The presently claimed invention relates to a process for preparing urea urethane polymer, liquid compositions comprising the urea urethane polymer and the use of the urea urethane polymer as a thickening and thixotropic agent for water based and solvent based paint and coating formulations, lacquer, varnish, paper coating, wood coating, adhesive, ink, cosmetic formulation, detergent formulation, textile and drilling muds plaster formulations, PVC plastisol and cement formulations.

Process for preparing urea urethane polymer

The present invention relates to the use of an ultraviolet radiation absorbing polymer composition (UVRAP) as an UV absorbing agent in a coating for non-living and non-keratinous materials and a composition stabilized against light-induced degradation comprising a coating for non-living and non-keratinous materials subject to light-induced degradation, and the ultraviolet radiation absorbing polymer composition (UVRAP).

Use of an ultraviolet radiation absorbing polymer composition (UVRAP) as an UV absorbing agent in a coating for non-living and non-keratinous materials

The invention relates to a process for preparing oligo- or polyalkylene ether-modified polysiloxanes by transesterification of alkoxy-functionalized polysiloxanes with OH&#x2014; terminated oligo- or polyalkylene ethers in the presence of the tetra-n-C-C-alkoxy-titanate as catalyst. Oligo- or polyalkylene ether-modified polydimethylsiloxanes obtainable through this process are suitable as defoamers, as wetting agents, and as additives in coating material formulations.

The invention relates to a process for preparing oligo- or polyalkylene ether-modified polysiloxanes by transesterification of alkoxy-functionalized polysiloxanes with OH-terminated oligo- or polyalkylene ethers in the presence of an alkanesulfonic acid as catalyst. Oligo- or polyalkylene ether-modified polydimethylsiloxanes obtainable through this process are suitable as defoamers, as wetting agents, and as additives in coating material formulations.

The present invention relates the use of a 2-(2-hydroxyphenyl)benzotriazole compound of the formula R(QUV)as an UV absorbing agent in coatings.

The present invention relates to symmetric diesters of hydroxyalkyl-4-hydroxy-tetraalkylpiperidine compounds and their use as light stabilizers. They are compatible with and soluble in coating formulations of different polarity.

Light stabilizers

The present invention relates to a homogenous liquid blend comprising a photoinitiator and an alkoxylate surfactant for incorporation into aqueous based and solvent based radiation curable systems. In particular the invention relates to a homogenous liquid blend which is liquid at room temperature comprising at least 30% by weight with regard to the whole blend of a solid photoinitiator of the radical type and 1-70% by weight of at least one alkoxylated liquid surface active agent and optionally an organic diluent.

Liquid photoinitiator blend

The instant invention pertains to a concentrated aqueous dispersion of organic light stabilizers with a particle size of less than 1000 nm, prepared by heterophase radical polymerization of ethylenically unsaturated monomers in the presence of the light stabilizers, wherein the weight ratio of light stabilizer to polymeric carrier is greater than 50/100. Another aspect of the invention is a process for the preparation of such aqueous dispersions with high light stabilizer content. Aqueous dispersions prepared according to this process are useful ingredients for adhesives, aqueous emulsions of natural or synthetic rubbers, water based inks or a water based coating compositions, which are consequently also subjects of the invention.
