Abstract
Plastisol compositions are provided including a polymeric resin in the form of particulates dispersed within a plasticizer and one or more hydrolyzable organosilicon compounds. A suitable solvent system can be utilized in the plastisol compositions. Also provided are inorganic fibers, and particularly reinforcing scrims, that are at least partially coated with a plastisol composition including one or more hydrolyzable organosilicon compounds. Cementitious boards reinforced with plastisol coated inorganic fibers, such as mesh scrims, are also provided.

A coated fiber, comprising:
- an inorganic fiber indirectly or directly at least partially coated with a plastisol composition, said plastisol composition comprising (i) a plasticizer;
- (ii) a polymeric resin;
- and (iii) one or more hydrolyzable organosilicon compounds (“HOC”), wherein the one or more hydrolysable organosilicon compounds comprise a crosslinked amine functional dialkylpolysiloxane.
A coated fiber, comprising:
- an inorganic fiber indirectly or directly at least partially coated with a plastisol composition, said plastisol composition comprising (i) a plasticizer;
- (ii) a polymeric resin;
- and (iii) one or more hydrolyzable organosilicon compounds (“HOC”), wherein the one or more hydrolysable organosilicon compounds comprise a cross-linkableamine functional dialkylpolysiloxane, wherein the one or more HOC comprises an alkoxy aminofunctional dialkylpolysiloxane selected from the following:
- wherein R1 is an alkyl group;
- R2 is a monovalent hydrocarbon group having from 1 to 20 carbon atoms or a halogen-substituted group thereof;
- and Z is an amino-substituted monovalent hydrocarbon group represented by the formula:
- R2—(NH—R3)a—NH—R4
- wherein R3 is a divalent hydrocarbon group having from 1 to 5 carbon atoms;
- R4 is a hydrogen atom, a monovalent hydrocarbon group having from 1 to 20 carbon atoms, or a halogen-substituted group thereof;
- a has a value of 0, 1, 2 or 3;
- and x and y are each positive integers.
