Provided is a prepreg composed of a fibrous substrate impregnated with a reactive or highly reactive polymer composition as a matrix material. The reactive or highly reactive polymer composition contains a (meth)acrylate-based resin comprising at least one of a hydroxyl group, an amine group, a thiol group, an initiator and/or accelerator, and a di- or polyisocyanate which has been internally capped, capped with a capping agent, or a combination thereof. The (meth)acrylate-based resin contains from 20% by weight to 70% by weight of at least one (meth)acrylate monomer and from 1% by weight to 50% by weight of at least one prepolymer.

Composite semifinished products, molded parts produced therefrom, and molded parts produced directly based on hydroxy-functionalized (meth)acrylates, which are cross-linked by means of uretdiones in a thermosetting manner

The present invention relates to an innovative (meth)acrylic reactive resin which cures with low odor or odorlessly. The present invention relates more particularly to reactive resins comprising high-boiling, reactive (meth)acrylic monomers from the group of the polar, cyclically substituted esters of (meth)acrylic acid, more particularly glycerol acetal, ketal or carbonate methacrylates. These new components are used as substitutes for MMA, which represents the major part of the odor nuisance in the existing, prior-art reactive resin systems. Using these new components it is possible to obtain resin formulations which have glass transition temperatures similar to, and properties comparable with, MMA-based resins. The innovative reactive resins are able in addition to exhibit more rapid curing than prior-art MMA-based systems. Reactive resins for the purposes of the invention are reactive monomer mixtures or mixtures of monomers and polymers that when used as a 2-component system can be readily cured.

Low-odour (meth)acrylic reaction resins

A method of producing a trafficway marking, the method including applying a cold plastic to a trafficway surface, to obtain the trafficway marking, where, in less than 5 minutes after the applying, the trafficway marking can withstand the passage of traffic, and where the cold plastic includes from 15% to 45% by weight of a reactive resin; from 1% to 5% by weight of a mixture comprising an initiator; from 7% to 15% by weight of an inorganic pigment; and from 50% to 60% by weight of a mineral filler.

Binding agent for producing road markings ready quickly for traffic

The invention relates to methacrylate resins and to their use.

Methacrylate resins for producing road markings

The present invention comprises a novel formulation for marking travel lanes, such as roads, which following the application can be reopened for traffic after a waiting period that is shortened as compared to the prior art.

An intumescent coating composition and a process for curing the coating to obtain an intumescent coating is provided. The intumescent coating composition contains a thermoplastic polymer which comprises as a copolymerized component, an acid (meth)acrylate or a copolymerizable polyfunctional carboxylic acid; at least one ethylenically unsaturated monomer; an azo or organic peroxide initiator; an acid source; a carbon source; and a gas source.

Intumescent coating composition with enhanced metal adhesion

The invention relates to a coating formulation with improved metal adhesion.

Coating formulation with enhanced metal adhesion

The invention relates to polymer beads having a high content of diacyl peroxides. A prolongation of the pot life in reaction resins based on high-boiling methacrylate esters is achieved due to this high content of peroxides.
