Intumescent laminate with high heat transfer resistance composed of a glass-fiber web or glass-fiber fabric each of which has been coated with a four-component intumescent composition comprising a) a phosphate compound, b) a melamine compound, c) a polyol and d) an inorganic framework-forming compound.

Intumescent laminates with high heat transfer resistance

Copolymers which are obtainable by reacting acrylic monomers with monomers of the following formula:

Acrylic copolymers

Method of conditioning soils, in which copolymers which are composed of acrylamide and/or methacrylamide, a sulphonyl-containing, substituted acrylamide or methacrylamide, a multi-functional, water-soluble vinyl compound and, if appropriate, carboxyl-containing comonomers are added to the soils as soil conditioners.

Soil conditioners

Process for the continuous drying of hydrophilic polymer gels in a cylindrical dryer with a high speed rotor which conveys the material to be dried through the dryer and prevents agglomeration.

Process for the continuous drying of hydrophilic polymer gels

Use of salts of water-soluble naphthalenesulfonic acid formaldehyde condensates having a molar formaldehyde/naphthalenesulfonic acid ratio of 1.2:1 to 3:1 and an intrinsic viscosity of 0.01 to 0.15 dl/g, as an additive to inorganic binders for improving the flowability, and a structural material prepared using binders modified in this manner.

Use of salts of water-soluble

Concentrated aqueous solutions of sulfo-containing melamine-formaldehyde condensates containing hydantoin derivatives to prolong their shelf life. These melamine-formaldehyde condensates are predominantly used as additives in inorganic binders to improve their flow and strength properties.

Long-shelflife concentrated aqueous solutions of melamine-formaldehyde

Additive for inorganic binders, such as cements, calcium sulfate, magnesia cement and the like, which comprises, as the active ingredient, a water-soluble salt of a mixed resin consisting of an aromatic aminosulfonic acid, urea, melamine and formaldehyde, the molar ratio, in the resin, of aromatic aminosulfonic acid to the total amount of melamine and urea being (0.2 to 1.0):1.0 and the molar ratio of melamine to urea being from 0.75:0.25 to 0.30:0.70, and also building materials, having increased flowability and early strength, in which this additive is present.
