Epoxy resin coatings crosslinking agent
Epoxy resin coatings crosslinking agent,Chose several kinds of epoxy crosslinking agent, the mixture of epoxy resin coating, compares the physical properties of the epoxy coating and anticorrosion performance, examines the epoxy coating crosslinked under different temperature conditions, discusses the influence of crosslinking agent on the properties of low temperature construction.
Epoxy resin coatings have excellent anti-corrosion performance and chemical resistance, good paint film mechanical properties, on various substrate with excellent adhesion, with a variety of coating performance is good, but with fluorocarbon polymer coating, polyurethane coating, acrylic coating of high performance coatings such as supporting system, constitute a long-acting type anticorrosive coating.
As a long-term corrosion protection coatings, has been widely used in ships, Marine engineering and other fields. Epoxy resin containing two lively epoxy groups and hydroxyl groups, with multiple amine, polyamide resin, phenolic resin, amino resin and isocyanate resin and so on, made from a variety of coatings.
Epoxy coatings according to the crosslinking temperature can be divided into four categories, the crosslinking agent is low temperature crosslinking agent, crosslinking agent at room temperature, high temperature medium temperature cross-linking agent and crosslinking agent.
At present, the domestic epoxy anticorrosive coating of normal temperature crosslinked coating with polyamide kind of crosslinking agent. Epoxy/polyamide crosslinking system has a lot of application in ships, Bridges, oil pipelines, and other areas of the heavy-duty.
But, like the traditional amide, polyamide class crosslinking agent in construction of the low temperature by a certain limit, when the temperature is below 10 ℃, the polyamide crosslinking agent with low molecular weight epoxy resin reaction becomes very slowly, while using dimethyl methyl phenol ammonia as crosslinking accelerator, it is possible that under low temperature (7 ~ 10 ℃) crosslinking rate, however, still cannot meet the requirements of winter construction.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material :
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Therefore, can be used under the condition of low temperature of epoxy resin coating, to meet the steel structure building, port machinery, Bridges, ships and other large steel structure the demand of the winter construction, is imperative.
Poly (aspartic acid ester polyurea coatings broke through the bottleneck of short-term construction activation, the activation period can reach 2-3 h, can be like ordinary coatings, easily applied to many fields of coating, including heavy-duty coating;
Poly (aspartic acid ester type polyurea coatings as weather resistance protective paint, and the traditional epoxy zinc rich primer (inorganic zinc rich primer), micaceous iron oxide intermediate paint combination, can make the green environmental protection, life in more than 30 years of long-lasting heavy anti-corrosion coatings. Very suitable for the steel structure, bridge, Marine engineering, offshore drilling platform of anti-corrosion coating, and for Marine coatings, such as wind power blade coating.
With the new structure of poly (aspartic acid ester as main resin developed polyurea anti-corrosion coatings, has a long ultraviolet resistance performance, excellent wear resistance, high solid low viscosity, long construction period, etc. Combined with traditional anticorrosion primer/intermediate paint, to do environmental protection long-life heavy-duty coating.
A kaleidoscope of colors in nature, but the most basic is red, yellow, blue, and three, often referred to as trichromatic color. In the three primary colors according to the different proportion mixing mixture of another color, complex color. For example, red + yellow = orange; Blue + yellow = green; Called orange and green color. Three primary colors of the complex color, its corresponding in the color ring another color for compensation. For example, green, yellow and blue Mosaic of red is the color of green.
In color, add white color or multicolor dilute, "saturation" are available on different color, adding different amount of black, "lightness" different kinds of color can be obtained. Complementary color add to the complex color can make to a dark, even into a gray or black.
