Binder for improved glass fiber mats

摘要

A glass fiber mat having improved strength and fiber wettability is provided by incorporation of a critical amount of between 1% and 6% by weight (solids) of a carboxylated styrene-butadiene latex having a pH between about 5 and about 8.5, a glass transition temperature (Tg) less than 25 DEG C. and a surface tension less than 50 dynes/cm, and 94% and 99% by weight (solids) of a urea-formaldehyde resin solution having a pH of from about 6.5 to about 8.5.
