product description
 

This series of products is a general-purpose room temperature liquid silicone rubber packaged in two components. When using, mix the A glue and the B glue well and it can be cured into an elastomer at room temperature. The cured product has excellent electrical insulation, thermal conductivity, arc resistance, corona resistance, water resistance, ozone resistance, weathering resistance, and can be Long-term use within -50~250°C. This series of products also have the characteristics of a variety of grades of viscosity and mechanical properties to choose from. GT-81 5 series room temperature vulcanized silicone rubber is mainly used for potting and coating of electronic components, LED series products, instruments and meters, and as a mold printing material. It has the functions of moisture resistance, shock resistance, heat dissipation, insulation and thermal conductivity. It is suitable for potting of electronic components and components generally required by potting.
 

Instructions
 

Before use, stir the A component evenly, then take 10 parts of the A group and 1 part of the B group (weight ratio) and mix them well, pour them into the potted electronic components, and gradually solidify into an elastic solid at room temperature. .
 
Once the A and B components of this product are mixed, a chemical reaction begins to occur, and the viscosity of the rubber compound begins to gradually increase (it will not increase significantly within the allowable operating period). use to avoid waste.
 
Note that the operating time will be affected by the following factors: if the amount of crosslinking agent is large, or the ambient temperature is high, the vulcanization process of the rubber will become faster. On the contrary, the vulcanization will slow down.
 
If air bubbles are generated during mixing, the mixed rubber can be vacuumed first and then poured. There are no entrained air bubbles in the device.
 
The cross-linking agent of component B is easy to deteriorate after absorbing moisture, so it should be stored in an airtight state, especially after each use, be sure to cover the lid of the packaging bucket.
 
Recommendations for using the ratio: In winter, it can be configured according to the upper limit of the ratio of the two components A: B, in summer, according to the lower limit, and in spring and autumn, it can be configured according to the average ratio.
 
 

technical parameter

※The above mechanical and electrical properties are measured at 25°C and 60% relative humidity after curing for 6 days.
