Heat Cured Silicone Adhesives

Heat cured 1-part silicone adhesives cure in minutes reducing production time and improving output. Using platinum catalysts, they do not produce any harmful by-products, which make them suitable for a wide range of applications including electronics.

  • 1-part - no need for expensive mixing equipment
  • Neutral cure, non-corrosive
  • Thermally conductive

Adhesion promoters are added to improve adhesion across a range of substrates. As with all addition cure materials, adhesion can be improved with longer cure times, higher cure temperatures, post curing at an elevated temperature or by using a specialist primer such as CHT Primer No 3.

General Attributes:

  • Heat cure - 90°C to 150°C
  • Fast cure - in some cases less than 5 minutes
  • Neutral cure non-corrosive
  • High temperature resistance up to 260°C
  • Range of thermal conductivities up to 3.00 W/mK
  • Range of viscosities, harnesses and tensile strengths
  • Excellent adhesion to most substrates

Applications: Sealing, bonding, gasketing, electrical insulation, environmental protection, vibration control and thermal transfer.

Industries: Electronics, automotive, aerospace, LED and lighting, domestic appliances.

Finding the right silicone for your application is not limited to CHT’s product portfolio. Our technical team will partner with you to either modify specifications in a current product or custom formulate a new one to meet your exact requirements
