Product introduction
Water-based Teflon non-stick coating features PTFE as the core component, offering excellent high-temperature resistance up to 260°C. With low friction coefficient ensuring superior non-stick performance and outstanding corrosion resistance against various chemicals, it is specifically designed for aluminum cookware such as woks and frying pans. This coating provides smooth food release during cooking and complies with food contact safety standards.

Instructions
Requirement on pre-treatment
· Firstly, degreasing at high-temperature, then wash with 1%~3% NaOH solution (60℃) for more than 6
minutes, dry it after water rinsing;
· Blast with 80#~120# corundum to make the surface roughness reach 2.0 μ ~3.0μ, pay attention to
sandblast evenly;
· Wash with 1%~3% NaOH solution(60℃) for more than 6 minutes, rinse with water;
· Wash with 1%~3% hydrochloric acid solution (60℃) for more than 6 minutes, rinse with water and dry.
Preparation of the coating
· The
primer mid coating and top coating must be fully dispersed before
operation. Rolling the coating at the speed of 30rpm with rolling machine for 30min. Checking
the bottom of bucket without precipitate, agglomeration. Be careful not to exceed 60min;
· Coating filtration: filtrate the coating with screen (150mesh) before using.(Except the topcoat).
Application
The spraying environment should be dry, well-ventilated, without dirt, recommend using dedicated
spray gun, elevated tank and curing oven;
· The air compressor should be degreased, dewatered and equipped with water oil separator
before using;
· Adjust atomization and oil pump capacity of the spraying gun; make sure the unit is clean and flat;
· Make the pretreated substrates clean before spraying;The pan spraying primer, primer coat could be sprayed
with normal spray gun; then increase the temperature to 180℃ gradually and keep for 10min, after
cooling， top coat should be uniform, then increase the temperature to 380℃ gradually and keep for
8min ~10min; control the dry film thickness of the primer and top coat in the range of 22μm~30μm.
The oven (or the tunnel drier) must be well ventilated, with good conditions to meet requirements of
temperature: about 10 minutes for temperature increasing, enough curing time; otherwise, it will lead
to color change of coating.
