The invention relates to a method for welding a polyamide plastic and a poly(meth)acrylate&#x2014;particularly a polymethyl methacrylate&#x2014;plastic using a primer, said primer containing at least one copolymer synthesised from at least one styrene or styrene derivative and at least one maleic anhydride or maleic anhydride derivative. The invention also relates to correspondingly welded products.

Method for welding polyamide and poly(meth)acrylate plastics

The present invention relates to a method for welding two polyamide plastics using a primer, the primer containing at least one polymer synthesized from at least one maleic anhydride or maleic anhydride derivative. The invention also relates to correspondingly welded products.

Method for welding two polyamide plastics

Disclosed is a method for welding a polyolefin plastic and a plastic based on at least one polymer containing carbonyl groups, using a primer which contains, in relation to the proportion of polymer, at least 20 wt. % of a polymer that comprises maleic anhydride or maleic anhydride derivative units. Also disclosed are correspondingly welded products.

Method for welding a polyolefin plastic and a plastic based on a polymer containing carbonyl groups

The present invention relates to a catalyst composition for curing epoxy group containing compounds comprising a base and a quaternary ammonium salt, of Formula (I): with R, R, R, R, R, Y, A and X being as defined herein. Also encompassed are adhesive compositions containing said catalyst composition and the use of the catalyst composition.

Storage stable heat activated quaternary ammonium catalysts for epoxy cure

The present invention relates to heat-curable compositions containing a mixture of reactive epoxy resins that contains, based on the mass of all epoxy resins, a) at least 10 wt % of an epoxy group-containing reaction product of epichlorohydrin with polypropylene glycol which has an epoxy equivalent weight of at least 250 g/eq, and b) at least 10 wt % of an epoxy group-containing reaction product of epichlorohydrin with a novolac resin which has an epoxy equivalent weight of at least 175 g/eq, and at least one latent hardener.

One component epoxy resin composition

The subject matter of the present Application is two-component compositions whose first component is a mixture of reactive epoxy resins and optionally further formulation constituents which contains, based on the mass of all epoxy resins,

Epoxy resin composition with reduced toxicity

The present application is directed to use of a thioether compound, obtainable from a first educt that comprises at least two thiol groups and from a second educt that comprises at least one &#x3b1;,&#x3b2;-unsaturated amide group as well as at least one tertiary amine group, for the hardening of reactive resins.

Hardener for epoxy resins

A resin component for a one- or two-component adhesive, a matrix resin, or a structural foam, comprising: C1) at least one epoxy resin, having an average of more than one epoxy group per molecule, that does not correspond to the definition of component C2); C2) at least one oligomeric or polymeric urethane-group-free polyether compound. A one- or two-component epoxy adhesive, structural foam, or matrix material for composites, comprising the aforesaid resin components.
