LED display potting waterproof and dustproof

I. Summary of AP-9210 is a two component room temperature curing condensation type silicone encapsulants, consists of two parts A, B liquid components. Fluidity before curing, and can be poured into the nuances; room temperature curing, without heating and baking, ethanol molecules released during curing, for PC (Poly-carbonate), PP, ABS, PVC, copper and other materials will not cause corrosion. For most electronic parts and materials (PP, PE excluded) good adhesion. Small shrinkage during curing, no case of fever temperature rise; soft elastomer after curing, good waterproof performance; strong adhesion, adhesion persistence, keeping the rubber in the range of -60 ~ 200 ℃ elasticity, excellent insulation properties. RoHS compliant environmental requirements. UV-resistant materials fully cured after anti-aging properties, good repair, with excellent weather resistance. Second, the technical characteristics of No. Test Item Specification 1 Appearance (after curing) transparent, white, black solid 2 Viscosity (mPa · s, mixed) 700 - 30 003 dry time (min, room temperature) of 20 to 1004 Hardness (Shore A) 10 ~ 50 5 Tear Strength (KN / M)> 0.6 6 Tensile strength (MPa)> 0.6 7 Elongation (%)> 708 Compressive strength (kv / mm)> 10 9 volume resistivity ( Ω · cm) 1.0 × 1013 Note: The above data room environment testing * widely used in high power electronic components, power modules, circuit boards and the LED potting protection. * Use 1. Measurement: Accurate weighing A, B (curing agent), component C; (pre-weighing component A, stir to make a slight re-settlement of the fill uniformly dispersed in the glue) 2 . mixed plastic: the B or B, and group C component is added to Part A homogeneously mixed; 3. Casting: the mixing of the components in the potting compound complete potting operations; (potting mix surface and the front part container kept clean and dry) 4. Curing: good potting parts left at room temperature curing, after initial solid into the next process can be completely cured need 8 to 24 hours. High summer temperatures, curing will be faster; low winter temperatures, curing will be slower. * Packaging and storage Packing: 22kg / set (A component 20kg, group B component 2kg), product is non-toxic and non-dangerous goods, according to general chemical handling, transportation, storage in a cool (room temperature), dry place, shelf life of 12 months.
