Abstract
A moisture-curing two-component composition consisting of a component A containing at least one polyoxyalkylene, polyolefin and/or polyacrylate prepolymer having at least one hydrolysable silane group and at least one solid inert additive selected from hydrocarbons, polyesters or polyamides, a component B containing at least one crosslinking compound for the prepolymers, and auxiliary substances and additives in one or both components, the component A and the two-component composition each having hot-melt adhesive properties.
Claims13
A moisture-curing two-component composition consisting of:
- a component A containing at least one polyoxyalkylene, polyolefin and/or polyacrylate prepolymer having at least one hydrolysable silane group and 0.1 to 20 wt % relative to the weight of the composition of at least one solid inert additive comprising polyamide and optionally another compound selected from the group consisting of hydrocarbons, polyesters or both;
- and
- a component B containing at least one crosslinking compound for the prepolymer, component B having a viscosity of 5,000 to 800,000 mPas at 25° C.;
- and
- optionally auxiliary substances selected from the group consisting of resin, plasticizer, stabilizer, water-dissolving or water-absorbing substance, pigment, filler, thickening agent and combinations thereof;
- the two-component composition and component A each having hot-melt adhesive properties wherein the composition is free of metal catalyst and comprises a catalyst consisting of amine compounds and/or silane adhesion promoters with amino groups.
