Binder compositions are described that include a phenol, a urea compound, formaldehyde, and at least one cyclic urea-dialdehyde compound. The cyclic urea-dialdehyde compound forms crosslinking bonds between polymers of phenol-urea-formaldehyde when the binder composition is cured. Also described are methods of making fiberglass insulation products using the above-described binder compositions. The methods may include contacting the binder composition with glass fibers and forming an amalgam of the binder composition and the glass fibers. The amalgam may be heated to form mats of the glass fibers and binder. The mats may be processed into the fiberglass insulation products.

Disclosed are single component, stimuli-responsive adhesives that cure in response to an applied stimulus, including single component moisture-curable adhesives (e.g., moisture-curable (meth)acrylate/polyurethane hybrid adhesives). These adhesive compositions can combine the non-toxic, high strength properties of (meth)acrylate adhesives with the bonding characteristics of polyurethanes. The compositions described herein employ imitator systems which trigger polymerization/curing of the adhesive composition in response to a stimulus, such as ambient moisture, mild heat, and/or by physical stress. These strategies eliminate the need for mixing or an external energy stimulus to initiate curing. In this way, the benefits of polyurethane adhesive chemistry can be brought to the consumer market, in a system that is readily usable by the average individual.

A process for the stabilization of pigmented monomeric (meth)acrylate-based compositions include a stabilizer selected from sterically hindered aminoxyl radical compounds and a urea-aldehyde resin and the use of sterically hindered aminoxyl radical compounds for the stabilization of pigmented monomeric (meth)acrylate-based compositions in the presence of a urea-aldehyde resin.

The present invention provides modified urea formaldehyde (UF) resin binder compositions and mineral fiber mats having an emulsion polymer modifier comprising, in copolymerized form, from 5 to 25 wt. % of co polymerized carboxylic acid functional monomers. The emulsion polymers have a measured glass transition temperature (DSC) ranging from 40 C. to 70 C. and a large average particle size. Further, the emulsion polymers comprise less than 30% of the copolymerized acid in neutralized form and do not excessively thicken aqueous compositions containing them. The modified UF resin binder compositions enable good dilution stability in use and high tensile strength in products containing them.

The present invention relates to two-dimensional and three-dimensional shaped parts and composite materials made of popcorn and synthetic and/or natural binding agents which are cured in automatic moulding machines or similar pressing installations by means of radio wave technology or microwaves. By means of these technologies, lightweight, two-dimensional and three-dimensional shaped parts and composite materials can be produced for packaging, as interior and exterior parts (for example in automobile and mobile-home construction), shock absorbers, space-dividing elements, furniture, consumer goods, for the building trade of for heat insulation.
