Research Overview

The printed circuit boards (PCBs) used in electronic components are prone to the adverse effects of external environments, which may lead to short circuits or overall system failure. Rising concerns among electrical manufacturers to protect the board and its components from moisture, chemicals, salt spray, and temperature fluctuations are driving the adoption of conformal coatings technology.

Electronics miniaturization has led to complex circuit design, which necessitates the demand for ultra-thin insulating conformal coatings to allow reductions in PCB conductor spacing. The need for coatings technology with complete cures in short periods is a priority in terms of supporting rapid production output with a low margin of defects. At present, solvent-based polymer conformal coatings technology dominates the market; however, it is limited with respect to chemical and electrical performance in challenging operating conditions. Stringent emission norms are encouraging the elimination of solvents with high volatile organic compounds (VOCs), and the industry is shifting to UV/LED curing technology and the implementation of cost-effective automated systems. Innovation in material technology, including composites, nano, and bio-based materials, and the integration of cutting-edge application systems and advanced curing systems will create new growth opportunities for industry participants.
