ZF428-LT is an aqueous, double layer (or triple layer) and anti-adhesive coating and is made from PTFE and polyamide-imide. It is anti-adhesive, smooth, abrasion-resisting and anti-corrosive, so it is especially used in cooking utensils. It has 7 features:
1. No PFOA
2. Longer time of non-adhesion. According to protein peeling test, its peel strength has been reduced by 50%
3. Strong abrasion resistance. More than 5000 laps/mil in Taber abrasion test (500g/CS-10 grinding wheel/60 revolutions per minute)
4. Strong non-corrodibility. Endure 50 hours of 10% salt water boiling test (refer to light industrial standard QB/T2421-98)
5. Comply with food laws and regulations in other countries (ROHS, FDA, SVHC, LFGB, etc.)
6. No specific requirements for coating equipment. Existing air spraying production line suffices
7. Normal superficial treatment on parent metal (aluminum needs sandblasting or chemical erosion, stainless steel must be sandblasted)
