Master Bond has launched Supreme 10HTLV, a one-part, non-frozen, heat-cured epoxy designed for demanding structural bonding applications. 

 

“This toughened system features a moderately high viscosity with good flow, which will not thicken over time,” the company says, highlighting its reliability for replacing traditional mechanical fasteners.

 

Engineered for extreme environments, Supreme 10HTLV can endure cryogenic temperatures down to 4 K and remain serviceable at up to 400°F. It delivers long-term reliability under mechanical shock, vibration, and severe thermal cycling. 

 

“The system demonstrates excellent environmental resistance, surviving 1,000 hours at 85°C/85% RH and exhibiting strong protection against water, oils, and various chemicals,” Master Bond reports.

 

Supreme 10HTLV also packs high mechanical performance, with tensile shear strengths over 3,600 psi and T-peel strengths up to 30 pli. The epoxy is electrically insulative, offering a volume resistivity greater than 10¹² ohm-cm at room temperature, and bonds effectively to metals, glass, ceramics, and many plastics.

 

For convenience, the epoxy requires no mixing and offers two heat-curing options: 60–75 minutes at 250°F or 35–40 minutes at 300°F. It comes standard in gray, with additional colors available on request, and is offered in ½-pints, pints, quarts, gallons, and specialty containers including cartridges and syringes.

 

“With unlimited working life at room temperature, Supreme 10HTLV offers convenient storage, simplified handling, and streamlined processing,” the company says, positioning the epoxy as a versatile solution for high-demand industrial and scientific applications.
