kafuter K-5312 electronic pouring glue two-component silicone potting adhesive resistance high temperature sealant
K-5312 two-component silicone pouring sealant room temperature curing, good deep curing properties,good adhesion to rubber, rubber low viscosity easy deaeration. After the adhesive cured elastomer material with excellent resistance to hot and cold properties and resistance to outdoor aging. Purpose:
This plastic material of all kinds of metal, most plastics have a certain degree of adhesion (epoxy resin, polycarbonate, nitrile rubber, EPDM rubber and other good adhesion), thereby make rubber material and components and wall linked closely together, having better sealing performance. LED module suitable for potting protection, general electronic components, modules and circuit boards. Performance K-5312 Before curing
Appearance A: Black Fluid B: colorless, transparent liquid Viscosity (25 , mPa · s) A: 2000 ~ 4000 B: 20 ~ 100 The relative density (25 , g / m3) A: 1.10 ~ 1.25, B: 0.98 The mixing ratio(%) A: B = 100: 10 Operating time (25 , min) 30 to 60 After mixing Viscosity (25 , mPa · s) 1500-3500 Full curing time (25 , h) twenty four After curing
Shore A hardness (24h) 15 to 25 Thermal conductivity (w / (m.k)) 0.3 Volume resistivity (Ω · cm) 1.0 × 1014 Dielectric strength (kv / mm) ≥18 Dielectric constant (100KHZ) 2.9 Shear strength (MPa, aluminum / aluminum) ≥1.0 Dielectric loss tangent (100KHZ) 1.0 ~ 3.0 × 10-3 Precautions:
1.When there will be long-term storage component A settlement or stratification, so before each mixing component A need to use the appropriate manual or mechanical stirring, component B should be fully shaking the container in a sealed condition, then use. 2.When attached to the required application materials before use to confirm whether the attachment, and then apply. 3. are mixed, the amount of component B is more general, the shorter the curing time, the shorter the operating time. 4.the higher the temperature, the faster the cure, the shorter the operating time. Heat curing is generally not recommended in order to avoid surface and internal bubbles or pinholes, affect the appearance and sealing performance. 5.the sealing thickness 20mm or less naturally degassing, without prior degassing. If large potting thickness, surface and internal bubbles or pinholes may occur, therefore, the mixture should be placed in a vacuum container, degassing under 700mmHg at least 5 minutes. Packaging, storage and transportation:
(1) The product points A, B component separately packaged: 1.1KG / set (A group 1KG + B component parts 0.1KG), (shop sold specification 1.1KG / group) 22KG / set (A component 20KG + B component 2KG). 22kg specifications please contact customer service needs (2) when the goods storage and transportation, should be stored in a cool dry place, avoid the sun and rain. The following (3) 25 products effective storage period is one year. Extended retest, if they meet the standards can still be used. (4) This product is non-dangerous goods storage and transportation. 1. Accurate measurement weighing A and B component. 2. The stirring component B component A flask equipped with a container and mix well. 3. pouring the mixed plastic material as soon as possible the need for potting potting products. 4. cured potting good parts left at room temperature curing, after the fixture can enter the next step, complete curing takes 10 to 24 hours Time.
