CHEMTRONICS(R) TDS # CM8E Technical Data Sheet Chemask(R) PRODUCT DESCRIPTION (R) 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(R) may be used to protect pins, posts, contacts and edge connections during conformal coating processes. Stable to 515F (268C) Compatible with rosin, water soluble fluxes and cleaning solvents Leaves no residue Dries tack free in 30 minutes Non-contaminating TYPICAL PRODUCT DATA AND PHYSICAL PROPERTIES Solvent Stability Flux Compatibility Stable in all Hydrocarbons, Hydrofluorocarbons, water and chlorinated solvents All Types Temperature Stability 515F Tack-Free Drying Time (10 mils @ 77F) 15 min. Cure Time (10 mils @ 77F) 30 min. Viscosity (@ 77F) ( 300 cps) Viscosity Adjusted With Flash Point Component Free Areas for Soldering Components Pin Connectors During Soldering Temperature Sensitive Components During Wave Soldering Sockets Board Areas From Conformal Coating Pink Color Solids Content TYPICAL APPLICATIONS Chemask(R) protects: Natural latex rubber Base Material Weight/Gallon Shelflife 18,000 cps DI Water ~ 60% Nonflammable 7.2 lbs. 2 year RoHS/WEEE Status COMPATIBILITY Chemask(R) is generally compatible with most materials used in printed circuit board fabrication. As with any solder masking agent, compatibility with substrate must be determined on a non-critical area prior to use. APPLICATION METHOD Squeeze Bottle/Syringe Spatula Screening Automatic Dispensing Removal/Clean-up Yes Yes No Yes By Hand USAGE INSTRUCTIONS For industrial use only. Read MSDS carefully prior to use. Chemask(R) solder masking agent is engineered for all electronic manufacturing applications. When applying by hand using squeeze bottle or spatula, insure that all areas of the pretinned hole are evenly covered on the side to be soldered. Automatic dispensing equipment may also be used as appropriate. REMOVAL: After allowing the mask to become fully cured, peelable solder mask can be removed by hand or by the use of tweezers. Depending on ambient conditions, peelable mask may remain on assemblies for extended periods of time prior to component insertion. AVAILABILITY CM8E 200 ml. Squeeze Bottle CM1 3.7 L.
