Abstract: The invention relates to an aldehyde based resin composition that has an ultralow formaldehyde (ULF) emission both on curing and from the final cured product and to the use thereof as a binder or adhesive for the manufacture of mineral wool (glass fibre and stone fibre) products, non-woven materials, wooden boards, plywood, coated materials and/or impregnated material products. The invention further relates to a process for the manufacture of the resin composition, to a sizing composition for use in mineral wool applications, to a sizing composition for use in saturation or impregnation applications, and to a curable aqueous composition for use in board and wood applications, comprising the aldehyde resin composition according to the invention.

Abstract: A phenol-formaldehyde resin, which can be obtained by alkalinically catalyzed condensation of phenol and formaldehyde in the presence of at least one salt of inorganic acids and by neutralization by means of an inorganic or organic acid following the condensation, wherein the production takes place with the addition of at least one compound of the formula R1—(CH2)n—R2, in which R1 and R2, independently of one another, stand for —C(O)R, —COOR, —CN, or —NO2, and R represents H or CH3, and n has the value of 1 or 2. Also disclosed are the production of such resins and their use as binders for mineral-fiber-based insulating products.

Abstract: The invention relates to a water dilutable resin composition including a resin that is a reaction product of an aldehyde and a hydroxyl-aromatic compound, the composition further including an amino compound comprising 2-6 amino groups and a sugar alcohol, wherein the resin has an initial molar ratio of aldehyde to hydroxyl-aromatic compound from 2.3 to 5.5, a ratio of resin to amino compound plus sugar alcohol of 45:55 to 70:30 parts by weight, a ratio of amino compound to resin between 20:80 and 50:50 parts by weight and a ratio of sugar alcohol to resin plus amino compound is between 5:95 and 30:70 parts by weight. The invention further relates to a process for the manufacture the resin composition, to the use of the resin composition as binder material for non-woven fibrous material, in particular insulation materials, and to a process for the manufacture of such insulation material.
