The curing agent is provided with a filter device, high pressure safety protection device in the pipe line, to ensure the operating more safety .The system is a closed system, put an end to the air and avoid curing agent contacting with the air and curing, to ensure that the media flow stability.

The high pressure valve of base material pump, curing agent pump and proportional pump adopt zero leakage of special alloy grinding, has a unique and convenient adjustable proportioning mechanism, ensure the bi-component sealant almost harsh ratio requirements

The mixing system used precision stainless steel mixer, mixing mandrel, with the specially designed unidirectional needle valve, to ensure the mixing evenly .
