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.

 Stable to 515

°F (268°C)

 Compatible with rosin, water soluble

fluxes and cleaning solvents

 Leaves no residue
 Dries tack free in 30 minutes
 Non-contaminating



TYPICAL APPLICATIONS
Chemask

protects:

 Component Free Areas for Soldering
 Components
 Pin Connectors During Soldering
 Temperature Sensitive Components

During Wave Soldering

 Sockets
 Board Areas From Conformal Coating
