Urethane Conformal Coating

Description

In today’s electronics industry, the need for high level protection of printed circuit boards has become increasingly important. Conformal coating systems provide reliable shielding in harsh environments such as high humidity, dusty, salty, and other corrosive conditions. They offer excellent chemical resistance and safeguard assemblies from moisture and contamination, ensuring long term performance and durability.

Urethane coatings are easy to apply and integrate seamlessly into automated production processes. Their formulations are compatible with common application methods including spraying, dipping, and brushing, offering flexibility for different manufacturing setups. HumiSeal® products are available in 1 , 5 , and 20 liter pails, ensuring suitable options for both small scale and large scale operations.

To support optimal application performance, HumiSeal® offers a comprehensive range of pre‑blended thinners tailored to different coating types and processing requirements. These thinners help adjust viscosity, improve flow, and ensure consistent coating quality across various environments and equipment setups. Most of the pre blended products are available in 5 liter, with some also offered in 20 liter pails.
