  • Publication number: 20100261031
    Abstract: The present invention relates to the manufacturing method of metal clad laminates by forming a conductive layer on a single side or both sides of a material film that is made of an insulating material using the silver complexes having a unique structure and electroplating metals outside of said conductive layer. The present invention can provide the manufacturing method of metal clad laminates, which has a fast operation speed for mass production, simple process steps to minimize defective ratio and cheap production cost.

  • Publication number: 20090269595
    Abstract: The present invention relates to an aluminum wheel having high gloss and a method for manufacturing the same, and the method for manufacturing an aluminum wheel having high gloss includes the steps of: (i) coating a primary coating powder paints for increasing a flatness of an aluminum wheel having a rough surface and improving an adhesive force to a silver mirror coating surface, (ii) forming of silver coating layer forming a mirror surface having a high gloss and high reflectivity on the powder paints coated surface using a silver coating solution, and (iii) forming at least one transparent top coating for protecting the silver mirror surface and increasing an abrasion resistance and a saltwater resistance after the step (ii). In accordance with the present invention, an aluminum wheel having high gloss and high reflectivity can be manufactured in a simple processes and relative inexpensive cost.

  • Publication number: 20090220696
    Abstract: The present invention relates to compositions for forming reflecting layer having organic silver complexes, and method for preparing reflecting layer using the same. More specifically, it relates to compositions for forming reflecting layer including silver complexes that have distinct structures and the method for preparing reflecting layer, where primary coating is applied to promote the adhesive force to materials such as plastic, ceramic, metal, etc. and then a high-reflecting layer is formed by using the silver coating fluid, followed by transparent coating for protection.
