Product introduction
Tebang nano non-stick coating is colorless and transparent. It is easy to apply, requiring no substrate sandblasting. After simple spraying and baking, a nano film forms on the substrate surface, giving it extremely low surface energy, superhydrophobic/superoleophilic, or ultra-smooth properties, achieving 'oil and water repellency, and resistance to dirt adhesion.' The nanoscale structure also provides the coating with multiple advantages, including self-cleaning, wear resistance, and corrosion resistance.

Instructions
Requirement on pre-treatment
· Before sandblasting, the surface of the substrate needs to be degreased and cleaned at high temperatures.
. We recommend that the particle size of the sand grains be between 90-120#, and please control the speed and angle of the spray when spraying. A suitable roughness (recommended between Ra2.0μ-3.0μ) can provide more mechanical occlusion points, which is beneficial for improving the adhesion of Teflon coatings.
. Then clean water to wash away dust and residual sand, and finally dry and inspect to ensure that the surface is free of oil, moisture, rust or other dirt.
Preparation of the coating
. Before the primer and face oil are used, the paint must be fully dispersed, and the bottom must be checked by rotating at a speed of 30rpm for 30min on the barrel roller
There is no precipitation and agglomeration, and the bottom oil can be used only after it is evenly dispersed, and the rolling time should not be greater than 60 min.
. The paint is filtered with a 150 mesh filter.
Application
Adjust the atomization and oil output of the spray gun before spraying, and ensure that the spraying workpiece is clean and smooth;
Single-layer spraying
. Clean the pre-treated substrate and then spray; After spraying, slowly raise the temperature to 280°C, keep it warm for 10 minutes, and then cool it to room temperature after 10 minutes.Two-layer spraying（For a higher gloss effect, you can choose it）
. One layer of spraying is carried out first, and after completion, it is baked at a low temperature of 60-100°C, and after cooling, a second layer of spraying is carried out, the temperature is slowly raised to 280°C, and it is cooled after holding for 10 minutes;
