CPC classification number: D21H19/12 , C08G12/12 , C08G12/40 , C08L61/24 , C08L61/32 , C08L33/08 , C08L33/10 , C08L33/14 , C08L33/02
Abstract: The present invention provides aqueous urea formaldehyde resin (UF resin) compositions having a pH or 7.0 or more, preferably, 8.5 or more, and comprising the UF resin modified with from 2.5 to 15 wt. %, of at least one ammonia or volatile amine neutralized carboxylic acid group containing solution polymer or alkali soluble emulsion polymer modifier, based on total UF resin and polymer solids, wherein the polymer modifier is the reaction product of 30 to 100 wt. % of methacrylic acid, acrylic acid, maleic anhydride, a salt thereof, or mixtures thereof, wherein the solution polymer has a weight average molecular weight of from 2,000 to 16,000 and the alkali soluble emulsion copolymer has a weight average molecular weight of from 1,500 to 20,000. The compositions enable the provision of untreated glass mats having improved wet web strength to prevent mat breakage in process.
