Process for coating, adhesive bonding and binding of mineral surfaces

A process for coating of at least one surface, or for adhesive bonding or for binding of surfaces of at least one mineral material with a 2-component plastic resin, the process comprising:

• applying the 2-component plastic resin to the at least one surface or binding the surfaces of the at least one mineral material with the plastic resin;
• and
• allowing the plastic resin to cure,
• wherein the 2-component plastic resin comprises from 0.01 to 10% by weight of at least one hydroxy- or alkoxyaminosilane compound of formula (I)
• wherein:
• X independently of one another, are OH, CH3, O[CH2]PCH3;
• Y is [CH2]t, [CH2]rNH[CH2]s;
• R and R′ are H, [CH2]tCH3;
• t is 0-10;
• n is 1-3;
• p is 0-5;
• m is 4-n;
• and
• r and s independently of one another, are 1-10,
• wherein the 2-component plastic resin is a hydrophobic polyurethane resin which is obtained by mixing a polyisocyanate component (i) with a polyol component (ii), wherein the polyol component (ii) comprises one or more polyols which are known from fat chemistry and obtained from at least one selected from the group consisting of an animal fat, an animal oil, a vegetable oil, and a vegetable fat, and the alkoxyaminosilane compound is comprised in the polyol component (ii).
