The present invention relates to compositions containing at least one reactive binder, at least one curing agent and/or accelerator, at least one thermally activatable blowing agent and at least one light-weight filler, wherein at least one expanded particle of at least one glass-rich volcanic rock with a closed outer shell is contained as a light-weight filler. The invention also relates to a method for stiffening and/or reinforcing components with thin-walled structures with a corresponding composition as well as to correspondingly produced components.

Composition comprising a light-weight filler

The invention relates to heat-curing reactive compositions based on natural and/or synthetic liquid elastomers containing olefinic double bonds and on vulcanizing agents, where these comprise a quantity, relative to the entire composition, of from 1 to 25% by weight, preferably from 1 to 15% by weight, of at least one liquid polyisoprene, preferably at least one cis-1,4 polyisoprene; a quantity, relative to the entire composition, of from 0.5 to 10% by weight, preferably from 0.5 to 5% by weight, of at least one functionalized liquid polybutadiene; a quantity, relative to the entire composition, of up to 40% by weight, preferably from 1 to 25% by weight, of a triglyceride fraction, the distribution of fatty acid in which comprises a proportion of at least 5% by weight, more particularly at least 60% by weight, of one or more omega-3 fatty acids and/or one or more omega-6 fatty acids; and at least one vulcanizing agent, where the proportion, relative to the entire composition, of synthetic polymers having at least one C&#x2550;C double bond and/or at least one C&#x2261;C triple bond is at least 7.5% by weight, preferably 9% by weight. These have plastisol-like rheology and therefore can be applied at room temperature by conventional spray systems. The invention also relates to use of same as sealant composition or as coating composition, and to methods for bonding components and/or sealing joints between components and/or coating components with use of the compositions.

Heat-curable rubber compositions having plastisol-like rheological properties

The present application provides heat-curing preparations containing (a) a triglyceride fraction, the fatty acid distribution of which has a proportion of at least 5 wt. %, in particular at least 60 wt. %, of one or more &#x3a9;-3 fatty acids and/or one or more &#x3a9;-6 fatty acids, (b) at least one vulcanizing agent selected from the group consisting of (b1) sulfur, (b2) peroxidic vulcanizing agents, (b3) quinones and/or quinone dioximes and/or (b4) dinitrosobenzenes, and (c) at least one inorganic filler.

Heat-curing reactive systems

Sprayable low-viscosity rubber damping compounds based on liquid rubbers or elastomers and vulcanization agents, which contain small quantities of structure-reinforcing fiber fillers, are notable for the absence of previously usual solid rubbers and have a very low viscosity in the application state. Acoustic compounds of this kind are sprayable with the aid of fully automatic application systems, and are preferably processed at the basic body stage in vehicle construction.

Sprayable low-viscosity rubber damping compounds

The cross-linking of cross-linkable compositions containing hydroxyl-bearing and carboxylate-bearing addition polymers of 1,3-butadiene is achieved using catalysts containing alkali metal salts of carboxylic acids.

Catalysts for producing cold or hot cross-linkable masses

Hot-pumpable, heat-curing compositions based on solid ethylene/vinyl acetate copolymers and liquid reactive plasticizers containing olefinically unsaturated double bonds and at least one peroxidic crosslinking agent are suitable as sealing compounds for sealing fine and rough seams in vehicle manufacture. By adding expanding agents, the compositions may be used as lining adhesives. The preferred applications are at the white-shell stage of car manufacture.

Hot-setting wash-fast sealant for shell structures

One-component, heat-curing reactive compositions based on liquid rubbers containing reactive olefinic double bonds and optionally solid rubbers and vulcanization systems based on sulfur have high maxima of the acoustic loss factor over a broad in-use temperature range of around &plus;10&deg; C. to &plus;40&deg; C. in their vulcanized state. These compositions optionally contain fine-particle thermoplastic polymers as an additional component. The compositions are suitable for use as acoustically damping adhesives, sealing compounds or coating compositions.
