Benefit of our solutions
• Coating is wide range application in any rotating machine I.e. screw conveyor, blower etc.
• Improve reliability and service life for existing machine and can apply to new equipment also.
• Minimize repairing time.• Reasonable cost and lower cost when comparing to
upgrade equipment material.• Smooth surface so easy to clean, inspect and repair.• Many application for chemical resistance and abrasion.• Able to service in high pressure and high temperature
condition.
