The loop resistance tester is designed by combining high-frequency switching power supply technology and digital circuit technology. It is suitable for measuring the loop resistance of switch control equipment. The test current adopts DC 100A and 200A recommended by national standards. The loop resistance can be directly measured at a current of 100A or the loop resistance can be directly measured at a current of 200A. The final test results are all displayed in numbers.
skills:
â’ˆ Loop resistance tester is connected according to four-terminal connection method.
â’‰ Turn on the power of the loop resistance tester.
â’Š The loop resistance tester can press the measurement key (for example, after the current display A value is less than 100A, it can be corrected by the panel current fine-tuning).
â’‹ After measuring the displayed value, you need to save the data.
⒌ After measuring, please turn off the power.
â’ Please take care of the test pliers.

Matting Agent For Leather Coatings
Introductions
Matting Agent specialized used for the PU/PVC matte finish leather coating. It is a micronized precipitated silica matting agent for both solvent-based and water-based system. The special Paint Matting Agent can be applied to different resin systems.
It can be not only improve the haze of leather coating, but also the Original color of the coating. In focal system, it shows beautiful white degree, after polishing transparent feeling strong, treatment against with color more vivid. It also features good leveling property, and will not produce agglomerate or precipitation.
Feature
1, Easy to Disperse. The matting agent can easily disperse in both solvent and aqueous solution.
2, High Matting Efficiency: It can reduce the gloss for the surface of leather, provide the better matte finish.
3, High Transparency: Fine control of the particle size and particle size distribution, and gives better transparency for leather coating.
4, Excellent hand feeling.
Application
Leather surface coating, PU/PVC matte finish leather coating, solvent-based or water-based leather surface coating.
Strengths
1, We are the largest production of silica gel in China, and focus on Paint/Coating Market about 25 Years.
2, We are the realizable supplier for some international company and export to many countries. Such as AkzoNobel, Valspar, Nippon Paints, Dgl Camel, Taiho Paints and PPG.
3, We have strict control of the batch quality, the physical index and performance are strictly tested before delivery. Will ensure that stable products of different batch.
