Name:Asphalt K3, K4
Model: BC-K3/BC-K4 Asphalt
Description: BC-K3/BC-K4 asphalt is a black lump asphalt, which is mainly used in the upper plate, polishing and protective film of optical lens processing.
Advantages: It can completely replace the K3/K4 asphalt of Japan's Kouzhong Electric.
Precautions for use:
1. When using the upper plate, please pay attention to the processing and heating temperature, long-term high temperature will damage the quality (recommended below 230 ℃)
2. According to the type of polishing machine and the size/shape/material of the parts, the polishing conditions are not necessarily. In principle, the operating room temperature is better at 19-25℃, and the temperature of the polishing liquid is better if the temperature can be maintained at a constant temperature.
3. If it is used as a protective film, it can be sprayed with environmentally friendly liquid, toluene, and cured at a constant temperature of about 70 degrees for 150 seconds (it can be irradiated with a strong light)
4. Organic cleaning agents such as white mineral oil can be used for cleaning
