A fiber mat for use in a building material, comprising:
- a plurality of glass fibers;
- and
- a fixative composition comprising a fiber binder and between about 0.05 wt.% and about 20 wt.% binder modifier, based on the weight of the binder, wherein the binder modifier comprises a hydrophobically modified acrylic swellable emulsion.
A process of making a fiber mat for use in a building material, said process comprising the steps of:
- (a) forming an aqueous fiber slurry;
- (b) removing water from the fiber slurry to form a wet fiber mat;
- (c) saturating the wet fiber mat with an aqueous solution of a fiber binder;
- (d) spraying the wet fiber mat with a binder modifier comprising an acrylic binder modifier, and
- (e) drying and curing the wet fiber mat to form a fiber mat product.
2 more elements
A fiber mat for use in a building material, said fiber mat comprising:
- 55 wt. % to 98 wt. % of fibers;
- 5 wt. % to 30 wt. % of a fiber binder comprising a urea/formaldehyde binder, a phenol formaldehyde binder, or a melamine/formaldehyde binder;
- and
- 0.05-20 wt. % of a hydrophobically modified acrylic swellable emulsion of 14,000 molecular weight.
