Which segment leads?

Acrylic-based conformal coatings represent an important product category because they provide protective properties while offering relatively straightforward application and rework characteristics. Acrylic coatings can be used in applications requiring protection from moisture, dust, and environmental contaminants. Other coating chemistries, including silicone, polyurethane, epoxy, and parylene, address different requirements related to flexibility, chemical resistance, thermal stability, and environmental protection.

Silicone-based coatings can provide flexibility and performance across broad temperature ranges, making them relevant for automotive applications exposed to thermal cycling. Polyurethane coatings can provide strong resistance to moisture and chemicals, while epoxy formulations can offer durable protection for demanding applications. Parylene coatings provide thin, conformal protection and can be applied to complex component geometries.

Printed circuit boards, electronic control units, sensors, lighting systems, power electronics, and other automotive electronic assemblies represent important application areas. As vehicle electronics become increasingly compact and integrated, coating technologies must provide consistent coverage without interfering with electrical connections or component functionality.
