What is metallic paint?

1. Introduction

not only allows the sheet surface after the coating sparkling look more attractive, but also at various angles due to the refraction of light, make the car color, even profile will change. So that the vehicle exterior styling looks richer and more interesting, which is why “metallic paint” will be one of the increasingly common truth.
metallic paint, metallic paint known; is a prevailing automotive topcoats. Group in its paint fine aluminum particles added, after the light incident on the aluminum particles, and aluminum particles is reflected gas permeable membrane. Therefore, it looks like the same metallic glitter. This metallic paint, give people a pleasant, light, new feeling, so now widespread. Changing the shape and size of the aluminum particles, you can control the flash of the metal film of the flash; metallic paint outside, and also supplied with a varnish layer to protect.
metallic powder is a metal, such as copper, aluminum or the like as a high-grade pigment architectural coatings formulated. Metallic glitter having metallic texture, grade buildings can be improved, and demonstrates the noble, elegance. There are generally two kinds of water and solvent based. Since the metal powder is unstable in air and water, a chemical reaction often occurs deterioration, and therefore require special handling surface thereof, so that the price for the metal powder in the water-based paint is expensive, the use is restricted, is still mainly based solvent .

2, the difference between the common paint and metallic paint

In addition to high hardness metallic paint, but also the performance level of the vehicle body beauty. Cause “metallic paint” more and more popular is another reason it is mixed with a metal powder, with the metal components, thus increasing the hardness of paint, paint hardens, it is less likely to be scratched.

there are some “prime paint” is not metallic paint, several of the most typical color is white, black, red, and yellow; not to say that these colors can not add silver paint, but after the addition of silver powder, the apparent color is not original Stern, will become white pearl white, black with bright light will become “carbon black”, will become the so-called redThe “burgundy”, while yellow will become catching people’s “golden.”
without addition of a metal powder pigment paints, paint hardness will be relatively soft, not only high-speed driving road surface by flying stones hit the bounce, easy peeling paint. Further, car paint pigment during cleaning must not directly damp cloth or dry cloth, the absolute use a lot of water to wash away the dust adhering to the surface of the paint, so as not to contact with the vehicle body when a rag, will let the hard gray sand have the opportunity to scratch the paint.

3, metallic paint composition

by a fluorine resin, quality pigments, additives, curing agent composition is a two component room temperature curing coating.

4, metallic paint properties

film tough, strong adhesion, UV has a strong corrosion resistance, high fullness, can improve the service life of the coating and from – cleaning.

5, metallic paint application

applied to metal, wood, plastic, protective overcoat external walls of buildings, it can also be made of epoxy, urethane, acrylic series paint decorative protective overcoat .

6, technical parameters

metallic paint film hardness index detection method ≥3h GB / T6739-1996 Adhesion (circle method) Level 1 GB1720-79 (89) Impact Strength50cm GB / T1732-93 flexibility 1mm GB / T1731-93 freeze-thaw resistance film 20 does not blister, do not fall off, crack-free water resistance GB9154-88 (room temperature) 200 hours, the film does not blistering, no loss GB / T1733-93 -40deg temperature; C – 140deg; C using normal GB1735-79 resistance to artificial aging 5000 hours no powder, no loss, no cracks GB1865-80 (89)

7, metal paint construction method

1. the metallic paint can be rolling, spraying, brushing process and the like, according to the uniform mixing ratio, as the case when the spray metallic paint was diluted with thinner.
2. applicable to all types of cement plastering mortar, concrete surface, gypsum board, wood, fiber board.
3. The base surface must be firm, dry, clean and free from dust, PHlt; 10.

8, Note

1, metallic paint brush before carefully clean the surface to be coated, in addition to oil, the old wall with a suitable wire brush cleaner and degreaser or other tool remove the old paint is not strong, sand. Available leveling wall repair putty, wall confirm dried thoroughly clean, reliable, smooth, moisture content less than 8 percentage.
2 was sufficiently stirred before use A first component is uniformly Press A / B = 100: 15 formulation (weight ratio) ratio, aging stir 20min, can be brush, spray and the like; Coating intervals 6-8h (25deg; C).
3, tank life: 6h (25deg; C,Reduced with increasing temperature).
4, temperature requirements in the construction 0deg; more C, 40deg; C or less, and above the dew point 3deg; C, the relative humidity may not exceed 85 percentage.
5, diluent: Fluorocarbon thinner metal, cleaning tools available benzene solvent.

Cleaning

To maintain a clean appearance metallic paint, dust wipe alone is not enough to pay attention to timely and regularly cleaned vehicle. Waxing

To maintain the appearance of metallic paint, wax is indispensable. But frequent waxing, waxing and simply do not superstition imported wax, are in fact inappropriate. Due to the different properties of various wax, its role and effect are not the same, so you must be careful in the selection. Inappropriate choice not only can not protect the body, but will make the paint color. Under normal circumstances, should be considered based on the role of wax, characteristics, recency vehicles, paint color and vehicles traveling environment and other factors. Patch

professional repair scratches have strict requirements on the operating environment, as is the effect of dust and paint fear impurities. If dust, fibers on the worker’s operation of dandruff or clothes fall on the outer surface of the vehicle body, will form a spot or a bulge. Maintenance

The outer spray paint plastic parts, use high quality detergent for cleaning; waxing not too forceful to prevent the penetration of paint is exposed background.
