Products Description
Introduction
KT-621M01 is a thermoset epoxy powder coating that protects pipes from corrosion in harsh working environments. The product has excellent high temperature resistance, excellent acid and alkali resistance, and good adhesion to the substrate. The coating will not fall off when immersed in hot water below 80℃ for a long time, and can be used for anti-corrosion of the inner wall of hot water pipelines.

Application
Operation Process
1) Remove oil, rust and other loose deposits, moisture, etc. on the surface.
2) Sand blasting or shot blasting to Sa2.5 level, anchor pattern depth 60⁓100μm, dust removal on the surface to near white level, pay attention to adding new and old sand evenly to make the ratio stable.
3) Thoroughly clean the surface of the pipe.
4) The special primer for spraying is required to be sprayed evenly and the spray thickness is below 25μm. Note that the thickness of the primer should not overwhelm the depth of the anchor pattern. (Note: This process is a recommended process. If conditions permit, you can spray primer, and the anti-corrosion effect is better)
5) Preheating, put the pipes sprayed with primer into the heating furnace to preheat, generally controlled at 175⁓190℃.
6) Coat the powder coating on the inner surface of the pipe with a thickness of more than 250μm.
7) Put the sprayed steel pipe into the heating furnace and cure at 200±10℃ for 20-40 minutes (according to the gel time) to make the coating reach the best state.
8) Test the coating performance after the coating is naturally cooled.

Storage
1. The product should be stored in a cool, ventilated, dry room with a temperature below 25°C and a humidity below 60%.
2. Keep away from fire and heat insulation.
3. The package can be opened at any time, and it should be sealed in time after use to prevent the powder from being polluted and damp.
4. Minimize the number of movements and avoid impact and pressure.
5. The stable storage period is 12 months.
Note: Improper storage conditions can easily cause the epoxy powder product to deteriorate, agglomerate and become unusable.

Company Profile
Guangzhou Kinte Powder Coating Industry Co., Ltd. is a joint-stock company, which was established by China Electrical Apparatus Research Institute (CEI) for the purpose of industrializing technological production. Early in 1960s, CEI began to study and develop the powder coating and its popularization. Our company was founded in 1992 and we produce seven series of powder coatings, such as pure epoxy, epoxy/polyester, polyester/TGIC, polyester/primid, polyester clear powder, acrylic powder and polyurethane.
Our company has complete sets of product lines and measurement equipment imported form Switzerland, Germany, Great Britain and USA, including Quantec-50 and PCS-70 production lines which are the newest types from BUSS company and our annual throughput is 20,000 metric tons.
Our company is the vice-direct unit of Chinese Powder Coating Specialized Committee. For many years, our company has been continuously devoted to the Chinese powder coating technical research and development and has made significant contribution to the Chinese native powder coating development. Apart from powder coating, we also have pretreated products, raw materials (powder coating, paint and polyester resin), outfit equipment (spray production line, galvanizes production line and laboratory) and start-to-finish service comprehensive superiority. Our high quality products and super technical service have gained the recognition of customers and our products sell well all over the world including US and Europe markets.
