摘要： A method of making a glass mat includes providing an assembly of glass fibers, applying a binder composition to the assembly of glass fibers, wherein the binder includes an organic resin, and curing the binder composition while dimensionally constraining the assembly of glass fibers. Dimensional constraining includes directly contacting a first major surface and a second major surface of the assembly of glass fibers between two substantially parallel surfaces. Further provided is a glass mat that includes an assembly of glass fibers, wherein the assembly of glass fibers are substantially randomly oriented with a tensile anisotropy of less than about 6 in any two directions. The glass mat has a decreased surface roughness and a decreased caliper compared to an equivalent glass mat having an assembly of naturally packed glass fibers with an equivalent fiber diameter size.

摘要： A method for producing stable urea-formaldehyde polymers which have reduced aldehyde vapor emissions during their production and use is disclosed, such urea-formaldehyde polymers particularly useful in the production of urea-formaldehyde insulating foam and as adhesives in the production of plywood and particleboard. An alkali or alkaline earth metal borohydride is added to the urea-formaldehyde resin solution prior to or during cure thereof. The boroydride reacts with free formaldehyde in the resin solution or any free formaldehyde subsequently generated in the resin due to hydrolytic break down. The amount of borohydride added the resin solution should be sufficient to reduce the emission of free formaldehyde therefrom.

摘要： A process for producing stable urea-aldehyde polymers with high structural strength from two storable liquid ingredients. In this process, partially cured liquid urea-formaldehyde resin is reacted with an aqueous cross-linking solution comprising one or more alkyl or aryl dialdehydes containing two to eight molecular carbons and the hydrogen ion concentration needed to catalyze the completion of the reaction of the dialdehydes and the urea-formaldehyde. The process for producing urea-aldehyde polymers, having improved structural strength and reduced aldehyde vapor emission during their production and prolonged use, is especially effective for manufacturing products for the building industry, such as urea-aldehyde insulating foam, wood-filled particle board, and plywood. The increased polymer strength and the elimination of the hazardous and objectionable aldehyde odor is achieved by maintaining the molecular ratio of total aldehyde moieties to urea to about 1.8 and the molecular ratio of the aldehyde moieties in the dialdehydes to those in formaldehyde at about 0.2. The process requires that the dialdehydes be substantially contained in the cross-linking solution for system storability and long term reactivity. The hydrogen ion concentration required in the cross-linking solution is represented by a pH of about 3 and may be achieved by addition of water soluble acid or by heating the mixture and converting some aldehydes to acids.

摘要： Hydrophilic floral display foam blocks are prepared from frothed urea-formaldehyde, and wherein the urea-formaldehyde contains an alkyl-aryl sulfonate, and wherein the alkyl-aryl sulfonate has been exposed to an aqueous solution of a quaternary ammonium salt in an amount sufficient to provide at least equal molar concentrations of the quaternary ammonium salt to the alkyl-aryl sulfonate present in the foam. The urea-formaldehyde foam may also contain quantities of sodium molybdate to enhance the stability and lifetime of cut flowers retained in the foam material. Also, the urea-formaldehyde foam may contain starch to help suppress the free formaldehyde odor and help increase the biodegradability of the cured foam. The resulting foam is hydrophilic in nature, and hence is readily wetted, with the hydrophilic characteristic not adversely affecting the life of cut flowers retained therein.
