START International® PC101™ is a single-Component, fast-drying, easily-repairable coating for printed circuit boards and electrical equipment. PC101™ is a clear compound of specially polymerized resins that protects circuit boards and electronic components from the atmosphere. It dries tack-free at room temperature within ten minutes of application and cures to a tough, flexible covering. PC101 ™ has widespread acceptance in the electronics industry, is used by many major production companies and corporations, and was developed to meet mil spec MIL-I-46058C.

Features:

• Has high resistance to chemical vapors, is completely waterproof and is unaffected by both salt and fresh water
• Provides permanent protection against corrosion, mildew, and electrolysis on all non-ferrous metals used in the electronics industry
• Durable enough to withstand continuous operating temperatures between -60ºF (-51ºC) and 280ºF (138ºC)
• Can be applied by brush, spray, dip, or curtain coating
• Solderability of parts is maintained with the use of PC101 ™
• Resistant to discoloration, even at high temperatures
• Can be thinned for spraying
