Chemask HV - High Viscosity Peelable Solder Mask
Chemask HV Solder Masking Agent is a temporary, high viscosity, fast curing, peelable solder masking agent. It is a high-temperature resistant compound that protects component-free areas during wave soldering. Chemask HV can be introduced to the wave solder preheat within 4 minutes without adverse effects. Chemask HV may be used to protect pins, posts, contacts and edge connections during conformal coating processes.
Chemask HV Solder Masking Agent is engineered for all electronic manufacturing applications. When applying by hand using squeeze bottle, syringe or spatula, ensure 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. 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.
Key Features:
- Usable within five minutes of application with preheat cycle
- More controlled application
- Thicker coating does not seep through thru-holes
- Latex material is compatible with flux systems and stable with cleaning solvents
Typical Applications:
- Increase manufacturing speed with preheat cure cycle
- Ideal for all thru-hole manufacturing applications
- Use as a protective mask during conformal coating process for: switches, pins, posts, contact and edge connections
