KE-347 is a medium-viscosity silicone sealant designed for flow coating and conformal coating. It comes in a single-component, room-temperature-curing form and can be applied directly by dispensing or brushing, without the need for mixing. The sealant offers a smooth, smooth coating line and is available in black, white, and translucent finishes to perfectly match the substrate's appearance. It has a virtually non-irritating odor upon application and is not prone to discomfort even during extended application. It is available in portable tubes and standard cartridges, suitable for applications ranging from proofing and small batches to continuous coating on a production line.

• Stable Viscosity - At 25°C, KE-347 has a viscosity of approximately 55 Pa·s, placing it in the medium viscosity range. This allows for self-leveling after spraying or brushing, while also being non-sag-prone. Based on a typical film thickness range of 200 to 500 microns, the balance between viscosity and flowability keeps average thickness fluctuations within ±10%, ensuring consistent coating thickness and reducing rework.

  
  

• High Heat Resistance - Continuous heat resistance reaches 180°C, meeting the requirements for long-term use around high-temperature components or near power modules after reflow soldering. Combined with its room-temperature curing properties, the cured coating exhibits minimal dimensional change during thermal cycling and is less prone to cracking within a thickness range of 200 to 500 microns, making it suitable for protective coatings around heat-generating components.

  
  

• Electrical Insulation - With a dielectric strength of approximately 20 kV/mm, KE-347 provides reliable electrical isolation even at extremely thin coating thicknesses. With a 0.3mm coating, the theoretical withstand voltage can reach over 6 kV, sufficient to meet the creepage clearance reinforcement requirements of most low-voltage power and signal boards.

  
  

• Balanced Thermal Conductivity - The thermal conductivity is approximately 0.21 W per meter Kelvin, a medium thermal conductivity level. This helps dissipate heat within the coating without forming an overly rigid, highly thermally conductive interface. For control boards with low power consumption, a coating of 200 to 300 microns can reduce surface temperature rise by several degrees, helping to extend component life.

  
  

• Coverage - A standard 330ml package with a 200µm film thickness can theoretically cover approximately 1.65 square meters, while a 500µm film can cover approximately 0.66 square meters, facilitating unit cost and stock quantity calculations based on production line cycle times.

  
  

• Flexible Specifications - Available in two common sizes: 100g and 330ml, they cater to pilot runs, maintenance, and mass production scenarios. Available in black, white, and translucent, the product can be distinguished by color, ensuring consistent use across different process areas or versions, reducing the possibility of product mix-ups.

  
  

• Compatible Adhesion - Excellent adhesion to a variety of substrates, including metals, plastics, glass, and ceramics, allowing for coating and sealing on common unprimed materials. A 330ml bottle, when used with conformal coating equipment, allows for stable coating times of several hours per shift. The coating also minimizes edge curl, minimizing shrinkage stress transfer during subsequent curing, promoting long-term stability of connectors, pins, and pads.

• Electronics Tri-Proofing - KE-347 is suitable for surface coating and component pin reinforcement on printed circuit boards (PCBs), typically performed as a secondary process after wave soldering or reflow soldering. Designed with a process thickness of 200 to 300 microns, a 330 ml cartridge can cover approximately one to two square meters of board surface, meeting the needs of small-batch SMT production.

  
  

• Automotive Electrical - KE-347 can be used for sealing rear headlight covers, coating sensor signal boards, and protecting charging ports. Assembly operations are often performed at workstations, and small cartridges can be used to perform repairs or local reinforcement, minimizing line downtime.

  
  

• Home Appliance Control - KE-347 is suitable for protecting control panels for air conditioners, washing machines, water heaters, and small kitchen appliances. The typical coating volume per device is 8 to 15 ml. A standard cartridge can support an assembly cycle of 20 to 40 units, facilitating quantitative production on the production line.

  
  

• Aerospace and Defense - KE-347 can be used as an encapsulation material for airborne electronics, connector tails, and wiring harness branches. Due to long maintenance cycles and limited on-site spare parts space, the 100g small package is convenient for portability and batching, reducing excess material waste.

  
  

• General Industry - KE-347 is suitable for sealing and coating factory electrical cabinets, inverters, power modules, and sensor housings. Maintenance teams can schedule centralized coatings according to quarterly inspections, using the 330ml package to quickly reinforce large areas. For production lines that require overnight operation, the 100g small package can be used to reinforce key areas before re-coating the entire surface during downtime.
