Abrasive Paper is made of imported latex paper base and strictly graded silicon carbide abrasive processed by electrostatic sand planting process. The product has the characteristics of good water resistance, strong grinding and excellent wear resistance. Pressure sensitive adhesive sandpaper with advanced transparent double-sided tape, no residue, more convenient to use.
Metallographic Cutting Coolant has extremely strong cooling, lubrication and anti-rust properties. When cutting, lower the temperature of the sample to reduce the thermal impact of the sample. It has a cleaning and anti-rust effect on the sample. Increasing the lubrication performance and improving the surface finish of the sample can also increase the life of the cutting blade and prevent the cutting machine from being corroded.
The product is refined from imported raw materials. During the production process of printed circuit boards, in order to monitor the thickness of the coating in the PTH hole, the line etching side etching rate, etc., metallographic section microanalysis must be performed. It is a special chemical product for metallographic slice molding using acrylic resin as the main raw material. It has excellent properties such as smooth and fast curing at room temperature, few bubbles, no discoloration after long-term storage, high hardness, and acid and alkali resistance.
