Mold-resistant construction materials distinguished by the presence therein of an azole alone or in combination with a sporulation inhibitor and/or with a substance which is antiadhesive with respect to microorganisms.

Mold-resistant construction materials

Curable compositions comprising a) an alkoxysilane and/or acyloxysilane terminated polymer having at least one end group of the general formula (I) -A-R&#x2014;SiXYZ (I) and b) hollow microspheres made of a copolymer obtained by the polymerization of methacrylonitrile and at least one monomer M2 selected from the group consisting of acrylic acid, methacrylic acid, acrylic acid alkyl esters and methacrylic acid alkyl esters, wherein the copolymer comprises at maximum 5 wt. % units that are due to the installation of additional monomers and is free of units containing chlorine, to a method for the production thereof and to the use thereof as silane cross-linking adhesive, sealing or coating substances.

Curable composition

Silylated polyurethanes can be manufactured by reacting at least one polyol compound, having a molecular weight from 4000 to 20,000 dalton, with a diisocyanate, with a stoichiometric excess of the diisocyanate compound with respect to the polyol compound or compounds, with the result that a polyurethane prepolymer that is isocyanate-terminated is formed; and by subsequently reacting the polyurethane prepolymer with one or more OH-terminated silanes of formula (1) to yield a polyurethane having predominantly terminal alkoxysilyl groups. In formula (1), m is equal to 0, 1, or 2, Ris an alkyl residue having 1 to 4 carbon atoms, Ris an alkyl residue having 1 to 4 carbon atoms, Ris a divalent organic residue having 1 to 12 atoms, selected from C, N, S, and/or O, in the chain, but by preference exclusively carbon atoms, Ris a hydrogen atom or an alkyl residue having 1 to 10 carbon atoms, and R is a difunctional organic group, preferably a linear or branched alkyl group having 1 to 6 carbon atoms. The silylated polyurethanes are suitable for use in a preparation as an adhesive, sealant, or coating agent.

Curable compositions containing silylated polyurethanes

The invention relates to curable compositions comprising a) at least one organic polymer selected from polyethers and polyacrylic acid esters, wherein the organic polymer has at least one defined, cross-linkable end group having at least one C-C-alkoxy- or C-C-acyloxy radical, b) at least one poly(dialkylsiloxane) having at least one defined, cross-linkable end group having at least one vinyl radical and likewise at least one C-C-alkoxy- or C-C-acyloxy radical and c) at least one flame-retarding additive selected from red phosphorus, organic phosphor compounds, ammonia polyphosphate, metal hydroxides, expandable graphite, zinc borate and melamine salts, to the use of such compositions as adhesive, sealing or coating material, in particular for providing a substrate having a flame-retardant, elastic coating, to a coating thus obtained and to the use of at least one poly(dialkylsiloxane) b) to improve the fire properties of a curable composition comprising at least one organic polymer a).

Curable compositions having improved fire properties

A method for producing a silylated polyurethane including the steps: (A) converting (i) at least polyol compound having a molecular weight of 4,000-30,000 g/mol and at least one monofunctional compound relative to isocyanates and (ii) at least one diisocyanate at a stoichiometric excess of the sum of the polyol compound(s) and monofunctional compound relative to the diisocyanate compound(s), whereby a hydroxyl-terminated polyurethane prepolymer is formed; and (B) converting the polyurethane prepolymer and one or more isocyanate silane(s) of the formula (I): OCN&#x2014;R&#x2014;Si&#x2014;(R1)(-OR2), where m is 0, 1 or 2, each R2 is an alkyl radical having 1 to 4 carbon atoms, each R1 is an alkyl radical having 1 to 4 carbon atoms, and R is a difunctional organic group. Also compounds comprising the silylated polyurethane that can be so produced, and the use thereof as an adhesive and sealant or coating composition.

Curable compound comprising silylated polyurethane

This disclosure relates to a curable composition comprising at least one polymer A with at least one reactive silyl group and at least one polymer B with at least one reactive silyl group, the number of reactive silyl groups in the polymer A being greater or equal to the number of silyl groups in polymer B and the reactive silyl groups being capable of cross-linking to form siloxane bonds. The disclosure also relates to preparations containing a composition of this type and to the use of said compositions.

Compositions consisting of partially silyl-terminated polymers

Non-ionic surfactants are used to reduce the adhesion of microorganisms to surfaces of materials by coating such surfaces with the surfactants or incorporating the surfactants into the materials.

Adhesion inhibition of microorganisms by non-ionic surfactants

This invention relates to the use of eugenol and/or eugenol derivatives for inhibiting the asexual propagation of fungi. This invention also relates to filter media, adhesives, building materials, building auxiliaries, textiles, pelts, paper, skins or leather, laundry detergents, cleaning compositions, rinse agents, hand washing preparations, manual dishwashing detergents, machine dishwashing detergents and preparations for finishing building materials, building auxiliaries, textiles, pelts, paper, skins or leather that contain eugenol and/or eugenol derivatives and to preparations for treating building materials, building auxiliaries, textiles, pelts, paper, skins or leather that contain eugenol and/or eugenol derivatives.
