The function and painting skill of stainless steel anti fingerprint oil
The composition of stainless steel anti-fingerprint oil: the use of water-based modified butyl acid resin high-performance baking coating, in line with international coating safety regulations and EU Rohs testing specifications, new environmentally friendly coating materials, does not contain any toxic substances, no environment and human body Any toxic side effects.
The role of environmentally friendly stainless steel anti-fingerprint oil:
1. Excellent acid and alkali resistance, weather resistance and corrosion resistance. Simply put, anti-fingerprint oil is applied on the metal surface to extend the service life of the metal.
2, excellent anti-fouling (especially in the appearance of bright stainless steel products, as long as the fingerprint left by the finger is difficult to organize, the sweat on the hand may be contaminated with oil will cause corrosion of stainless steel products, coating anti- Fingerprint oil handles finger prints easily and is easy to clean).
3, excellent flexibility and good hardness, strong adhesion (refers to anti-fingerprint oil coating after high temperature curing on the metal substrate adhesion is very good, not easy to fall off, high hardness means that the coating is resistant to scratch , not easy to paint off).
Tips for stainless steel anti-fingerprint oil coating:
1. It is necessary to remove oil, dust and other substances on the surface of the substrate to ensure the appearance and enhance the adhesion of the coating to the substrate. (If the surface of the substrate is oily, the coated coating will be scattered. If there is water stain on the substrate, the product coated with anti-fingerprint oil will leave a watermark after baking, so the substrate is cleaned. It is necessary to do well)
2, the choice of painting things: advocate the use of water-based electrostatic spray gun, its atomization is the best (such as the use of manual spray gun, advocate the use of 1.0 caliber below, the spray is adjusted to the best atomization situation. The spray distance is best controlled at 20cm- Between -40cm, the amount of the conditioning nut is tightened and screwed out for about one and a half times. The air pressure is adjusted to meet the requirement of dispersing the mist to a fine and uniform. The solvent is too large to evaporate much without touching the substrate. Dry spray, too small atomization is not good, like small raindrops are uneven. The spray gun should be perpendicular to the outer surface of the substrate for parallel movement. The surface of the substrate is covered with atomized particles and then moved to the spray gun instead of seeing the brightness and then moving. Br />
3, before use, it is necessary to mix well and prevent the sedimentation leading to the color difference and appearance of the film (especially the color of the color is fine, the mixture must be evenly mixed, there is no uniform mixing, simple color difference, uneven color, etc.)
4, water-based anti-fingerprint oil series of paints contain anti-fouling substances, no need to spray too thick, too thick coating can not be re-coated.
5. The share of water (depending on the different production environment and products, the water share should not exceed 30%, and the test is added in batches. Too much water will affect the functions of the coating)
6. After painting, it is necessary to stand in a dust-free environment for 5~10 minutes and then gradually bake (because the water-based anti-fingerprint oil is diluted directly with water, all the water is evaporated, and the evaporation of water is slow. If there is direct entry into the high temperature baking, bubbles will appear)
7. It is necessary to bake at 140~200°C/30min when baking. If the baking time is insufficient, the hardness of the coating film will not work, and the functions of water resistance, moisture resistance, gasoline resistance and alcohol resistance will be reduced; When it is excessive, the gloss is lowered, and the appearance of low-yielding such as yellowing occurs together, and physical functions such as impact resistance are lowered.
