Aluminum paste is a widely used metallic pigment with a silver-grey metallic luster. It is commonly known as silver paste in the coatings industry. It is actually metallic aluminum paste and does not contain any silver components. It only has a silver metallic texture.It is a type of pigment paste that contains aluminum flakes or powders suspended in a solvent. It is primarily used in various industries for its unique properties and applications. Here are some applications of aluminium paste: Ⅰ.Painting & Coatings Ⅱ.Automotive Industry Ⅲ.Printing Inks Ⅳ.Reflective Films Ⅴ.Construction Materials Ⅵ.Electronics and Appliances It's worth noting that the specific applications of aluminium paste can vary depending on the formulation and the requirements of different industries. Additionally, the use of aluminium paste should follow applicable safety guidelines as aluminum can be a flammable material in certain forms.

Waterborne aluminium paste,developed with the growth of Water-based coatings. As the metal aluminum is amphoteric active metal elements, which is easy to react with water, acid and alkali, it should take special surface treatment when add in aqueous resin system. It disperses well in the solvent of water and alcohol with good acid and alkali resistance ability. Currently in the market,the way of making aqueous aluminium paste can be divided into 3 methods: 1.Chromic acid, phosphoric acid, modified resin and salt passivation method; 2.Silica coating method; 3.Inorganic&organic double layer coating or hybrid coating method. Different methods have different advantages and disadvantages and they all occupy a certain share in the market. Along with the progress of society and the requirements for environmental protection and characteristics of product, the last two methods take great advantage in the market

    Brilliance, brightness, colour saturation, coverage, flop and DOl - depend not only on particles and particle size distribution, but also on the orientation of the aluminium flakes in the paint film. Best effects are achieved when the flakes lie parallel to the surface of the film. Poor orientation :leads to"clouding" or to an uneven "salt and pepper" effect. The evaporation of the solvent causes the film t shrink and virtually press the aluminium paste into a horizontal position.     The higher the solvent content of the paint, the more pronounced this effect is. This explains the observed phenomenon that pigment orientation and thus the optical properties of" low solid paints"are considerabl'y better than those of high solid paints".
