The 3YO TS liquid creates a non-stick coating for combs. It protects combs from sparks and corrosion, keeping the fixing holes clean and functional. This reduces costs because the combs do not need to be cleaned and replaced as often. The liquid is 100% natural and biodegradable. Application depends on number of shifts the machine operates: Every 5 working days for 3 shifts Every 10 working days for 2 shifts Every 15 working days for 1 shift
