The zinc rich coating is divided into two major categories of organic and inorganic.
Commonly used organic epoxy, chlorinated rubber, vinyl resin and polyurethane resin as binder, the most commonly used epoxy zinc rich coating, in which the polyamide curing zinc rich epoxy primer is organic zinc-rich primer application the largest species. Zinc is the aggregate into the paint as the expense of polar pigments and fillers and resin, fillers, solvents, and to protect the metal substrate surface, but lack the heavy anti-corrosion features to give the metal substrate surface. Therefore, based on theRead More …
Application notes for fissure powder coatings
Electrostatic spraying with ordinary powder spraying techniques, no special requirements. Application is quick and easy, not the problem of coating, a spray can, without increasing the coating process. Can automatically spray gun, the more uniform texture. Gully and concave need to manually fill spray. Powder coating powder construction process should seek to spray to the metal workpiece surface is uniform coating of uniform thickness and suitable. Coating have the following characteristics: Thick coating can be larger uniform fissure effect, clear texture; thinRead More …
Primers based on spherical zinc dust and Micaceous iron oxide
Primers based on spherical zinc dust and Micaceous iron oxide(MIO) The preparation of zinc rich primers was based on a semisolid epoxy resin, a polyaminoamide adduct-like hardener, spherical zinc dust and the MIO. Paints were formulated with a pigment volume concentration (PVC) from 40 to 65%; the volume ratio of zinc dust and MIO was 1:1. The partial replacement of spherical zinc dust by MIO was examined with PVC = 65%; the ratio between spherical zinc dust and MIO wasRead More …
Nanotechnology is rapidly gaining recognition to significantly benefit for the coatings industry
Nanotechnology is rapidly gaining recognition as having the potential to provide significant benefits for the coatings industry. The most publicized benefits include scratch resistance, UV protection and weathering protection. In addition to improved coating performance, nanotechnology also provides benefits, such as reduced energy and reduced material consumption. Nanoparticles including metal oxides, clays and resins dominate the market for nanotechnology-based coatings. Newer carbon based nanotubes are now being developed for use in transparent conductive coatings and low weight, high strength coatings.Read More …
Zinc rich primer-two pack system enriched with metallic zinc to provide outstanding performance
Zinc rich primer is a two pack system enriched with metallic zinc to provide outstanding performance in highly corrosive environment. Metallic Zinc imparts Cathodic protection to the base metal and Epoxide groups react with polyamide / Amine adduct hardener to form tough, non convertible film at ambient temp.It resists photo degradation by UV light as it contains UV absorber. RANGE OF APPLICATION Suitable for application as a priming coat on structural steel, pipelines, tank exteriors of refineries, power generation plants,Read More …
Zinc Rich Primer is an organic zinc rich primer for steel and ferrous metals
Zinc Rich Primer is an organic zinc rich primer for steel and ferrous metals that combines the resistance properties of epoxy and the galvanic protection of zinc.This is a pure zinc epoxy base one-package primer. This high performance epoxy compound fuses zinc to the metal substrate and protects against corrosion equal to Hot Dip Galvanizing (meets and exceeds ASTM A780 specification for touch-up and repair of Hot Dip Galvanize). Clearco Zinc Rich Primer is self-healing, and prevents creepage even whenRead More …
Creating a new coating quality national standard is necessary
Help to improve the overall level of China’s coating industry As we all know, there are still a certain gap between the overall level of the coating industry in China compared with developed countries, resulting in this phenomenon are many reasons. But the most fundamental reason is the different coating standard. Formulation and implementation of advanced scientific national industry standards and must be able to produce high-quality coating products, not vice versa. Our coating products out the door selling overseasRead More …
Coating appearance quality inspection methods and problems
The appearance of the coating quality requirements include: the color of the coating, the flatness of the film, the impurity content of the coating gloss and coating 1.Coating color test The color is light on the object surface colored light absorption and reflection, feeling again the role of the visual organ formation. The coating of the color test is divided into visual comparison method and instrument measurements. The visual comparison method, you must first preparation of standard colors and darker,Read More …
Coatings Technology Knowledge:the characteristics of the powder coating
The powder coating is a new type of solvent-free 100% solid powder coating. It has two categories: the thermoplastic powder coating and thermosetting powder coating. Coating made of special resin, fillers, curing agents and other additives, to a certain proportion of mixed and then by hot extrusion and crushing process of sifting and other prepared from. At room temperature, storage stability, electrostatic spray or fluidized bed dipping, and then the baking heat of melting and solidification, so that the formationRead More …
