HP-618 Phosphorus-free pre-filming agent
The HP-618 phosphorus-free pre-filming agent, used in conjunction with phosphorus-free cleaning solutions, is applied in places with strict environmental protection requirements. It is an environmentally friendly solution that can directly transit to cold operation after pre-filming with small amount of water changes. This plan is applicable to open circulating cooling water systems, water supply pipelines, central air conditioning systems, etc. The HP-618 series products are mainly compounded with polycarboxylic acids, high-efficiency corrosion inhibitors, etc. In combination with corrosion inhibitors for non-ferrous metals, they can effectively form films to prevent corrosion of various metals.
