The present invention relates to a resin composition, comprising (a) an epoxy resin; (b) a curing agent comprising the structure of formula C1; (c) an inorganic filler; wherein Ris (a) a siloxane group of formula C1a or (b) or both a siloxane group of formula C1a and an ester group of formula C1b; Ris selected from a bulky Cto Calkyl group comprising at least one tertiary or quaternary carbon atom; R, R, Rare independently selected from methyl, ethyl and 1-propyl; Ris selected from a linear or branched Cto Calkyl; Xis selected from a divalent Cto Calkanediyl group; and n is an average number of repeating units and is from 1.05 to 200.

Epoxy resin composition

Process for the removal of volatile compounds from a tackifier comprising a resin with repeating units of formula I wherein Ris a linear or branched alkylen group with 1 to 10 carbon atoms and Ris a linear or branched, saturated or unsaturated N aliphatic hydrocarbon group with up to 20 carbon atoms, and optionally a plasticizer, wherein the tackifier is passed through at least one evaporator as film and the volatile compounds are removed from the film. 

Process for removal of volatile compounds from tackifiers

A curable composition comprises a) at least one epoxide compound E having at least two epoxide groups; b) at least one amine A having at least two amine hydrogens; and c) at least one acrylic ester U; wherein the epoxide compound E comprises at least one epoxide compound E', the amine A comprises at least one amine A&#x2032;, and the acrylic ester U comprises at least one acrylic ester U&#x2032; whose Hansen solubility parameters for the dipole forces &#x3b4;and for the specific interactions &#x3b4;satisfy the following conditions: A suitable choice of the Hansen solubility parameters of the constituents ensures that the acrylic ester is incorporated covalently into the curing material, preventing subsequent evaporation of the diluent.

Curing of epoxy resin compositions comprising cyclic carbonates using mixtures of amino hardeners and catalysts

The present invention relates to the use of cyclic carbonates of the formula I or a mixture thereof in epoxy resin compositions and also to epoxy resin compositions which comprise such cyclic carbonates. 

Use of cyclic carbonates in epoxy resin compositions

A process for curing an epoxy resin composition containing an epoxy resin and a compound of the general formula I: where Rand Rindependently are hydrogen, C-C-alkyl, C-C-alkoxy-C-C-alkyl, C-C-cycloalkyl, phenyl, phenyl-C-C-alkyl, C-C-alkenyl or C-C-alkynyl, or Rand Rtogether are a C-C-alkylene group; and where Rand Rindependently are hydrogen, C-C-alkyl, C-C-alkoxy-C-C-alkyl, C-C-cycloalkyl, phenyl, phenyl-C-C-alkyl, C-C-alkenyl or C-C-alkynyl, or Rand Rtogether are a C-C-alkylene group. The process includes adding amino hardeners, where 0.1% to 50% by weight of the amino hardeners are aliphatic, cycloaliphatic or aromatic amine compounds having 1 to 4 primary amino groups and optionally further functional groups, selected from secondary amino groups, tertiary amino groups, and hydroxyl groups. In the case of the cycloaliphatic and aromatic amine compounds, the primary amino groups are attached as aminomethylene groups (HN&#x2014;CH&#x2014;) to the cycloaliphatic or aromatic ring system (referred to below for short as co-hardeners).
