This product is special designed for cutting crystal with electroplating diamond wire saws and copper-based sintered diamond wire saws, but also for cutting optical glass, ceramics and other hard and brittle materials. It is light brown, transparent water-based liquid, weak alkaline, non-formaldehyde and other toxic substances. According to the requirement, it can be added into water at the ratio of 5% ~ 50% when uses. It has longer serving life, also can improve cutting efficiency, extend working life of workpiece, replace imported anti-rust oil and cutting oil. The unique advantages of the product are higher cutting efficiency, better lubrication, stronger rust-proof ability and faster speed of conduct heat. It is cleaned easily and don’t smear processing surface, also has the effect of deodorization. According to different purposes, it can be chosen different dilution ratios. For example, liqiud with 50% of the concentration ratio has excellent results under the circumstances with strong anti-rust demand, such as cast iron parts. No drinking.
