The difference between underwater furniture and oil-based furniture!

Water-based wood paints are currently divided into single-component water-based paints and two-component water-based paints.

First of all, let’s discuss what is pure water-based surface coating, that is, the primer and topcoat must be pure water-based paint with no thinner, no alcohol, and only water.

Similar to this kind of pure water-based surface coating, after the water-based primer and water-based topcoat undergo thermal expansion and contraction in spring, summer, autumn and winter, the film stretchability remains the same, and the paint film will never be stripped between the coatings.

Let’s talk about oil-bottom water surface and pseudo-underwater surface coating.

The time is longer or shorter.

Or use the blade to cut diagonally to see if the water-based primer can be peeled off for testing, or take a long strip of transparent tape and pull it hard to test whether the paint film can be pulled off?

If it is an oil-based water surface or a pseudo-underwater diluted with alcohol, as long as the odor is great when the room is not ventilated, it proves that the solvent content is large, the odor problem will still exist after installation, because the pure water-based primer is waiting Even if the dry room is not ventilated, it will not smell any paint, and the owner can move in with peace of mind after installation.

Therefore, this oil-based water surface process is also very risky for later odor problems, potential paint stripping, and whitish hair.

In view of the above problems, let's talk about the principle of wood shrinkage.

In addition, the ductility of the oil-based paint and water-based paint mentioned above after thermal expansion and contraction in spring, summer, autumn and winter is also different, because the ductility of oily and water-based is different, if you add the different woods mentioned above The coefficients of expansion and contraction are also different, so under the pulling force of the two, the oil-bottom (pseudo-underwater) surface furniture will experience the following situations when it undergoes spring, summer, autumn and winter, thermal expansion and contraction, and a large difference between wet and dry conditions: The adhesion between the layers is not strong, resulting in poor adhesion, and the layers are peeled off each other, and even the whole piece can be torn off like a mask.

Compared with pure water-based furniture, the biggest difference between pure water-based furniture and oil-based water-surface furniture is that the construction has no smell.
The color, primer and topcoat are all water-based, and the paint film has the same ductility, and the paint film will not turn white.
Mongolia will not delamination.

Oil bottom water surface [including oil character Lise, underwater surface, pseudo-underwater surface, and PU bottom surface] Although I played the edge ball, I luckily avoided environmental monitoring, but after the furniture was used for half a year to two years, or the humidity and temperature appeared to be relatively high.
When there is a big contrast, its disadvantages will continue to show up.
Then there will be the phenomenon of peeling between the coatings and anti-whitening as mentioned above, which will result in later quality complaints, which is not a small disaster for the furniture factory.

In contrast to pure water-based furniture, since no solvent is used as a dispersion medium, environmental protection and construction odor are not a problem.
Moreover, most of the water-based primers for pure water-based furniture are composed of film-forming substances, fillers, and additives, which are used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, and provide anti-corrosion functions.
At the same time, it can ensure the uniform absorption of the topcoat, so that the topcoat can exert the best effect.
The water-based primer can comprehensively improve the quality of the coating film and penetrate into the wood pipe to be firmly sealed, making the water-based topcoat easier to color and more outstanding in color.
Its leveling, color sealing, sealing performance is good, and water resistance is good, avoiding the appearance of series of problems such as tendons and discoloration.

Having said so much, in fact, to illustrate one truth: the transition from solvent-based wood coatings to water-based paint requires a lot of work.
For example: it is necessary to stop using solvent-based paints, and even for the base rubbing color, you cannot use oily liss and oily fillers with great odor.
If you want to paint pure water on the bottom and water surface, you need to pay attention to the water paint as a whole, such as The working environment and the painting process can truly implement the "oil-to-water" painting.
