The present invention refers to polyurethane adhesives with semi-crystalline and highly crystalline polyesters, a method for the production of the same as well as the use of the polyurethane adhesive in the production of electronic devices.

Polyurethane adhesive with semi-crystalline and highly crystalline polyesters

The present invention relates to a moisture curable hotmelt adhesive composition comprising at least one polyurethane prepolymer obtained from the reaction of a) at least one polyether; b) at least one (meth)acrylic resin; c) at least one crystalline polyester; d) at least one amorphous polyester; e) at least one isocyanate compound; in a presence of a catalyst, wherein at least one of said polyether, crystalline polyester and amorphous polyester is partially or completely bio-based material.

Bio-based reactive polyurethane hotmelt adhesives

The invention relates to a method for producing a cured composition which has at least one oxazolidinone ring and at least one isocyanurate ring and is cross-linked by the same, starting from a liquid reactive mixture which, based on the total weight thereof, contains at least one epoxy resin, at least one polyisocyanate, at least one polyol, and at least one catalyst composition. The invention further relates to the cured composition obtainable thereby.

Cured composition having high impact strength and temperature resistance, based on an epoxy resin and a polyisocyanate

The present invention relates to a catalyst composition for curing resins containing epoxy groups, in particular epoxy/polyurethane hybrid resins, the catalyst composition containing an imidazolium salt, in addition to a base, as well as a method for curing such resins in the presence of the catalyst composition, to the use of the catalyst composition for curing resins containing epoxy groups, to resin systems comprising a resin containing epoxy groups and the catalyst composition, and to a dosing system that comprises the resin and the catalyst composition.

Catalyst composition for curing resins containing epoxy groups

The present invention relates to a method for producing a cured composition, which has at least one oxazolidinone ring and at least one isocyanurate ring and is crosslinked thereby, starting from a liquid reaction mixture comprising: (a) at least one liquid, aromatic epoxy resin; (b) at least one liquid, aromatic polyisocyanate; and (c) a catalyst composition; relative to the at least one polyisocyanate, the at least one epoxy resin is used in amounts such that the molar equivalent ratio of epoxide groups to isocyanate groups is at least 0.4; and curing the reaction mixture to give a cured polymer composition comprising at least one oxazolidinone ring and at least one isocyanurate ring, and also to the cured compositions obtainable by these methods.

Oxazolidinone- and isocyanurate-crosslinked matrix for fiber-reinforced material

The present invention relates to adhesive compositions containing a prepolymer which can be obtained by reacting a reaction mixture containing: at least one epoxy resin; at least one polyetherdiamine or polyethertriamine; at least one carboxyl-terminated butadiene-acrylonitrile copolymer (CTBN); and rubber particles having a core/shell structure. The invention also relates to methods for curing said compositions, to the cured adhesive compositions thus obtained, to the use thereof for bonding components and to the components thus obtained.

Epoxy resin composition

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.
