Treatment agents

We produce agents for metal and water treatment.

Metal processing agent
The RINKA MCB Series consists of chemical polishes made of phosphoric acid mixed with a glazing agent and retardant of nitrous acid gas, which are used to polish aluminum and aluminum alloys. They compete with electro polishing in their performance. Although other kinds of acid, including sulfuric acid, are also used for metal polishing, phosphorous acid has the advantage of being able to produce a mirror gloss when the forming and solving of the layer of oxide are perfectly balanced.

Chemicals for water treatment
1. The RINKA WRC Series include agents for preventing cold and hot water supply systems from rusting, and retardants for controlling corrosion and formation of scales in heating/cooling water systems. They are extremely effective for the maintenance of watering systems, as they prevent corrosion of the equipment and formation of scales.
2. The RINKA WCP Series consists of cleaners to remove scales, iron rust and slime attached to the inside of the pipes for heating/ cooling water of air conditioners, heat exchangers and boilers. They enable reliable maintenance and energy-saving system operation. The product you select will depend on the scales in your systems.

<Chemical Polisher> Product Name Characteristics Metal Application RINKA MCB #1 Improves working environment because of low emission of nitrous acid gas or other toxic gases, reduces costs due to lower consumption of nitric acid, and shortens polishing time because of its high polishing performance that compares to electro-polishing. Aluminum / Aluminum alloy Bright finishing RINKA MCB #2 RINKA MCB #3 Prevents excessive polishing. Ideal for auto polishing. Aluminum / Aluminum alloy Bright finishing <Opaque Finishing Agent> Product Name Characteristics Metal Application RINKA MCB P#500B This agent outperforms machine finishing, because even objects of complicated shapes can be easily finished in opaque by soaking them it. Aluminum / Aluminum alloy Opaque finishing RINKA MCB P#700A Alkali etching <Coloring Agent> Product Name Characteristics Metal Color Application RINKA MCC #2 Even objects of complicated shapes can be easily colored in bronze, a color which suits the Japanese lifestyle. Stainless steel Bronze Metal fittings for houses (crescents/hinges), Home appliance parts, Pens <Surface Treatment Auxiliary> Product Name Characteristics Metal Application RINKA MCB Cleaner #50 Even objects of complicated shapes can be easily cleaned by soaking, with no erosion of their anodic oxide coating.
