早在六十年代,国外就对水基型的压铸涂料进行了大量的研究,将高性能,无污染的化工产品引入压铸涂料领域,使水基涂料获得迅速发展,先后在许多国家得到广泛应用。普遍认为水基涂料具有脱模性能好,冷却效果强,无污染,铸件表面光洁,能降低铸件气孔率等诸多优点,是较理想的压铸涂料。 As early as the 1960s, a great deal of research was done abroad on water-based die-casting paints. The introduction of high-performance, non-polluting chemical products into the field of die-casting paints led to the rapid development of water-based paints and their widespread application in many countries . It is generally considered that water-based coatings have many advantages, such as good mold release performance, strong cooling effect, no pollution, smooth casting surface, and low porosity of castings, which are ideal die-casting coatings.
