Do you generally choose a thinner or slow drying water in painting?

Choose a diluent according to the different temperatures Slow drying water In general, we all know very well that when the temperature is very low in winter, choose a winter diluent with a faster volatilization rate, and choose a summer diluent with a lower volatilization rate when the temperature is slower in summer. It is more difficult to grasp that the temperature is in the range of 20 5. In general, we recommend using a summer diluent if it is higher than 20, and a winter thinner if it is lower than 20.

However, due to the different operating habits of spraying workers, the shape and size of the work are different, and the thinner used may be different, which requires our distributors to have two kinds of diluents in this temperature range, winter thinner and summer thinner, which complement each other. When the winter thinner dries too quickly, you can switch to summer thinner or use part of the summer thinner to reduce the volatilization rate; When the summer diluent is too slow to dry, you can switch to the winter diluent or combine part of the winter diluent to improve the volatilization rate. At the same time, there is another advantage of the dual-purpose thinner, the temperature is sometimes high and sometimes low, and the change is not completely regular, when the temperature changes suddenly, it can meet the needs of customers.

When the temperature is particularly high, or spraying large workpieces (such as 35) in a high-temperature environment, it may be necessary to add slow drying water, the addition amount is 5 30% of the diluent, at this time, the amount of diluent can be appropriately reduced, to avoid the viscosity is too low, slow drying water should not be added too much, otherwise it may lead to soft paint film.

Dear, hello, I am glad to answer for you that the paint high temperature thinner is slow drying Therefore, different coatings have different thinners, the same coating, because of the different seasons and climates, the composition of the thinner is also different, such as in summer, the paint thinner is adjusted to dry more slowly, and in winter, the paint thinner will be adjusted to dry a little faster. Dilute the paint with a slow-drying thinner to adjust the drying speed. Reduce the temperature of the surface of the trembling god and increase the dilution when adjusting the paint, that is, increase the thinner appropriately.

Generally, the nitro paint dries quickly, and the thinner the spray, the faster it dries, so if there is a problem in the spraying process, it must be dealt with quickly, otherwise it will be difficult to do after curing, and it can only be polished.

Curing agents are relative to two-component paints, coatings or glues, which are usually composed of a combination of A and B materials, which are mixed in proportion when used, and the viscosity does not change after mixing, and it cures naturally under the condition of specified temperature and humidity. Generally speaking, the higher the proportion of curing agent, the faster the curing speed, and the higher the hardness after curing, and it is not recommended to use it in excess of the ratio. Common materials with A and B components are:

Acrylic glue, two-component epoxy glue, two-component polyurethane coating, etc.

The diluent is a solvent that reduces the viscosity of the material for convenience, and there are different or special diluents for different materials, and the diluent is volatilized and evaporated after the construction is completed. Common diluents are: water, xylene, banana water, ethanol, etc.

The effect of paint slow drying agent is the opposite of the curing agent, in order to prolong the curing and drying time of the material and the added ingredients, the viscosity remains unchanged after mixing with the raw material, and is used for printing and publishing or wall decoration The final effect is used, and the common ones are coking benzene.

Thinner is to dilute the viscosity of the paint, and the appropriate viscosity is convenient for construction operations.

The solvent composition of the fast-drying diluent is different from the slow-drying diluent, and the fast-drying contains low-boiling components such as methyl and ethanol (50 70°); Slow drying contains high boiling point components such as ethylene glycol monobutyl ether (164°).The two-component of automobile paint is generally PU or PE, and only special thinner can be used to favor slow-drying thinner, not fast-drying thinner. Because it is necessary to ensure that the paint film has a certain time to dry and solidify, it is convenient for the soft and hard bond reaction and the surface has enough time for self-leveling.

The standard surface dry is less than 4 hours, and the dry is less than 24 hours.

The hardener is classless and accommodates the master paint and thinner. Where is the quick-drying curing agent you talked about?

The curing agent is essentially aliphatic amines, which are added to the main paint in a certain proportion to achieve the standard of not fast or slow drying, and it is common sense to dry quickly if you add more. I have never seen a "fast-drying curing agent" before, and its birth is nothing more than a large solid content, charging consumers a little more money, and adding more to dry quickly.

Because it is necessary to ensure that the paint film has a certain time to dry and solidify, it is convenient for the soft and hard bond reaction and the surface has enough time for self-leveling. The standard surface dry is less than 4 hours, and the dry is less than 24 hours. If it dries too quickly, the paint will blister and the flatness of the paint film will not be good.

The quick-drying curing agent is added when the weather is cold, in order to allow the car paint to dry. The principle of car paint is that it dries slowly and has a good effect. If it dries quickly, there will be some adverse reactions.

In the same way, if you want to dry slowly, you can add less "fast-drying curing agent".

You didn't buy a "fast-drying curing agent" for fast drying, why do you want to adjust the slow drying?
