Latest Patents

One of Chan's latest patents is focused on a shielding coating for selective metallization. This innovative shielding coating is applied to polymer substrates to facilitate selective metallization. The process involves a primer component and a hydrophobic top coat. Initially, the primer is applied to the polymer substrate, followed by the application of the top coat. The shielding coating is then selectively etched to create an outline of a desired current pattern. A catalyst is subsequently applied to the patterned polymer substrate, leading to electroless metal plating in the etched portions. The areas of the polymer substrate that contain the shielding coating inhibit electroless metal plating. The primers used in this process contain polyamines, while the top coat is composed of hydrophobic alky organic compounds. Another similar patent also emphasizes the use of five-membered heterocyclic nitrogen compounds in the primer, showcasing Chan's innovative approach to enhancing the performance of shielding coatings.
