Chemtronics Chemask® Peelable CM8 - Manual

PRODUCT DESCRIPTION
Chemask

is a fast curing peelable solder
masking agent. It contains a high
temperature resistant compound that protects
component-free areas during wave soldering.
Chemask

may be used to protect pins,
posts, contacts and edge connections during
conformal coating processes.
