Car  extra fast clear coat  is a clear coating of resin plus solvent, with resin as the main film forming material. The main harmful substances of automobile varnish are derived from solvents, which are generally benzene series, ketone series and ester series. The varnish has a large odor and does not represent a great toxicity. The solvent content is high, but the odor is small, the harm is great, the resin content is high, the smell is large, but the harm is small. The solvent in the varnish will generally evaporate during the drying of the paint film. Therefore, it is generally not a problem for paint practitioners to take protective measures during production and painting. Car  clear coat series  are classified by variety: they are divided into acrylic varnish, alkyd varnish, nitro lacquer, phenolic varnish, fluorocarbon varnish, and polyurethane varnish. Nowadays, the market mainstream automotive repair varnish is acrylic varnish. Compared with other types of ...

The last layer of car painting is spray clear coat, such as  BYT clear coat . Sometimes there will be varnish layer shedding phenomenon, if varnish layer can not hang color paint layer, it will directly affect the effect of the entire car, but also it has a certain impact on their brand reputation. In this case, it is recommended that all varnish be cleaned, then re-polished with fine sandpaper and then spray  clear coat . And varnish must be sprayed in strict proportion. If the next day is still lost, it can only be removed completely. The painting process is not recommended to be sloppy. This is a rigorous job. Think of your brand's reputation, so please treat each car carefully.

1.It may be spray paint after the direct  clear coat  did not dry. 2.It may be that the paint has been dried for too long. It will also be exfoliated if it is not polished directly. Because any paint must be polished before it is sprayed, the clear coat will be more firmly adhered to the primer layer. 3. Clear coat series  has a different solid content, different clear coat matching the corresponding curing agent, if the clear coat and the corresponding curing agent ratio is not correct, the adhesion will also have an impact. For example, if the curing agent content is high and the clear coat concentration is low, then the varnish clear coat layer will become brittle and tend to fall off when combined. Therefore, do not use clear coat, do not use curing agent at random, and use an appropriate curing agent.

Acrylic automotive  clear coat  belong to the outermost protective paint for automotive refinish with high gloss, high brightness and fullness and other characteristics. Different concentrations of car varnish prices will be different. For example, the market price of Maschine auto varnish, such as suit of  BYT clear coat series  (5 liters of varnish + 2.5 liters of hardener + 1 litre of hardener), the best set of high clear coat is 540 yuan, with high hardness and fullness, its quality can be comparable to imported clear coat. It is mainly suitable for high-end cars, due to high concentration, after the paint is recommended temperature baked, to increase the drying speed. The cheapest low-grade varnish is relatively cheap, and the set is 348 yuan, which is mainly applicable to low-end automobiles, trucks and other aspects. Each  clear coat manufacturer  will generally develop four or five different varnish for different customers. Of course, the price of...

1.Paint and primer spray gun sector contrast The top coat has a low spraying viscosity, requires fine atomization, and has a uniform color and fullness. Therefore, the nozzle has a small aperture, the spray nozzle atomizes to widen, and the spray spread is dispersed. The  primer paint  has a high viscosity and requires uniform atomization, smoothness, and easy grinding. Therefore, the nozzle has a large bore diameter, a large central area of the spray, and a concentrated spray pattern. 2.Differences between topcoat spray and point repair spray guns: The repair spray guns used for undercoat paints generally use mini guns with caliber between 0.8~1.2mm, and the spray width is less than that of top paint spray guns. While the paint has good atomization effect, it can effectively control the spread of paint mist. Eliminate paint defects. Viscosity: In general, the higher the viscosity, the thicker the paint, the lower the viscosity, the thinner the paint. Base paint: The base pain...

The first thing to know is that auto paint is that it is not a separate entity. It is a paint on the surface of a car. It is made up of different paint layers. Automobile manufacturers generally use one-component amino baking paint as the  basecoat colors  and top coat. Film-forming substances need to be baked at a high temperature of 170°C. to achieve the required hardness and adhesion, and the performance is very good, high gloss, bright and beautiful. The gilt metal plays a very good decorative and protective role. The main components are amino resins, hydroxyl resins, pigments, additives, solvents and so on. Need to be sprayed through multiple processes. Another type of  auto paint  is automotive refinish paint. If the car is opened for a long time, if the paint is scratched, auto repair paint is needed. The paint is acrylic paint. The main components are acrylic resin, pigment, auxiliaries, solvents, etc. It is formulated to have excellent weather resistance, ...

