A process for in-mold coating and a mold is disclosed. The process entails (i) obtaining a mold having at least two cavities, (ii) molding a thermoplastic substrate in a first cavity, (iii) introducing the substrate into a second cavity, and (iv) coating said substrate with lacquer, the coating being carried out under enhanced pressure.

Process and mold for molding and coating a substrate

The invention relates to hybrid dispersions comprising nitrocellulose-polyurethanepolyurea particles (NC-PU dispersions) with accelerated drying behavior as compared with the known systems, and also to their use in coating materials.

NC-PU dispersions with accelerated drying

The present invention relates to two-component compositions containing  The present invention also relates to coatings, adhesives or sealants obtained from these compositions.

Two-component polyurethane compositions containing OH-functional polydimethylsiloxanes

Binder combinations containing polyisocyanates, special lactone-based polyols and polyester polyols and to their use for producing coatings, preferably on plastics.

Binder combinations for highly resistant plastic paints

High-solids binder combinations comprising polyisocyanates, special lactone-based polyols and polyacrylate-polyols, a process for preparing such binders, and their use for producing coatings. The lactone-based polyols include &#x3b5;-caprolactone-based polyols having an average hydroxy functionality &#x2267;2 and a number-average molecular weight of from 119 to 2000 g/mol. The polyacrylate resins are prepared by copolymerizing optionally functional polybutadienes, aromatic monomers, hydroxyalkyl esters of acrylic or methacrylic acid having primary hydroxyl groups, aliphatic esters of acrylic or methacrylic acid and Cto Cmonoalcohols, &#x3b1;,&#x3b2;-unsaturated C&#x2013;Cmonocarboxylic or dicarboxylic acids or of one or more monoesters of maleic acid or fumaric acid and Cto Cmonoalchols.

High-solids binder combinations for scratch-resistant topcoats

The present invention relates to a process for producing an aliphatic oligocarbonate diol comprising a) reacting an aliphatic diol with dimethyl carbonate at an elevated pressure in a reaction mixture, and b) subsequently removing unreacted methanol and dimethyl carbonate under a reduced pressure to uncap the terminal OH groups.
