Two component epoxy system for bonding, sealing, coating, and casting

Key Features

  • Convenient handling
  • Cures at ambient or elevated temperatures
  • Good electrical insulation properties
  • Outstanding physical strength

Product Description

Master Bond EP21LVTK-2 is a two component, room temperature curing epoxy adhesive, sealant, coating, and encapsulating system featuring outstanding physical properties, superb dimensional stability and low shrinkage upon curing. This moderate viscosity system has a very forgiving 1 to 1 mix ratio by weight or volume. In fact, EP21LVTK-2 has the unusual feature of allowing the properties of the cured system to be altered by tweaking the mix ratio. Adding more Part A (maximum allowed 2:1 mix ratio by weight) will give a more rigid cure, which allows for better machinability. Adding more Part B (maximum 1:2 mix ratio by weight) offers a more forgiving cure, allowing for enhanced impact and shock resistance. Please note the various curing schedule options in the full data sheet.

It bonds well to a variety of substrates including metals, composites, glass, ceramics and many rubbers and plastics. EP21LVTK-2 withstands rigorous thermal cycling and shock. It also withstands many chemicals including water, oils, fuels and many acids and bases. It is serviceable over the wide temperature range of -60°F to +250°F. The color of Part A is translucent and Part B is amber. Once cured, EP21LVTK-2 is a highly reliable electrical insulator. EP21LVTK-2 is truly a versatile system and can be used in electronic, medical, aerospace, optical and OEM applications, among others.
