A defoamer composition contains a compound based on polybutadiene having at least one repeat unit selected from the divalent radicals:

Defoamer composition based on organofunctionally modified polybutadienes

A defoamer composition based on organofunctionally modified polysiloxanes contains one or more laterally polyether-modified polysiloxanes as component A and at least one terminally polyether-modified polysiloxane as component B.

Defoamer composition based on organofunctionally modified polysiloxanes

The present invention relates to a formulation comprising a polyether siloxane, which is characterized in that a polyether that is terminated with an ester group and that is different from the polyether siloxane is present in the formulation in an amount of from 0.5 to 10% by weight based on the complete formulation, to a process for the production of a defoamed composition, wherein the inventive formulation is added to the composition to be defoamed, and to a composition comprising a formulation according to the invention, wherein the composition is a coating agent, a paint or a varnish.

Formulation and its use as defoamer

The present invention relates to a process for producing hydrosilylatable, eugenol-based polyethers, to the conversion thereof into polyether siloxanes and also to the products that may be produced by this process and to the use of said products as surfactants.

Acrylate-terminated urethane polybutadienes from low-monomer 1:1 monoadducts from reactive olefinic compounds and diisocyanates and hydroxy-terminated polybutadienes for liquid optically clear adhesives (LOCAs)

Process for the preparation of eugenol polyethers that can be hydrosilylated and eugenol polyethersiloxanes and use thereof

A dispersing resin of formula (I), T-P-Z-T (I). The dispersin resin of this formula is defined where T is at least one monocarboxylic acid, where Z includes at least one of a polyallylamine and a poly(C2-4-alkyleneimine), and where P is a polyester obtained by a process of reacting a dicarboxylic or a polycarboxylic acid and a diol or a polyol.

Dispersing resins

The present invention relates to compositions comprising eugenol polyethers and/or eugenol polyethers modified with siloxanes, and to the use of eugenol polyethers in polyether siloxanes based on these eugenol polyethers as wetting agents.

Use of eugenol polyethers and eugenol polyether siloxanes as wetting agents
