Abstract
Various embodiments of the present invention provide sizing compositions, fiber glass strands, cement boards, and other products incorporating fiber glass. In some embodiments, a sizing composition of the present invention comprises a starch, a nonionic lubricant, a silane comprising at least one amine and at least one aryl or arylene group, and an aminofunctional oligomeric siloxane.
Claims22
A sizing composition for glass fibers, comprising:
- a starch in an amount up to about 45 percent by weight on a total solids basis, wherein the starch comprises from about 10 to about 30 percent amylose based on starch weight;
- a nonionic lubricant;
- a silane comprising at least one secondary or tertiary amine and at least one aryl or arylene group;
- and
- an aminofunctional oligomeric siloxane in an amount of from about 2 to about 12 percent by weight of the sizing composition on a total solids basis, wherein the aminofunctional oligomeric siloxane comprises at least one alkyl group bonded to a first silicon atom and at least one amine bonded to a second silicon atom;
- wherein the ratio of silane to siloxane is from 0.4:1 to 7:1.
