Master Bond Released High-Heat Epoxy System
The new EP62-1HTND two-component epoxy offers high chemical resistance and thermal stability for industrial applications.
Updated on Oct. 5, 2026 in Materials Science
Master Bond has introduced the EP62-1HTND, a two-component epoxy system engineered for bonding and sealing tasks that require durability in extreme environments. This material is specifically formulated to withstand high temperatures and resist exposure to various acids, bases, and solvents.
Why it matters
The development of high-performance adhesives like the EP62-1HTND is critical for industries that rely on structural integrity under intense heat and chemical stress. This system provides a specialized solution for engineering challenges where standard materials might fail.
The EP62-1HTND features a glass transition temperature of 145-155 °C and maintains a volume resistivity exceeding 10^14 ohm-cm at 75 °F. It also exhibits a Shore D hardness of 80-90 and functions across a service temperature range of -60 °F to +450 °F.
The players
Master Bond
Master Bond is a leading manufacturer of specialized adhesives, sealants, coatings, and potting compounds for a wide range of industries.
The details
The epoxy system requires a specific mix ratio of 100:5 by weight to ensure optimal performance. To achieve its full mechanical and chemical properties, the material requires an elevated temperature cure schedule during the application process.
Timeline
Master Bond released the new EP62-1HTND epoxy system on October 5, 2026.
The Big Picture
The introduction of the EP62-1HTND reflects a broader shift toward advanced thermosetting polymers that can operate in increasingly extreme industrial conditions. This product follows a trend in materials science to replace mechanical fasteners with chemically inert bonds that survive harsh environmental degradation.
For industrial manufacturers, this epoxy could lead to more durable, longer-lasting equipment components that require less frequent maintenance or replacement in chemically active environments. In the long term, this technology may support the development of more reliable hardware in sectors like aerospace or chemical processing.
The takeaway
This new epoxy provides a specialized solution for environments where standard adhesives would likely degrade due to high thermal or chemical exposure. Engineers should ensure they have the infrastructure for an elevated temperature cure schedule before integrating this material into production.
