Abstract:
A process for coating, for adhesive bonding or for binding of surfaces of mineral materials with a 2-component plastic resin, selected from a hydrophobic polyurethane resin and a hydrophobic epoxy resin, by applying the plastic resin to the surface or binding the surfaces of the mineral materials with the plastic resin and allowing the plastic resin to cure, wherein the plastic resin comprises from 0.01 to 10% by weight of one or more hydroxy- or alkoxyaminosilane compounds of the general formula (I) in which: X independently of one another, are OH, CH3, O[CH2]pCH3; Y is [CH2]t, [CH2]rNH[CH2]s; R, R′ are H, [CH2]tCH3; t is 0-10; n is 1-3; p is 0-5; m is 4-n; r, s independently of one another, are 1-10.
Abstract:
A proppant comprises a particle and a polycarbodiimide coating disposed on the particle. The polycarbodiimide coating comprises the reaction product of a polymeric isocyanate and a monomeric isocyanate, in the presence of a catalyst. A method of forming the proppant comprises the steps of providing the particle, providing the polymeric isocyanate, providing the monomeric isocyanate, providing the catalyst, reacting the polymeric isocyanate and the monomeric isocyanate in the presence of the catalyst to form the polycarbodiimide coating, and coating the particle with the polycarbodiimide coating.

Abstract:
The present invention relates to a process for the production of roads, tracks, and other areas used by traffic, by producing a mixture comprising ground road surfacing, mineral material, and/or glass, a polymer reaction mixture and, if desired, further additions, and applying it to a substrate material, and hardening it. The present invention further relates to roads, tracks, and other areas used by traffic, obtainable by a process of this type.
