By Mattel recalls this year, China's paint industry jittery. Meanwhile, according to reliable sources, the EU will be in 2008, the content of polycyclic aromatic hydrocarbons in the paint strictly limited. Faced with such a situation, as to rely on manufacturing exports support the industrial coatings industry, the future is how to deal with it?, eyeing a water-based paint, it should be said is the spring of the water-based paint has come.
       The development of water-based paint must be the trend of the future, which is the consensus of many paint companies, whether they have met the requirements only as a supporting aqueous coating raw materials? Whether all high-priced imported goods? Believe many design engineers coating formulations concern problems.
      As important pigment for industrial paint --- aluminum paste, made of water-based aluminum paste whether the target it? Believe tried to engineer domestic waterborne aluminum paste will shake his head here solemnly to report, Dongguan Yamada through long-term technology research, has finally launched a very advanced silica coated aqueous aluminum paste, by detecting the technical indicators have reached the level of similar imported products.
      Aqueous aluminum paste and coated with silica coated with silica aqueous aluminum paste different? Other domestic manufacturers of aqueous aluminum paste is coated?
       : Silica-coated is a chemical coating method, a combination of silica and aluminum is very close, it does not reduce the gloss of the aluminum sheet surface, while the ability of anti-acid is very prominent.
      II: silica-coated aluminum flakes in the paint production, not shearing force due to processing fray cladding layer, the bending effect.
      : Silica-coated aluminum flakes another package at the surface with a layer of resin, both good dispersion, while the binding with the system is also more reliable, to eliminate off silver phenomenon.
      We understand ECKART ILHydrolan series is the this cladding way.
      The products produced in this way, the appearance is relatively dry and fluffy, and certainly not wet the whirring of the together like mud regiment, feeling.
      Domestic waterborne aluminum paste production technology, mostly stearic acid adsorption coated technology abroad as early as this way to be eliminated, its shortcomings are as follows:
      1: This is a physical cladding, coating does not close. Cladding layer is lost easily due to the shearing force in the coating during processing, a differential bending ability.
      : Anti-acid and alkali capacity, especially higher PH value (8.5 - 9) is easy to burn out the aluminum, the aluminum pigment black.
      : Storage stability is poor, and this product production of paint, in the prolonged storage, water or an alkaline substance is easy to penetrate the covering layer, so that the aluminum powder metamorphic, coatings to produce large amounts of gas to produce "up listening" phenomenon.
        Another coating technology, called "passivation" technology, the disadvantage of this coating technology: products containing chromium ingredients. "Chrome" is a heavy metal substances containing hexavalent chromium "in Europe people with them is absolutely prohibited. do not mind at ease. passivation coated aluminum surface of the metal sense a serious decline in thicker aluminum, amounted to less than the requirements of high-grade industrial coatings.
        ECKART HYdrolux series is produced. "Passivation" technology-coated love card product brochures you carefully reference the products containing the words "Cr".
Ten years, domestic production of aluminum pigment and technology are advancing by leaps and bounds, and today, in the process of water-based paint, we Yamada China can contribute to a our honor, our pride.
        Technology in the use of water-based aluminum pigments, we are very happy to discuss with you the progress of our water-based coatings industry!!
