Hydrophilic coating crosslinking agent

Hydrophilic coating crosslinking agent, hydrophilic crosslinking agent is added in the wood coatings: although one-component aqueous dispersions provides the required performance, by adding cross-linking agent, the chemical media resistance, adhesion, or other performance may be further improved. There are several kinds of chemicals are available - nitrogen heterocyclic propane, gathering two imide and water can be dispersed carbide isocyanate.

Nitrogen heterocyclic propane and gathering two imine provides easy dispersed carbide and the performance of the low viscosity, but is sensitive to pH value, for they must respectively with acidic functional groups of crosslinking.

The first generation of more hydrophilic modification after the isocyanate, thus can provide easy dispersion. This option is usually isocyanate content is low, and high viscosity.

The second generation of isocyanate is more without solvent and after modification, is another kind of enjoy patent technology. One advantage of this technology is a high content of isocyanate (23%) and very low viscosity, make its have the ultra low VOC paint can be made.

Remember this is very important, this helps to ensure that the best coating formulation, should consider when choosing crosslinking agent used in polyurethane dispersions and end-use.

Wood floor

The researchers conducted a resistant black heel impressions (BHMR) test, the test is used to evaluate the shoe can be removed, it is an important test for wood floor. For this purpose, coating wear resistance is also very important (Taber abrasion test). They should also be enough hard (rocker hardness), because if the coating of soft, dust will be sucked in, which can lead to unwanted dirty mark.

The market's performance is an important chemical medium (stain). Kitchen cabinet manufacturers association (KCMA) is the main test of the market need for coating exposed to these medium such as mustard, coffee, and vinegar. After a period of time, to remove medium to see if it will be dyed. It is also important for hutch ark excellent abrasion resistance (Taber abrasion test) and excellent resistance to polluting (rocker hardness).

furniture

Excellent resistance to pollution, rocker hardness, wear resistance (Taber abrasion test) and resistance to water (water) is the most important furniture coating performance. In addition, excellent resistance to chemical media (stain), such as resistance to shoe polish, nail polish, soft drinks and other medium in office environment often see also to identify as the important judgment standard office furniture coatings.

Interior Windows and doors

In addition to the excellent water resistance and chemical resistance, good anti aging time is indoor coating needs important consideration for the Windows and doors.

Outdoor wood

As expected, excellent weatherability - including good optical, not broken, not pulverization, not burst or yellowing - for outdoor wood coatings market is one of the most important.
