Henkel Loctite® Stycast® 5952-1 Two-Component Silicone Encapsulant
Categories: Polymer; Thermoset; Silicone; Silicone Elastomer, for Thermal Management

Material Notes: Loctite Stycast 5952-1 provides the following product characteristics:
  • Electrically non-conductive
  • Good elongation strength
  • Moderate tear strength
  • High thermal conductivity

Cure: Heat cure

Application: Potting or Encapsulant

Typical Assembly Applications: Transformers, Rectifiers, Thyristors, Power supplies and Heat generating modules

Other Application Areas: Thermally conductive roll coatings, Heat sinks and Thermal pads

Loctite Stycast 5952-1 is designed for encapsulation of heat generating devices. It is also recommended for applications requiring a non-corrosive casting and coating.

Loctite Stycast 5952-1 may be cured over a broad range of temperatures. After 24 hours at room temperature, it will be hard enough to handle. Optimum properties will be achieved after 7 days. Loctite Stycast 5952-1 can be cured rapidly at elevated temperatures, even in thick sections. For optimum performance, follow the initial cure with a post cure of 2 hours at 175ºC.