The automobile coating has two important functions, one is to protect the matrix material (such as steel and plastic), and the other is to improve the appearance quality. Coating is effected by a film of about 0.1 mm, which is very effective compared to other methods and measures. The overall process flow in the automotive paint shop is divided into two major steps: The first step: starting from the body-in-white, pre-cleaning, pre-degreasing, degreasing, washing, surface modulation, phosphating, invading washing, spraying, electrophoretic coating, ultrafiltration spraying and ultrafiltration infiltration, electrophoresis baking, electrophoresis Grinding, PVC, squeeze sealant, wipe. The main purpose of this step is to protect the substrate material from corrosion. The second step: spray painting, middle coating baking, polishing, wiping, artificial spray  solid colors (basecoat colors) , robot spray  pearl colors(basecoat colors) , robot spray paint varnish CC, drying paint,...

1.   Extra fast clear coat  is commonly used varnish in  BOYET series .  VOCs and other gases that are originally dissolved in paint and paint mist treatment circulating water will be released during spraying, wet defoaming, paint film curing, and paint residue treatment and reuse. These environmentally harmful gases need to be released. After being collected and oxidized, it can be discharged into the atmosphere. The harmful effects of VOCs on human health in paints have been studied recently. Some of these emissions can be classified as greenhouse gases that affect global warming. Controlling and reducing the production of greenhouse gases and the release of VOCs by effective oxidative treatment are another important topic, referred to as VOC and greenhouse gas emissions issues. 2. In order to ensure the final product, a painted vehicle body meets or exceeds the requirements of the automobile manufacturer and satisfies the customer's expectations, and it is neces...

1. MF1K solid colors (basecoat colors)   are commonly used primers in  GOODSIF  series  auto paints. After the body is painted, the wet film on the car body surface needs to be dried or cured. The drying process is usually carried out in a drying room with infrared or hot air convection. Consuming the least amount of energy to cure the varnish on the car body surface to obtain the highest quality coating product is another important topic. It is called the dryness rate of the coating surface, which is related to the environment and coating quality. 2. Paint slag produced by the overspray capture system will be collected and processed. Some of the paint and purified water components will be recycled and reused. Others will be treated as waste residue. The use of the best costs for recycling or recycling as much of the constituents of paint waste as possible and safe and environmentally friendly treatment of waste slags are another important topic, referred to as was...

1. The painting system can be thought of starting from the spraying of paint on the gun to the surface of the car body, but after the paint is atomized by the spray gun, only part of the paint is actually applied on the car body surface. Whether it is  epoxy primer   or  clear coat series  or other paints. The ratio of the amount of paint applied to the vehicle body surface to the total amount sprayed by the gun is defined as the paint application efficiency. 2. The coating efficiency about 50%~60% means that the remaining 40%~50% of the overspray must be captured before being emitted to the external environment. Due to the large amount of paint used, the use of water treatment or wet purification systems is the preferred method of capture. The ratio of the amount of overspray paint captured to the total amount of paint entering the capture system is defined as overspray paint capture efficiency.

Automotive white pearl, one of the  pearl colors(base coat colors) , paint using three processes: white base coat+ pearl + varnish. White base coat: White pearls being good or not, depends on the white background; the smoother and more delicate the white base coat, the less likely the white pearls will be spent. White base coat generally use 1K pure white, that is, one-component white paint, thin material diluted a little, wet spray two times, each time blow dry, do not throw the gun, the smoother the better. Be careful not to use poor quality thinner , otherwise it will look very numb. White Pearl: The pearl is also a dilute point, and it is spread evenly twice, that is, it floats twice. Note that the gun should be uniform. Cover varnish: It is also two times, the first time can be used fog spray, to prevent bite the bottom, not too thick, there is a little light, the second time we must spray, emit light brightness, take the gun to be uniform, check the flatness and fullness, i...
