Epoxy resin composition

The disclosure relates to a curable mixture for use in impregnation of paper bushings comprising a resin mixture of a bisphenol-A-diglycidylether (BADGE) and a bisphenol-F-diglycidylether (BFDGE), methyltetrahydrophthalic anhydride (MTHPA) as hardener, and an accelerator selected from the group consisting of tertiary alkylamine aminoethylalcohols and corresponding ethers thereof as well as paper bushings impregnated with such mixture and uses of such mixture.

Compositions for use in impregnation of paper bushings

A multiple component anhydride-free, thermosetting epoxy resin composition comprising, (A) at least one epoxy resin, and (B) at least one curing agent selected from the group of (b1) a polyetheramine of the formula (1) (Formula (1)), wherein x is a number of from 2 to 8, and (b2) a polyetheramine with at least one terminal end group of the formula (2) (Formula (2)), and (C) at least one epoxy silane, is, in particular, suitable for the manufacture of instrument transformers and dry-type transformers by casting, potting and encapsulation processes, wherein said articles exhibit good mechanical, electrical and dielectrical properties. 

Thermosetting epoxy resin composition for the preparation of articles for electrical engineering, and the articles obtained therefrom

A curable composition comprising a mixture of homopolymers of an aliphatic polyisocyanate and a cycloaliphatic polyisocyanate, a polyester polyol or polyether polyol and a filler. The composition is particularly suitable for use in the manufacture of outdoor insulation system articles.

Curable polyurethane composition for the preparation of outdoor articles, and the articles obtained therefrom

The invention relates to a curing agent for thermosetting epoxy resins comprising (a) at least one aromatic amine containing at least two amino groups, and (b) at least one clathrate compound obtained by reacting a tetrakisphenol of the formula (1), or a 9,9-Bis(4-hydroxyphenyl)fluorene of formula (2), as the host molecule, and an imidazole or an imidazolium derivative as the guest molecule, wherein the substituents are as defined in the description, and n is the number 0, 1, 2 or 3, which can advantageously be used for the curing of epoxy resins. In addition, the invention also relates to a process for the preparation of a cured article, a process for the preparation of insulation systems for electrical engineering and a cured article obtained by the processes.

Impregnation of air core reactors

Disclosed is a curable composition comprising an epoxy resin and a filler composition, a cured product obtained by curing said curable composition as well as the use of the cured products as electrically insulating construction material for electrical or electronic components.

Direct overmolding

A curable epoxy resin composition of an epoxy resin (a) and a combination (b) of an antioxidant (b1) and a UV absorber (b2). The UV absorber (b2) is a benzotriazole. The antioxidant (b1) is a compound of general formula I: wherein: R=&#x2014;H, &#x2014;OH, &#x2014;O&#x2014;Calkyl, &#x2014;Calkyl, &#x2014;Ccycloalkyl being unsubstituted or being substituted with Calkyl or Calkoxy, or &#x2014;CH&#x2014;Ccycloalkyl being unsubstituted or being substituted with Calkyl or Calkoxy; R=independent from each other &#x2014;Calkyl; and R6=a bivalent aliphatic, cycloaliphatic or aromatic residue. The weight ratio of (a) to (b) is from 90.0:10.0 to 98.5:1.5, with the proviso that the weight portion of (b1) is at least 0.5. The cured product has very good weather resistance after curing by polyaddition with a polycarboxylic acid anhydride or by homopolymerization. The cured product is suitable as an electrical insulation material.
