Henkel Launches Toluene-Free Conformal Coating
Conformal coating compound.
Irvine, CA — Henkel has launched a new quick drying, toluene-free conformal coating system, Hysol® PC62. Based on the company's popular Hysol PC52 platform, the new formulation is a one-component solvent-based acrylic conformal coating that provides environmental and mechanical protection for PC boards. Designed as a toluene-free alternative, the product delivers the obvious benefits of a non-toluene material.

Yet, the material has all of the quick drying advantages of a traditional toluene-based system. In testing against other toluene-free materials, Hysol PC62 delivered drying times as much as four times faster than the closest competitor.

With increasing pressure to eliminate toluene-based conformal coatings, there have been numerous attempts to develop alternative systems. According to the company, while there are some other toluene-free options on the market, many of these materials do not deliver the performance advantages required for today's manufacturing conditions.

Though the electronics industry is slowly shifting away from solvent-based conformal coating systems, the migration will likely be quite gradual as solvent-free, or even water based, materials simply do not offer the ease of use or performance capabilities of solvent-based systems. Hysol PC62 has been specifically engineered for those electronics manufacturers that cannot move to current solvent-free systems but want to eliminate toluene from their manufacturing operations.

Designed for high reliability, the new formulation is especially suited for any environment where a printed circuit board will be subjected to harsh conditions, particularly automotive, military, aerospace, industrial and consumer avionics applications. Like Hysol PC52, Hysol PC62 is compliant with UL746 and IPC-CC-830 requirements and is especially suited to application with non-atomized selective spray coating equipment.
