Abstract: A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises a substantially unpolymerized acrylate and/or methacrylate primarily having no more than approximately six recurring moieties. The composition is either unpolymerized at the time of its application to the fiberglass or in the form of an oligomer. The curable composition is coated on fiberglass and thereafter is cured to form a secure binder. In a preferred embodiment the fiberglass is the form of building insulation. In other embodiments the product is a microglass-based substrate useful for as a printed circuit board, battery separator, filter stock, or reinforcement scrim.

Abstract: Provided is a fiberglass binder composition which comprises epoxidized oil and a multifunctional carboxylic acid or anhydride. The resultant binder provides minimal processing difficulties and a fiberglass product which exhibits minimal water absorption. The cure time of the binder is also exceptional.

Abstract: Glass fibers, particularly those prepared by flame attenuation, display excellent chemical resistance to both acids and moisture while being highly biosoluble at the same time. The glass compositions used to make the fibers consisting essentially of: 38-52 wt % SiO2, 8-17 wt % A1203, 7-17 wt % B203, 0-7 wt % RO, wherein R is Ca, Mg, in a combination thereof, 20-31 wt R120, wherein R1 is Na, K, or a combination thereof, and 0-2.5 wt % Li20, and has a Final Aged Tensile Value of at least 3000; a HTV of 1700° F. or less and a liquidus temperature at least 200° F. lower than HTV.
