LED power supply thermal retardant electronic potting TY5299, military quality, factory price

LED power supply thermal retardant electronic potting TY5299, military quality, factory price First, the product features TY- 5299 is a low viscosity two-component addition silicone encapsulants can be cured at room temperature or heat cured with temperature The higher the faster the cure characteristics. The goods in the curing reaction does not produce any by-products can be applied to the surface PC (Poly-carbonate), PP, ABS, PVC, etc. and metal class. Full compliance with EU ROHS directive. Second, the typical use of the power module potting potting protection to protect other electronic components Third, the technical parameters of performance indicators A component B component fluid before curing the appearance of gray white fluid viscosity (cps) 2500 ~ 3500 2500 ~ 3500 mixing ratio A : B (weight ratio) mixed 1 after Viscosity (cps) 2500-3500 applies Time (min) 30-50 (adjustable) Molding Time (h) 4-6 Curing time (min, 90 ℃) 15 Hardness after curing (shore A) 40-50 Thermal conductivity [W / mK] 0.8 Dielectric strength (kV / mm) 22 dielectric constant (1.2MHz) 3.12 Volume resistivity (Ω · cm) 1.8 × 1015 gravity (g / cm3) 1.56 ± 0.03 before curing performance data above are at 25 ℃, relative humidity of 55% under the conditions of the measured mechanical properties and electrical properties of the sample after data are fully cured measured. The company's test conditions caused by different or product improvement data different will not take the responsibility. Fourth, the use of technology 1, before mixing: First, the A and B components in their respective container, stir; 2, mixed: A component shall comply with: B component = 1: 1 weight ratio, and Stir; 3, discharge bulbs: rubber vacuum exhaust mixture should bubble for 1-3 minutes; 4, potting: The mixed material should be poured into a plastic irrigation products as quickly as possible, in order to avoid late gum thickening and illiquid Good; 5. Cure: heat curing at room temperature can be. The higher the temperature, the faster the curing. When the temperature is low, the curing time to be extended. In the winter, take a long time to cure, it is recommended heating curing, cured for 15 minutes at 80 ~ 100 ℃, at room temperature normally takes about 12 hours to cure. V. Notes 1, plastic materials should be sealed and stored in a dry environment at room temperature, mixing a good plastic material should be used as soon as possible, to avoid wastage. 2, the product is non-dangerous goods, but not imported and the eye. 3, non-toxic, has good physical inertia, skin irritation and injury. The product does not contain flammable ingredients, will not cause a fire and explosion, no special requirements for transportation. 4, after a period of storage, plastic may be layered. Please stir well before use, do not affect performance; 5, the following substances may hinder the curing of the product, or the occurrence of the phenomenon is not cured, so it's best to verify the application after making a simple experiment, the site of application needs to be cleaned if necessary. a, incompletely cured condensation type silicone rubber. b, the amine (amine) curing type epoxy resin. c, Ash welding process (solderflux). VI, packaging specifications and storage and transportation 1, Packaging: 20kg / group, A agent 10kg / barrel, B agent 10kg / barrel, plastic bucket; 40kg / group, A agent 20kg / barrel, B agent 20kg / barrel, plastic barrel. 2, the storage of this product is one year (less 25 ℃), exceeding the shelf life of the product must be confirmed before use exception. Seven, recommendations and declarations are recommended before using this product do first formal suitability test. As the blind use this product for any consequences arising in inappropriate situations, the company is not responsible.
