Master Sil 773 is a rapid cure to tack-free, ready-to-use silicone conformal coating for printed circuit boards. It protects electronic circuitry in high humidity environments as well as upon exposure to shock and vibration. It cures quickly at ambient temperatures to a flexible, transparent, low hardness silicone coating. It delivers strong adhesion to critical board components. It maintains its low modulus over a wide temperature range of -85Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â° F to more than 390Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â° F. It is 100% reactive and cures by moisture. If needed, a UV tracer dye is also available with this system.
It can be applied by dipping, spraying, or brushing. It is suitable for either manual or automated coating techniques as its tack free time is less than 5 minutes.
