In 2021, in order to meet customers' needs for promoting the Chinese market, DUREFA will enter the Chinese market, mainly serving corporate customers such as motorcycles and automobiles, and providing high-end car maintenance system products to the market.

1. Coolant for automobiles:

Product Usage:

This product is suitable for the cooling system of gasoline and diesel engines, and has better anti-freeze, anti-boiling and anti-corrosion effects.

Product Features:

Using short chain molecule (SCM) + organic acid (OAT) addition technology, the product has excellent heating and cooling effects, as well as excellent anti-corrosion protection function and excellent compatibility, meeting the needs of motorcycle racing, automobiles, ships, etc. Requirements for use under extreme conditions.

lUnder normal pressure, the product can reach excellent performance of -51℃~140℃ (±5℃), which is different from products with pressure/boiling range protection.

l Does not contain nitrite, effectively prevents corrosion, cavitation, and scaling.

The product's unique formula technology can be used throughout the life cycle of the engine or vehicle.

No corrosion and no evaporation, effectively extending the life of the cooling system and engine.

There is no generation of scale, gel and other sediments, fast cold start, good heat dissipation at high temperatures, and good compatibility with rubber and metal parts.

Main ingredients: biosynthetic alcohol mixture, Freecor@FGB, OAT organic additives, etc.

Implementation standards:

GB 29743.1-2022

Meet certification:

ASTM D 3306/BS 6580/JIS K2234/VW TL 774 G

2. Car GPF maintenance kit:

The GPF disassembly-free cleaning and restoration kit adopts a high-tech environmentally friendly formula. The product is mainly composed of polar molecular activators, alcohol amines, carbon removal agents, dispersants, etc. Through the action of bipolar molecules and additives, one end of the polar molecule is dissolved in water or water vapor, and the other end is integrated with water or water vapor through penetration, peeling, and complexation of complex substances such as carbon deposits, sulfur, and phosphorus. Achieve thorough cleaning of GPF. At the same time, when used with a deep reducing agent, it can effectively deal with the damage to the GPF body caused by toxic and harmful particles such as polycyclic aromatic hydrocarbons, metal salts, and sulfides, and extend the service life of the GPF. This product can effectively reduce exhaust back pressure, reduce engine exhaust resistance, restore engine power, reduce fuel consumption, and reduce exhaust emissions.

Features:

Safety: Polar molecules are cleaned, causing zero damage to the particle trap

No disassembly: No need to dismantle the particle trap

Efficient: 40 minutes of efficient cleaning, no need for high-speed regeneration

Thoroughly: Effectively remove soot particles, SOF, ash, sulfide and other toxic and harmful substances

Instructions:

Please have this product applied by professionals (see the inner bottle for specific usage instructions)

Maintenance suggestions:

1. According to the different GPF calibration of each model, it is recommended to clean and maintain it every 5,000-10,000 kilometers.

2. Under harsh working conditions, such as cold areas, congestion, frequent short-distance driving, and no high-speed driving conditions, please shorten the maintenance cycle appropriately.
