Coating composition system, the preparation method, and the use thereof

A method for forming a stain resistant and soft tactile texture coating onto a substrate, comprising the steps of:

• forming a primer coating onto the substrate with a first composition comprising:
• a hydroxyl resin selected from one or more of the group consisting of alkyd resins, acrylic resins, polyester resins, polyurethane resins, epoxy resins, and modified silicone resins;
• a hardener resin having functional groups which react with hydroxyl groups of the hydroxyl resin;
• wherein the molar ratio of the hydroxyl groups of the hydroxyl resin is controlled to be excessive over the molar ratio of the functional groups of the hardener resin;
• forming a top coating onto the primer coating with a second composition comprising:
• an alkenyl containing polysiloxane of formula (I)
• wherein
• R represents an alkyl group having 1 to 8 carbon atoms, or an alkenyl group having 2 to 10 carbon atoms;
• R1 and R3 each independently represents an alkyl group having 1 to 8 carbon atoms;
• R2 represents an alkenyl group having 2 to 10 carbon atoms;
• l+m+n+a is within the range from 200 to 15000;
• wherein the alkenyl content of the alkenyl-containing polysiloxane is not less than 0.2 mmol/g and not greater than 5.0 mmol/g;
• a Si—H bond containing polysiloxane of the formula (II)
• wherein
• R4 and R5 each independently represents an alkyl group having 1 to 8 carbon atoms;
• R6 represents an alkyl group having 1 to 8 carbon atoms, or H;
• o+p+q+b is within the range from 5 to 500;
• a catalyst selected from one or more of the group consisting of platinum compounds, palladium compounds, rhodium compounds and ruthenium compounds.
