CHEMTRONICS TDS CM8E Technical Data Sheet Chemask TYPICAL PRODUCT DATA AND PHYSICAL PROPERTIES PRODUCT DESCRIPTION Natural latex rubber Base Material Chemask is a fast curing peelable solder Color Pink masking agent. It contains a high Solvent Stability Stable in all Hydrocarbons, temperature resistant compound that protects Hydrofluorocarbons, water component-free areas during wave soldering. and chlorinated solvents Chemask may be used to protect pins, posts, Flux Compatibility All Types contacts and edge connections during Temperature Stability 515F conformal coating processes. Tack-Free Drying Time 15 min. (10 mils 77 F) Stable to 515 F (268 C) Cure Time Compatible with rosin, water soluble 30 min. (10 mils 77 F) fluxes and cleaning solvents Viscosity ( 77 F) Leaves no residue 18,000 cps ( 300 cps) Dries tack free in 30 minutes DI Water Viscosity Adjusted With Non-contaminating Solids Content ~ 60% Flash Point Nonflammable TYPICAL APPLICATIONS Weight/Gallon 7.2 lbs. Chemask protects: Shelflife 2 year RoHS/WEEE Component Free Areas for Soldering Status Components Pin Connectors During Soldering Temperature Sensitive Components COMPATIBILITY During Wave Soldering Chemask is generally compatible with most Sockets materials used in printed circuit board Board Areas From Conformal Coating fabrication. As with any solder masking agent, compatibility with substrate must be determined on a non-critical area prior to use.
