The range of application of epoxy is basically in the ground floor such as pharmaceutical factory, workshop, ground treatment , followed by metal surface corrosion protection. From another point of view, polyurethane coatings are mainly used in the civil field, industrial areas also have.
And epoxy coatings are basically applied in the industrial field, civil, it can be said that there is no basic.

Lighting industry to do the lamp rack, there are many resin materials used, I ask what kind of material in the end, what are the advantages? Synthetic color. Natural color.
Use plant resins and other materials that repel dust and bacteria. Mix the enamel paint with a mixing stick and dip the brush into it and remove the excess paint. Then start painting in the center of the room and exit. This allows you to focus on the most visible areas of the surface first.
If necessary, apply a new layer after the first layer has dried. Synthetic enamel paint is cheaper due to paint mixing. Usually, when mixing synthetic nail polish, all you need is the main color and a reduction. This acrylic enamel blend is much more durable due to the hardener added to the blend. The difference between paint and paint is the same as between a car and a Ford, because paint is a type of paint.
The paint is usually based on acrylic, water or oil. It is the oil-based paints that are traditionally called enamel, but these days it is possible to get water-based or even latex-based glazes on the market. Synthetic polymer is a generic term that can refer to acrylic paint, vinyl acrylate PVA , styrene acrylic, etc. Enamel paint is a paint that dries to a durable, usually glossy finish and is used to coat surfaces that are outdoors or otherwise subject to wear or temperature changes.
Not to be confused with enameled objects, where the paint is applied to the glass with a brush and baked in the oven. Synthetic thinner is a solvent that improves the viscosity-regulating properties, as well as the drying and curing times of paints and pool coatings. Improve paint application. Two-component paint also called 2K paint is a paint in which the paint hardens through a chemical reaction.
Two-component paint hardeners are typically polyisocyanates which, in combination with primers, form very strong coatings. There are ingredients, fillers and materials to make cellulosic coatings. It is a short oil alkyd resin which is used as a binder in the mixture, bentonite, calcite and talc as a filler, acetone, pigment powder for paint, isobutyl acetate, solvent derivatives, etc.
Vinyl esters are often referred to as linings. The world "lining" in the coating industry is commonly defined as a material used to protect the inside surface of a tank, vessel, or similar structures from highly corrosive or potentially highly corrosive environments.
Vinyl esters are normally two-component coatings applied at normal temperature. They are usually applied in thick coats 2 x microns. The vinyl ester coatings have rather short pot life and should therefore be applied with two-component airless spray equipment. Benefits Very fast curing Very good adhesion Very good abrasion resistance Very good chemical resistance Very good solvent resistance Can be applied with normal airless spray Glassflakes improve abrasion resistance Limitations Short pot life approximately 45 minutes Overcoating interval: min.
The main reason for applying a zinc containing coating is to have a primer with the ability of providing cathodic protection. This will contribute to protecting the steel substrate and reducing the risk of having undercutting corrosion. They are very resistant to different chemicals and especially solvents. Zinc ethylsilicate solvent-based and alkali silicate water-borne are also often used inside storage tanks for solvents because of the extremely good solvent resistance. Inorganic zinc coatings have, generally, not been used for services implying continuous water immersion.
Typical practice in the use of inorganic zinc coating systems varies with the exposure environment and type of structure. One coat of inorganic zinc, typically microns DFT, is often used for tank lining. The water-borne zinc silicate has to be applied with conventional spray.
The solvent borne zinc-ethylsilicate, however, is excellent to apply with airless spray. Careful monitoring of the relative humidity is important during application and curing. Multiple topcoats over inorganic zinc coatings are used for offshore structures, ships, industrial plants, refineries, tanks, bridges etc.
Benefits Very good solvent resistance Very high heath resistance max oC Very high mechanical strength Very good adhesion to blast cleaned steel Relatively good re-coatability Limitations Requires humidity for curing 2-pack Max. They offer very good airless spray application properties, are quickly recoatable, and show excellent compatibility with most coatings except alkyd: saponification. It is a good primer for multicoat systems, both for new constructions as well as for field maintenance applications.
Zinc epoxy is often used as a holding primer both at industrial plants during maintenance and within shipping. It is quick drying and the overcoating interval is relatively short. It has very good adhesion, good impact resistance and is heat resistant up to approx. The abrasion resistance is good. The disadvantages of zinc epoxy compared with inorganic zinc is first of all that the galvanic protection of the steel is limited as the electrical conductivity of the binder is low.
Secondly, the acceptance level of chlorides on the substrate is lower. This is particularly a drawback for marine exposures.
Benefits Good corrosion protection Good adhesion Good mechanical strength May be overcoated with all types of paint, except alkyds Chemically curing Short overcoating time Limitations Temperature dependent 5oC Two-component DFT: microns microns for underwater use Dry heat resistant up to oC Not acid and alkaline resistant resistant at pH range Technical info Generic types of paint.
Generic types of paint Detailed description of various types of paint. Alkyd paints Alkyd paints are made from alcohol and acid. They are mostly used for decorative purposes and for protection of steel exposed to relatively mild environments. Vinyl coatings are widely used as industrial coatings in chemical plants, refineries and tank farms, bridges and on ships.
Use Vinyl coatings are physically drying. They have been widely used as industrial coatings in chemical plants, refineries and tank farms, bridges and on ships vinyl tar under the waterline.
They are one-component paints, and as such they are easy to apply by airless spray, brush and roller. It is, generally, not recommended that vinyl coatings are subject to long time exposure to temperatures exceeding oC. Decomposition would then take place and lead to yellowing and brittle paint film.
Many dissimilar paints can be placed under the umbrella "vinyl coatings". The reason for this being that vinyl coatings can be formulated in many different ways. They can be based on various vinyl resins and modified with other binders etc. Therefore, vinyl coatings may differ greatly from one manufacturer to the other. Benefits Good chemical resistance Good water resistance Quick drying Not temperature dependent One-component Limitations Low solid content Poor resistance against strong solvents Dry heat resistant up to approximately 80oC High content of volatile organic compounds VOC.
