Paint (paint) adding crosslinking agent

Paint (paint) adding crosslinking agent,General component is PU is the most commonly used paint, furniture paint and c west acid paint. We are a lot of people say not the lacquer that bake, is refers to the furniture lacquer furniture. Because the paint is dry type, the cost of this kind of paint is cheaper.

And c west acid lacquer was first used for auto exterior covering parts of the motorcycle, but now do good furniture paint also adopt this kind of practice, this is the lacquer that bake. The hardness of the lacquer that bake to 2 h, finish good, pay for power, subsidence is small, acid-proof sealed ability strong, resistant to yellow surface is better. This kind of paint is + crosslinking agent, paint thinners. Now say the authentic of the lacquer that bake, is refers to the car paint.

Compared to PE and PU is different, is made up of paint + initiator, promoter + thinners. This kind of paint hardness is stronger, more than 3 h, better brightness texture, excellent resistance to yellow face. Of course the cost of this kind of paint is also high. Generally refers to the diamond, diamond paint is refers to this. The other, in PE class and there's a film coating, the paint cost cheap, poor pay for function.

UV paint, the paint is not the lacquer that bake, nor from the paint, but a light crosslinking paint. By ultraviolet irradiation crosslinking moment. UV lacquer is only refers to the surface of the layer, the inside or the PU furniture paint (light) in the past, the cost of the paint is similar to c west acid lacquer, because it is furniture paint and because of this paint is instantly crosslinking, without volatile material.

But this kind of paint process even more. UV lacquer on many performance can achieve the result of PE, such as the hardness to 3 h, the brightness is not good. But the UV paint also have disadvantages: 1. UV lacquer on the sides of the paint can't, so I can't paint, can seal through article sealing side. And do lacquer spanner is not moistureproof board, but the density board. Sealing side slightly bad would be easy to deformation risen. 2. Because it is the PU paint, UV is outside, pay of 2 different paint force is not very good.




Chinese name: Diethyl toluene diamine(DETDA)

A reagent grade additives


NC, this kind of paint now basically there is no use, so much is introduced. And sanded paint, matt, but the strongest scratch resistance capacity. U v lacquer refers to the paint process USES a light crosslinking paint, Pu paint is used in polyurethane paint. U v paint and Pu paint is the main difference between its different technological process, some light crosslinking have get together ammoniac fat lacquer paint.

U v paint light crosslinking technology adopted by the pollution-free during spray paint, more environmentally friendly than Pu paint, said on the technology of processing from the factory floor, the protection of workers' health and the environment is good, from the production point of view, it is a kind of upgrade products. However, for buyers, the product has set up a file in the processing of the floor, the paint of solvent evaporation, whether U v was produced by light crosslinking technology paint floor, still use the traditional craft production of Pu lacquer floor, will not constitute a pollution hazard to the user.

From the use of perspective, it's hard to say which the paint the floor better. From the craft, says U v paint gloss better, but not absolute, it often depends on the state of the art workers; U v paint and Pu paint wear resistance is very good. Hong remind buyers, to prevent the floor paint surface pollution, mainly in when buying a floor board to see if the paint of the floor completely dry, if paint is dry, and there will be no problem.

Up the cause of the "heat rash" is generally not volatile paint is too thick, workshop temperature is too high, crosslinking agent adding too much of these reasons. Crosslinking agent generally in accordance with the paint specification to allocate. Can't disorderly adjustable ratio.

The paint of paint white refers to the humidity is too high, paint volatilizes quickly so produces atomization phenomenon, is generally going to add a little water proof (slow dry water) to solve the problem. Generally no more than 10%.
There are "technology refers to the" drawing "" Joe wood craft, wood craft, do break in wood fiber board in the ducts. Imitation solid wood coating process.
