contains a solution having a solvent content of less than 5% by weight. The solution contains at least 45% by weight of components capable of curing. At least 40% of the components capable of curing have a molecular mass of between 750 and 5000. The components capable of curing contain at least one mixture containing a) one or more components having at least one acrylic reactive functional group and/or methacrylic reactive functional group, and b) one or more components having at least one primary amine reactive functional group and/or secondary amine reactive functional group.
