KRB-604 water-based antirust agent is a compound mixture of antirust additives, preservatives, etc., which does not contain phosphorus, lead, chromium and other chemicals, and is safer for the environment and human body. It is used for short and medium-term anti-rust treatment of ferrous metals, with good anti-rust effect and simple and easy to use.

1. Purpose

It is KRB-604 suitable for short-and medium-term processes and inventory anti-rust treatment of metal parts processing and manufacturing industries such as automobiles, motorcycles, locomotives, refrigeration and air conditioning, compressors, diesel engines, gasoline engines, electronics, electrical appliances, home appliances and other metal parts processing and manufacturing industries and their supporting enterprises; it is also applicable to the short and medium term anti-rust treatment of various machinery and equipment of industrial production enterprises in the maintenance process of steel (carbon steel, alloy steel, cast steel, etc.), iron and other ferrous metal materials and parts.

2. Performance characteristics

A. The KRB-604 has excellent anti-rust effect and meets the short and medium-term process and inventory anti-rust requirements of ferrous metal materials, parts and components;

B. Metal parts can be protected against rust by single-position dipping, brushing or spraying, and metal parts can also be protected against rust by pipelined dipping or spraying;

C. The anti-rust period is different due to the difference of environmental temperature, humidity and corrosive components. Usually, the anti-rust period can reach 1-3 months. This product can be used at room temperature, and the method is simple and easy;

D. use cycle is long, fatigue does not need to replace the liquid, the appropriate supplement can be;

E. This product in the shelf life, does not occur precipitation, deterioration, rust resistance and other phenomena; transportation, storage, safe and convenient.

4. Method of use

According to the production process of metal parts rust requirements, by the test to determine the effective and reliable process, operating procedures, ring.

environmental regulations, quality control procedures, etc.

A. Before using the KRB-604, clean the oil film and dirt on the surface of the rust-free parts;

B. KRB-604 anti-rust agent according to the specified amount into the appropriate container (such as carbon steel anti-rust 7 days according to 1:3-5 times water, anti-rust 15 days according to 1:1-2 times water, anti-rust more than 1 month recommended with the original solution). Dipping, brushing or spraying shall be carried out according to the process procedures determined by the test; natural cooling, air drying or drying process shall be carried out for the anti-rust parts according to the anti-rust requirements and process regulations;

C. Put the anti-rust parts in the appropriate place according to the regulations; Implement the follow-up process according to the production process requirements of the parts;

D. if fatigue KRB-604, this liquid does not need to be replaced, and stock solution can be added appropriately.

5. Precautions

A. A small amount of leakage can be dried with a mop, and a large amount of leakage can be absorbed or collected in a container and poured into the chemical sewage system;

B. avoid long-term contact with skin of antirust agent; products splashed into the eyes, immediately rinse with plenty of water, serious untimely seek help from a doctor; such as drinking the entrance by mistake, you need to repeatedly drink a lot of water and spit it out or go to the hospital for treatment; avoid direct contact with children, or even take it by mistake;

C. Storage should avoid mixed storage with food, feed, etc., to prevent the intrusion of dust, acid, etc.

6. Product validity: two years.

7. Packaging and storage: 25kg, 200kg plastic barrel packaging; Tighten the lid and seal it and store it in a cool place. Pay attention to leakage; The remaining products are sealed and stored, and avoid contact with children.
