Abstract: Described is a method for producing a coating with an aqueous coating composition AC, the method including: a) applying the aqueous coating composition AC to a cementitious substrate; and b) curing the applied aqueous coating composition AC. The aqueous coating composition AC includes at least one amino-functional copolymer VC and at least one epoxy silane ES and the coating composition has a pH in a range of 3 to 6.5. The weight ratio between amino-functional copolymer VC and epoxy silane ES (VC/ES) is in a range from 1.0 to 9.5. The composition can display self-etching properties on concrete surfaces, and thus, cementitious substrates do not have to be mechanically or chemically pretreated before the composition is applied.

Abstract: An adjustable cargo gate system for a flat bed of a truck or trailer comprising a grate of adjustable length having a center section and end sections which telescope into or out of the center section, and vertical and horizontal braces to hold the gate upright attached to cars that engage with and slide on tracks attached to the truck bed, is modified with the improvements hereinafter described. Track extensions onto the tailgate of the truck allow the gate system to be disposed at the rearmost end of the tailgate when opened flat. One-piece car brace members in the shape of right triangles replace the separate vertical and horizontal brace members and the separate sliding car members of the original system. Curved end sections are provided to enclose the sides of the opened tailgate. A bed-liner with integral tracks make installation of the system much simpler.
