Abstract: The invention provides a composition for fixing wound items comprising at least one ?,?-unsaturated polyester, and at least two different monomeric or oligomeric ethylenically unsaturated components. The composition of the present invention provides a composition having low curing emissions, low viscosities and excellent impregnation properties. After curing, these impregnation materials show high mechanical toughness levels even at elevated temperatures.

Abstract: A composition for fixing wound items having excellent thermal transfer properties and a high level of electrical insulating properties under humid conditions comprising: A) 5 to 80 wt % of at least one polyolefin-containing unsaturated polyester resin, B) 0 to 60 wt % of at least one unsaturated polyester resin different from A), C) 5 to 70 wt % of at least one reactive diluent, D) 0.01 to 15 wt % of customary additives, and E) 0.1 to 20 wt % of at least one free radical initiator, the wt % being based on the total weight of the composition.

Abstract: A composition for fixing wound items comprising A) 0 to 90 wt % of at least one ?, ?-unsaturated polyester and/or polyester imide resin based on at least one unsaturated mono-, di- or tricarboxylic acids and/or mono-, di- or tricarboxylic acid group containing molecules, at least one polyol and/or, in case of an unsaturated polyester imide, at least one imide having 5-membered cyclic imide moieties, B) 0.1 to 80 wt % of at least one inorganic and/or organic-inorganic hybrid component having functionalities to react with component A) and C), C) 2 to 80 wt % of at least one monomeric and/or oligomeric unsaturated component to react with component A) and B), and D) 0 to 15 wt % of customary additives, the wt % being based on the total weight of the composition. The composition provides excellent thermal transfer properties and a high level of electrical insulation properties with excellent adhesion and thermal stability.
