Antifreeze RJK

Radiator protection, coolant additive concentrate (Colour: darkblue)

Customs no.: 38200000

Description

Antifreeze RJK is a fully concentrated coolant and heat transfer agent based on ethylene glycol for summer and winter operation with frost and rust protection effect (year‑round use). Antifreeze RJK is a premium coolant that uses modern P‑OAT (Phosphated Organic Additive Technology) to provide ideal protection for the cooling system. Antifreeze RJK does not contain harmful additives such as nitrites, borates and amines. This coolant is free of silicates, which eliminates any potential problem caused by unstable silicate gel or silicate precipitation. Antifreeze RJK is an all‑round coolant that exceeds industrial standards JIS K2234‑2018, ASTM D 3306 and ASTM D 6210 and can be used in Japanese and Korean vehicles.

Use

Antifreeze RJK 40 can be used without restriction in engines made of cast iron, aluminum and/or a combination of both metals and in cooling systems made of aluminum or copper alloys.
Typical mixtures in Northern Europe contain 50% Antifreeze RJK 40 and 50% water, achieving frost protection down to ‑36°C.
Reliable corrosion protection is achieved with 30% Antifreeze RJK 40 and 70% water.
Can be used in hybrid vehicles and battery‑powered electric vehicles provided there are no requirements for electrical conductivity.
Manufacturer instructions must always be observed.

Miscibility

Antifreeze RJK is miscible with most ethylene glycol based coolants. For optimum corrosion protection and to prevent sludge formation, the unmixed use of Antifreeze RJK recommended. To prepare mixtures, we recommend using deionized (demineralized) or distilled water.
