21 questions about water-like paint are answered here!

Many people do not know enough about water-resistant paint, think that water-resistant paint in terms of performance is not as good as traditional oily paint, in fact, this is a big misconception, water-resistant paint not only in environmental protection is much higher than traditional paint, in terms of performance, such as adhesion, yellow resistance, water resistance, etc., is not worse than traditional oily paint, today's small editor on one by one to answer questions about water-resistant paint.
about the water-like paint big crack
1, water-like paint adhesion how?
adhesion is better than oily paint (excluding low-quality water-resistant paint), normal temperature drying quickly, and has excellent rust protection, corrosion resistance, excellent weather resistance.
2, why is water-resistant paint more yellow-resistant than paint?
because the water-based paint film does not contain yellow-prone substances, and oily nitro contains a large number of nitro cotton, PU contains a large number of TDI and other yellow-prone substances
China
.
3, water-like paint is very flexible?
softness of the water-based paint is incomparable to the paint, because the water-based paint film is almost all pure resin cross-linked, and nitro contains a large number of nitrification cotton, PU contains a large number of very easy to break the chain of TDI.
4, water-like paint will cause wood cracking?
, in a sense, it is easy to achieve a certain anti-cracking function.
Wood has hydro-hydrogenic properties, nano-scale water-based resin can seep into the material with the wood catheter to a certain depth, drying and curing, these seepage resin can be well glued wood fibers, should play a role in slowing wood cracking, rather than water-based paint coated furniture will be more prone to cracking.
5, water-like paint will improve the water content of wood?
No, as follows:
(1) Wood moisture content and wood moisture content calculation:
to a piece of 1M x 1M, thickness of 1CM solid wood calculation, the general furniture enterprises used solid wood in the processing water content of 12% (water content of wood moisture weight, and the weight of de dried wood percentage).
(2) Water content after wood is coated with water-based paint:
theory is calculated as follows, with 40% water-based lacquer solidification (i.e. 60% of which is water), 10m2/kg of artificial spraying and spray utilization rate 40% (higher) calculation, equal to the amount of water sprayed into the wood is 24g/m2, after spraying the natural drying process, about 50% of the water will evaporate externally, wood adsorption of water about 12g/m2.
(3) wood once the first layer of coating film closed, the second layer of sprayed water can not enter, unless the first layer of primer is not waterproof.
(4) wood on the positive surface of the actual water absorption is very poor, moisture into the wood is mainly the end, if the furniture manufacturing process to be closed as early as possible, the water content of the wood is more difficult to change.
the hardness of the water-like paint to 6?
hardness HB to 1H of a single part, equivalent to nitro paint, and the hardness of two parts 1 to 2H, i.e. equivalent to PU paint.
: Some single-group products with a certain amount of hydroxyl, such as the use of adaptive curing agents, often can improve an HB hardness
7, water-resistant paint cold water?
poor cold water (the vast majority), will white shadow, bubble or seep in, etc. , good cold water (very few).
8, water-resistant paint resistant to 100 degrees C boiling water?
(most of them), will white shadow, bubble or seep in, etc. , good no response (very few).
9, water-resistant paint acid and alkali resistance and other protective?
can pass the same test as oily paint, some items are better than oily paint, such as alcohol-resistant.
10, water-like paint can do oily paint luster?
light less than a point, such as a single-group water-like paint can reach 8 minutes, two-parts can reach 9 minutes, but matte can be more dumb than paint.
11, water-resistant paint weather resistance, resistance to newness?
is much better than paint, about twice as much, because the resin cross-linking of water-based paint is not the same, so when used in outdoor painting, water-based paint than paint advantages more obvious.
12, water-like paint has a stronger permeability to wood?
, wood is hydro-hydrogenic, and the resin of water-based paint can easily seep into the wood and bond the wood fibers, which will help the wood to resist cracking.
13, water-like paint can have the clarity of oily paint?
, of course, also look at the clarity of the resin itself and cross-link density, etc. , the paint powder will also affect the clarity of the paint film.
14, water-like paint smoothness or feel?
good, the same as oily paint, but also the same as oily paint.
15, why is the water-like coating film a more consistent coating film of wood?
because the water-like paint film is a wrinkled film, oily paint is a balance film, water-like paint can more meet the deformation of wood around the clock.
16, the rapid hardness of water-like paint slower than oily paint does not mean that the water walks very slowly?
No, in fact, water-like paint coating, moisture in front of the packaging almost evaporated, fast hardness is slow, because additives such as water-like plasticizers evaporate too slowly caused, such additives than oily similar substances much slower.
17, why is the water-like paint film getting harder and harder?
because as some additives evaporate, water-based resins adhere to each other, will be more and more tight, naturally the paint film hardness is getting higher and higher.
18, water-resistant paint wear resistance represents hardness?
does not represent, but there is a certain relationship, high hardness can improve scratch resistance, but wear resistance may be related to film quality, how much water wax added.
is there so little dust when it is polished with water-like paint?
because the resin has better hydro-hydro-hydropronity than oily resin, flying dust easily absorbs moisture from the air and sinks, so the use of water-based paint will appear to be particularly clean air.
20, water-like paint can not be polished with water sandpaper?
Because the water sandpaper is mainly used for the operation that needs to be polished with water, sanding methods and powdering methods are also different from dry sandpaper, sanding is particularly prone to heat, its own water-based paint film resin is more, more susceptible to heat backplastic, coupled with water sandpaper powdering capacity is poor, resulting in easy sandpaper.
21, water-like paint closed?
Very good, when water-based paint film to a stable period, its permeable wood fiber resin and surface resin will be closely linked, and will not be slightly cracked by the creep of wood, will have a better than oily paint closure, of course, the use of poor resin is not included.
