Filling Silicone for LED Wall Lamp
Product characteristics and applications:
It is a two-component condensated liquid silicone rubber vulcanized at room temperature. It has the advantages of low viscosity, low hardness, good toughness, good adhesion with epoxy resin, copper, iron, aluminum and other materials. It has excellent insulation, moisture-proof, shock-proof and thermal conductivity. It is suitable for filling various electronic components to make electronic components safe under harsh conditions. Full operation.
Mainly used for wall lamp, spotlight, buried lamp, power supply and other filling, with heat conduction, heat dissipation, waterproof and other functions.

Usage method:
1) Stirring: Before mixing, component A needs to be stirred in the barrel for 5-7 minutes with manual or mechanical equipment. The agitator should be placed at the center of the liquid level. The best depth of the agitator inserted into the rubber is 1/2-2/3 of the depth of the glue. Component B should be shaken about 5-7 times in the sealed state before use.
2) Mixing: The two components must be completely mixed according to the weight ratio A:B=10:1. Mixing can be done manually or with equipment. If the ratio needs to be changed, the test should be carried out before it can be used in practice. The more B component is used, the shorter the operation time and curing time. The higher the ambient temperature, the shorter the operation time and curing time. Generally, heating is not recommended to avoid pinholes or bubbles on the surface and inside, which will affect the aesthetics and sealing performance of the product.
3) Debubbling: In air-sensitive applications, products need vacuum evacuation after stirring.
4) Working time: At 25 C, the viscosity of the product will increase with the increase of time. When used, it should be ready-made and completed in a short time (30 minutes). Do not pour excessive blended rubber into the remaining rubber container.
Storage, transportation and precautions:
1) The product should be sealed and stored in a cool, dry and ventilated place (5 25 C) to prevent rain and sunlight exposure.
2) At room temperature, the storage period of A gum is 12 months and B gum is 6 months. After long storage, the filler in the gum will settle. Please mix evenly and use it without affecting the performance.
3) This product is a non-dangerous product, but we should pay attention to avoiding the contact between curing agent and skin and eyes. Once contacted, we should immediately clean it with appropriate amount of detergent and water, such as splashing into eyes, washing it with flowing water for at least 15 minutes, and consulting a doctor.
4) After the product is opened, it should be used up as soon as possible. The unused product should be stored in a safe place sealed.
5) This product is non-dangerous and can be stored and transported according to general chemicals.
6) Because of the reaction mechanism, the electrical properties of the product should be tested after 72 hours.
Packing specification:
The product is packed in 10kg/plastic drum and 2L/plastic drum for curing agent.
