Master Bond Released Heat-Resistant Epoxy System
The company introduced a new acid-resistant paste designed for demanding industrial bonding applications.
Updated on Oct. 1, 2026 in Materials Science
Master Bond has launched EP62-1HTND, a two-component epoxy system engineered to maintain structural integrity in extreme temperature conditions. The material is formulated for high-performance sealing and bonding tasks where chemical resistance is required.
Why it matters
This material provides a specialized solution for industrial environments that encounter corrosive acids and extreme heat. Its development addresses the need for sealants that remain stable under harsh chemical and thermal stress.
The system features a service temperature range of -60°F to +450°F and a tensile strength of 10,000-11,000 psi at room temperature. It requires an elevated temperature cure schedule for optimal performance, including a recommended post-cure of 3-5 hours at 212-302°F.
The players
Master Bond
Master Bond is a manufacturer of specialized adhesives, sealants, coatings, and potting compounds for industrial applications.
The details
The EP62-1HTND is a non-drip paste with a 100:5 mix ratio by weight, offering 12-24 hours of open time at room temperature. It provides resistance to acids such as nitric, sulfuric, and hydrochloric, while maintaining a Shore D hardness of 80-90.
Timeline
Master Bond announced the product release on October 1, 2026.
The Big Picture
This development follows the performance metrics established by the ASTM D3418 glass transition temperature measurement standard. The reported 145-155°C range reflects a shift toward higher thermal thresholds in advanced chemical-resistant adhesives.
Engineers and industrial designers can utilize this epoxy to create seals for equipment exposed to corrosive chemicals at high heat. It offers a practical alternative for sealing applications where standard, lower-temperature materials would fail under thermal or chemical load.
The takeaway
The introduction of EP62-1HTND highlights the industry trend toward materials that bridge the gap between structural strength and chemical durability. Professional users should ensure their facilities can accommodate the required elevated temperature cure schedule for optimal results.
