Epoxies for Bonding Kevlar Substrates

Bonding Kevlar*

Kevlar is a resilient, tough, exceptionally strong organic fiber. It is available for use in many different types. Kevlar absorbs vibration, has high tensile strength to weight ratio and withstands impact. It has superior resistance to flames, cutting, most chemicals and is stronger at low temperatures. Additionally it offers a high modulus, dimensional stability and low thermal shrinkage.

Five times as strong as steel, kevlar is used in a wide range of applications inculding:

  • Military body armor
  • Sporting goods
  • Firefighter gear
  • Aircraft structural parts
  • Ropes
  • Auto components
  • Industrial gloves
  • Hydraulic hoses
  • Seals and gaskets

Considerations for Adhesive Bonding Kevlar - High Temperature Resistance

Preferred adhesives for bonding Kevlar include Supreme 11HT, EP21TDCHT and EP3HT. High shear and peel strength epoxy adhesive system Supreme 11HT cures at room temperature. It exhibits resistance to stress cracking fatigue and impact. Master Bond EP21TDCHT is serviceable up to -100°F to +350°F. This tough compound withstands thermal cycling while retaining dimensional stability. One component, no mix EP3HT cures quickly at elevated temperatures. This product has excellent bond strength, electrical insulation properties and can be applied on vertical surfaces without sagging.
