The present invention relates to a coating composition, a coating system comprising the coating composition, a coating method and application of the coating system, and a product coated with the coating system. The coating composition comprises: (A) at least one aqueous polyurethane dispersion and/or one aqueous polyacrylate dispersion, wherein the aqueous polyurethane dispersion comprises at least one polyurethane polymer (a), wherein the polyurethane polymer (a) is obtained by a reaction comprising at least one polyurethane prepolymer (a1) and at least one isocyanate-reactive component (a2), wherein the polyurethane prepolymer (a1) is obtained by a reaction comprising the following components: (a1-1) at least one polyisocyanate having an isocyanate functionality of no less than 2, and (a1-2) at least one polyfunctional polyether polyol having a hydroxyl functionality of no less than 3, wherein the polyfunctional polyether polyol has an amount of 1 wt % to 20 wt %, based on the amount of the components for preparing the polyurethane prepolymer being 100 wt %, and (B) at least one crosslinking agent.

Coating composition

A hybrid cord, comprising (a) a core yarn consisting of meta-aromatic polyamide fibers, and (b) at least one wrapping yarn consisting of para-aromatic polyamide fibers that warps around the core yarn at a helical angle, wherein (i) the core yarn makes up 20-60% by weight and the wrapping yarn makes up 40-80% by weight of the hybrid cord, based on the total weight of the hybrid cord, (ii) the twist multiplier of the core yarn is 0-0.5, the twist multiplier of the hybrid cord is 4.5-12; and the twist per meter (tpm) ratio between the at least one wrapping yarn and the hybrid cord ranges from 0.8 to 1.2, and (iii) the helical angle of the wrapping yarn is 10-60 degrees.

Hybrid cords having high tenacity and high elongation at break

A flame retardant additive composition comprising a phosphoric acid salt selected from the group consisting of melamine phosphate, melamine pyrophosphate, melamine orthophosphate, diammonium phosphate, monoammonium phosphate, phosphoric acid amide, melamine polyphosphate, ammonium polyphosphate, polyphosphoric acid amide and combinations of two or more of the foregoing; a metal hydroxide; and an organic phosphate. The flame retardant additive is useful in a wide range of thermoplastic compositions.
