Description

CPU-A is manufactured as per our proprietary formula, specialized process and facility. This product is not categorized as regulated chemical, featured as an environment-friendly and safe product,easy to use, transport and store. It can be used as a substitute for lithium based thickener, it has high cost performance ratio. Customization is available upon request

Use instructions

The product is hygroscopic, it is suggested to be sealed while storing.The product tends to form lumps after long term storage, but it does not affect application, but the lump should be smashed before use.The product contains some small particulate, which is easy to float, keep the workplace ventilated and pay attention to operators' safety to prevent human inhale and dust-explosion duet to the dust accumulation.For more details, please refer to the SDS.

Direction for use of CPU-A

1、2/3 of total oil is fed into kettle, heated to 70±5℃（degree Celsius）, add metered thickener powder, then heated to 120℃（degree Celsius） gradually, slowly add the remaining base oil and keep heating it up.

2、Once the temperature reaches 130±2℃（degree Celsius）,hold for 60 minutes.

3、Add Additives when temperature drops to 110℃（degree Celsius）, blending and recycling for 30 minutes, use three roll mill or high pressure homogenizer to treat the grease, high pressure homogenizer pressure is recommended at no less than 40 MPa.
