Silicone Elastomer

1. Good flowability 2. Low cost for silicone benefits 3. Room temp or heat accelerated cure 4. 2-part 5. 1:1 mix ratio

Product descriptionQYAE301 silicone encapsulants are supplied as two-part liquid component kits. When liquid componentsare thoroughly mixed, the mixture cures to a flexible elastomer, which is well suited for the protection ofelectrical/electronic applications.

Application• General potting applications• Power supplies• Connectors• Sensors• Industrial controls• Transformers• Amplifiers• High voltage resistor packs• Relays

ProcessingBefore work, keep all the kits clean and dry, without any dust, oily and other material can influence cureand cohere of product. Open the package both A & B part, after pre-mix, supplied in a 1:1 mix ratio.Follow the ratio to mix, deairing & decompression is required, then pour into electronic instrument. Roomtemperature cure encapsulants may also be heat accelerated for faster cure. Pleaes use immediatelyafter opening the package. Airtight storage If residual.
