1 To 1 Mix Silicone Encapsulation,
Waterproof Silicone Encapsulation,
Good Flowability Silicone Encapsulants
MC Silicones delivers a wide variety of silicone-based polymers for diverse solutions in electric, electronic and energy application cases. Silicone encapsulants are protective materials used to completely embed electronic circuitry. Typically, they are used to protect circuits from harmful effects of moisture and other contaminants, provide electrical insulation for high voltages and also protect the circuit and interconnections from thermal and mechanical stress.
• Good flowability
• Room temperature or heat accelerated cure
• Moderate thermal conductivity
• UL 94V-0
• Rapid, versatile cure processing controlled by temperature
• Can be considered for uses requiring added flame resistance
• White and Black/Dark Grey
• 1 to 1 Mix Ratio
In applications requiring adhesion, priming will be required for many of the silicone encapsulants. For best results, the primer should be applied in a very thin, uniform coating and then wiped off after application. After application, it should be thoroughly cured prior to application of the silicone encapsulant.
Thoroughly mixed silicone encapsulants may be poured/dispensed directly into the container in which it is to be cured. Care should be taken to minimize air entrapment. When practical, pouring/dispensing should be done under vacuum, particularly if the component being potted or encapsulated has many small voids. If this technique cannot be used, the unit should be evacuated after the silicone encapsulant has been poured/ dispensed. MC silicone encapsulants may be either room temperature (25 °C/77 °F) or heat cured.
POT LIFE AND CURE RATE
Cure reaction begins with the mixing process. Initially, cure is evidenced by a gradual increase in viscosity, followed by gelation and conversion to a solid elastomer. Pot life is defined as the time required for viscosity to double after Parts A and B (base and curing agent) are mixed and is highly temperature and application dependent. Please refer to the data table.
USABLE LIFE AND STORAGE
Shelf life has 12 months after the production date.
Containers should be kept tightly closed and head or air space minimized. Partially filled containers should be purged with dry air or other gases, such as nitrogen. Exposure to moisture could reduce adhesion and cause bubbles to form.
