pasta de aluminio is a pigment. It is processed through special processing technology and surface treatment to make the surface of aluminum sheet smooth and flat, with neat edges, regular shape, concentrated particle size distribution, and excellent matching with the coating system. Aluminum paste can be divided into two categories: floating type and non-floating type. During the grinding process, one fatty acid is replaced by another, which makes aluminum paste have completely different characteristics and appearance. The shapes of aluminum sheets are snowflake-shaped, fish scale-shaped and silver dollar-shaped. Next, this article will briefly introduce whether aluminum paste is a hazardous product and what are the precautions for storing aluminum paste. Let's take a look at it together!
1.Is aluminum paste a hazardous product?
Is aluminum paste a hazardous product? I believe this question is of great concern to many customers who need to use aluminum paste, especially under the premise of increasing water-based and safe production requirements at this stage.
Aluminum paste is not easy to catch fire and explode. Hiding power, brightness, triggering performance, metal properties, and smoothness are the technical requirements for identifying aluminum paste. The aluminum paste model is classified according to the size of the particle size. Uses: Widely used in plastic paint, hardware and home appliance paint, motorcycle paint, bicycle paint, etc. According to the list of hazardous chemicals, aluminum paste belongs to category 33646: paints, auxiliary materials and coatings containing secondary flammable solvents.
However, due to the international and domestic requirements for environmental protection and safety of chemical products in recent years, domestic manufacturers have changed their processes and no longer use secondary flammable solvents as carriers, but choose safe and environmentally friendly solvents with higher flash points. The aluminum paste produced now is no longer a hazardous product in terms of actual chemical properties.
2.What are the precautions for storing aluminum paste?
Store in a sealed can indoors at a storage temperature of 15-40℃. Avoid direct exposure to sunlight, rain or excessively high temperatures.
Ensure that the storage temperature is not lower than 15℃ (special attention should be paid in winter or when the ambient temperature is equal to or lower than 10℃).
Excessive bumps and vibrations during transportation and storage under certain conditions may cause partial separation of aluminum and solvent components. Therefore, high-speed stirring should be avoided during use to avoid destroying the shape of the silver sheet.
