NASA Low Outgassing Rated UV Curing Adhesive with High Glass Transition Temperature
18 Aug 2023
Master Bond UV26 is a new one-part UV curable system featuring an exceptionally high glass transition temperature (Tg) ranging from 160 to 170°C. This NASA low-outgassing certified compound also offers strong adhesion to a wide variety of substrates such as glass, surface-treated metals, and many plastics. As a coating and adhesive, it is also capable of withstanding harsh chemicals including acids, bases, fuels, and many aggressive solvents.
This low-viscosity compound (250-1,500 cps at 75°F) cures rapidly upon exposure to a UV light source at a wavelength of 320-365 nm with an energy output as low as 20-40 milliwatts per cm2. With a refractive index of 1.55 at room temperature, this system features outstanding optical clarity. UV26 offers robust physical strength properties upon curing and is ideal for high-performance bonding and coating applications. It features low shrinkage upon curing and serviceability from -60°F to +500°F [-51°C to +260°C].
Master Bond UV26 is 100% solids, does not contain any solvents or volatiles, and is not oxygen inhibited. It is available for purchase in 10 cc and 30 cc syringes, ½ pint, and 1-pint containers. The shelf life at 75°F is 6 months in the original unopened containers.
