摘要:
A coating composition suitable for protecting a substrate from abrasion. The coating composition comprises chlorosulfonated polyolefin, a monomer mixture and catalyst. The monomer mixture is made from (meth)acrylate monomers. The coating composition also acts as a sound deadener, an anti-slip coating, and an anti-wear coating. It can be applied to a variety of substrates especially on a truck bed as a bedliner.

The invention relates to a method for the production of a multilayer structure, comprising the steps 1. applying a functional layer onto an optionally precoated substrate, 2. curing the coating applied in this manner and 3. applying an adhesive onto the cured coating, wherein the functional layer is applied from a water-based coating composition which comprises A) at least one aqueous polymer latex, selected from the group consisting of (meth)acrylate latex, polydiene latex, polydiene copolymer latex, polystyrene latex, nitrile latex and mixtures thereof, and B) at least one amino resin.
摘要:
A process for the production of multi-layer coatings in A' color shades, comprising the successive steps: 1 ) applying a base coat layer in a total process film thickness in the range from 10 to 35 μm to a substrate provided with an EDC primer, 2) applying a clear coat layer onto the base coat layer, 3) jointly curing the base coat and clear coat layers, wherein the base coat layer is applied in a first layer of a modified water-borne base coat modAB prepared by mixing an unmodified water- borne base coat A with an unmodified water-borne base coat B and with a pigment-free admixture component and in a second layer of the unmodified water-borne base coat A.
摘要:
A probe for measuring a property of a liquid under test using interrogating radiation at a predetermined wavelength includes a housing member having a window transparent to interrogating radiation mounted at a first end thereof. A partition transparent to interrogating radiation is mounted in spaced relationship to the window. The partition being and the window cooperate to define an air cavity therebetween. The spacing between the partition and the window is such that radiation reflected from a liquid disposed in contact with the second surface of the partition is prevented from evanescently coupling into the window such that the reflected radiation undergoes total internal reflection in the partition rather than in the window.
摘要:
A process for multilayer repair coating, comprising the following steps: applying a first base coat layer of a conventional, water-borne base coat I containing at least one special effect pigment, applying a second base coat layer of a water-borne base coat II onto the resultant coating, wherein the water-borne base coat II for producing the second base coat layer is feathered out into the zones bordering the repair coating, and wherein this water-borne base coat II comprises A) at least one water-dilutable binder, B) at least one special effect pigment, C) at least one matting agent, D) water and E) optionally, conventional coating additives and/or organic solvents, with the proviso that the water-borne base coat II contains the at least one special effect pigment in a quantity of 25 75 wt.%, relative to the quantity of the at least one special effect pigment contained in water-borne base coat I, applying a clear coat layer of a transparent clear coat onto the resultant coating and curing the coating applied.
