LED power special waterproof potting effect, easy maintenance retardant + thermal

Features (10: 1) tolerance of the silicone gel ▲ ▲ two component room temperature curing, fast curing completely, 1-3 hours NSL-1120-A / B switch power potting ▲ solvent-free, non-corrosive non-volatile ▲ ▲ thermal of this product is a two component room temperature curing silicone encapsulants, is the power switch sealing surface for the design of a silicone potting materials, suitable for use in harsh environments (such as moisture, vibration and corrosion applicable ● as a power switch in waterproof seal. seal protection in electronic circuit boards and components. This product overcomes the single group ● used for other lines of waterproof potting boxed Sectional deep slow curing silicone potting shortcomings table Meanwhile cured with ● used as electrical lighting waterproof seal. There are excellent process performance, insulating sealing performance. arc resistance electric ● thermal conductivity material used for electronic appliances Halo, anti-aging, high temperature resistance, suitable for large area deep bonding seal casting and injury. This product has excellent thermal conductivity. no corrosion of electronic components, it does not affect the function of electronic components. Packing material main properties ● A 25 kg plastic drum / project performance table B feed 2.5 kg plastic bottles before curing) A component B component ● A plastic bottle feed 10 kg / Appearance white or black or gray or yellowish transparent viscous colloidal liquid B feed 1 kg plastic bottles. Viscosity 7000-10000cps 70-130cps proportion 1.25-1.28 0.98-1.01 valid and storage ratio A: B = 100: 10 ● stored below 25. 60-70 C in the shade operative time (adjustable) minutes dry environment, the shelf life of six months. Curing time 50-60 minutes (full cure 24 hours) (after curing) Hardness: 30 ± 5 (Shore) thermal conductivity of 0.65 ≥1.8mpa tensile strength elongation at break ≥100% volume resistivity ≥1 × 10 * 15? .com breakdown voltage ≥17kv / mm temperature range -60-200. C Use ▲ separately before use to mix both the A component material, the B component shake, weighing ingredients. ▲ rata (10: 1) weighing A, B component, → will be A, B component into the mixing container, stir, → the mixture into the vacuum container, degassing process (mixture in a vacuum container, under pressure deaeration 0.006Mpa 5 minutes), → the material poured after degassing to be sealed products. Low-voltage electrical or potting less than 6 mm depth can not degassing process. Notes 1. Adjust the gel time: the amount of change can be adjusted using the B-component gel time (ie operating time), increasing the amount of B-component gel time can be shortened to reduce the amount of gel time may be extended. Users may need to be adjusted within the range of ± 20% according to the actual situation. 2. About mixed plastic: a, A and B components were mixed ingredients, you can use the manual, you can use mechanical mixing method, mixing speed should avoid prolonged stirring high temperature (do not higher than 38 ℃), so as not to shorten operation time and accelerate the curing, resulting in too late to operate. b, by the surface of the potting products must be cleaned before potting. c, should be stirred manually will adhere to the bottom of the container and the side of the rubber to the middle folded several times (to make full contact with the compound A component B component). 3. Usually low-voltage electrical potting can not degassing, if high-voltage electrical potting it must be subjected to vacuum degassing potting. 4. Plastic material and hardener should be sealed. The mixed plastic materials should be run out of time to avoid wastage. 5. This product is non-dangerous goods, but not imported and the eye. 6. This series of plastic release low molecular weight substances in the curing process, the relatively high temperature requirements (such as 7 days or more resistant 1 80 ℃), can be used colloidal gel in 5 hours after heating for several hours (generally warming Subsequent temperature is less than 60 ℃, 2 ~ 24 hour access) accelerated curing process, so that the temperature of the colloidal great help. (Remember not other small molecules released and used in the fully enclosed electronic vitality in.) 7. Group B is divided into transparent liquid, with time, the color may be yellow or slightly stratified slowly, but does not affect the use of the product. Adverse reactions and a treatment method: silicone and rosin tolerance will lead to conflict, resulting in the phenomenon of 1, will lead to a weld will not solidify, but not completely cured, over time, usually a week later will naturally complete cure. 2 generated phenomenon, the phenomenon will cause the surface layer of oil supply, it is recommended before using the line subjected to ultrasonic cleaning and then to Glue. Two: tolerance and hot-melt silicone will produce conflict, resulting in a phenomenon, completely cured. Products phenomenon 2, can be cured but not solid, easy out.
