MK-886 Lubricating Oil Cloud Point Depressant

Product Overview

This product is a highly efficient cloud point depressant specifically developed for lubricating oil systems. It employs advanced high-molecular polymer technology to address issues such as excessive wax crystal precipitation, high cloud point, and oil turbidity caused by low-temperature environments in mineral base oils. By selectively altering the crystallization morphology and structure of wax crystals, it prevents the formation of a network structure through wax crystal aggregation, significantly lowering the cloud point of the lubricating oil system. At the same time, it ensures the oil’s low-temperature cleanliness, fluidity, and operational stability, preventing wax crystal blockages in oil lines and filters, and guaranteeing the continuous lubrication and protective functions of the oil under severe low-temperature conditions.

The product features excellent oil solubility, thermal stability, and compatibility, and can work synergistically with various conventional lubricating oil additives without affecting the oil’s original viscosity, oxidation resistance, and anti-wear properties. It is widely applicable to the formulation of various automotive and industrial lubricating oils and is a dedicated functional additive for enhancing the low-temperature performance of lubricating oils.

Core performance features:

1. Efficient turbidity reduction: Specifically designed for the targeted modification of lubricating oil base oils, it can rapidly lower the cloud point of the system by 8-22°C, completely resolving the issue of oil turbidity at low temperatures and maintaining the clarity and transparency of the oil.
2. Wax crystal control: Precisely inhibits the growth and aggregation of wax crystals, converting large wax crystals into fine, dispersed crystals, preventing clogging of oil lines and filters, and ensuring smooth operation of the lubrication system at low temperatures.
3. Excellent compatibility: Perfectly compatible with detergents, dispersants, antioxidants, anti-wear agents, pour point depressants, and rust inhibitors, among other lubricant additives, without antagonistic reactions and without disrupting the original formulation of the oil.
4. High thermal and chemical stability: Remains stable during high-temperature blending and under operating conditions, does not decompose, cross-link, or deteriorate, and does not generate sediment, thus not affecting the service life and oil change cycle of the lubricant.
5. Low dosage and high cost-effectiveness: Requires a small amount of addition, with significant effects, does not increase the viscosity of the oil, does not alter the basic physical and chemical properties of the oil, and is suitable for large-scale industrial production.
6. Wide application range: Compatible with various paraffinic, naphthenic base oils, and synthetic hydrocarbon base oils, meeting the low-temperature modification requirements of different grades and types of lubricating oils.

Scope of Application

1. Vehicle lubricants: gasoline engine oil, diesel engine oil, gear oil, transmission oil, hydraulic transmission oil, etc. are all vehicle lubricants.
2. Industrial lubricants: industrial gear oil, hydraulic oil, bearing oil, circulation system oil, refrigeration oil, guide rail oil, metal processing lubricant, etc.

Recommended addition amount

Based on the quality fraction of the finished lubricating oil, the recommended addition ratio is 0.5% to 1.5%. The specific amount can be flexibly adjusted according to the wax content of the base oil, the distillation range, and the target cloud point requirements. For low-wax base oils, a lower addition amount can be selected, while for high-wax base oils, the addition amount should be appropriately increased.

Usage instructions

1. Additives during blending stage: When blending the lubricating oil base oil, add this product in the prescribed proportion to the base oil, heat it to 40-60℃, and stir for 30-45 minutes to ensure complete dispersion and dissolution of the product, and then mix it evenly before adding other functional additives.
2. Additives for finished oil: For the finished lubricating oil that has been blended, it can be directly added with this product. Through a circulating pump, stir it for more than 40 minutes until the product is completely dissolved, without stratification or turbidity.
3. Precautions: This product should be added before the oil does not crystallize with wax. If the base oil has already crystallized, it is necessary to first heat it until the wax crystals are completely dissolved before adding it. Do not add it directly to the waxed oil. This product can be used in combination with demulsifiers to further enhance the low-temperature fluidity of the oil. It can be used as a substitute for demulsifiers in some oils.

Storage and Transportation:

During storage, transportation, loading and unloading, the maximum temperature of this product should not exceed 75℃. If stored for a long time, the maximum temperature should not exceed 45℃. Do not allow water to enter. This product is non-flammable, non-explosive and non-corrosive. In terms of safety, environmental protection and usage, it is the same as ordinary petroleum products and no special protection is required.

Packaging:

200-liter steel drums, with a net weight of 180 kilograms per drum; IBC ton drums, with a net weight of 900 kilograms per drum.
