Supreme 3HTND2GT Product Description

Master Bond Polymer System Supreme 3HTND2GT is a fast curing, toughened one component high performance epoxy adhesive/sealant which meets the growing need for precise positioning and bonding of microelectronic components and other devices on printed circuit boards and other electronic assemblies. It meets the increasing need for technology capable of accurate assemblies and manufacturer of miniaturized electronic devices without soldering and other traditional methods. It offers remarkably high durable protection against adverse enviornmental conditions, vibration, impact and thermal shock for components on circuit boards including the more fragile and delicate ones. Additionally, Supreme 3HTND2GT has excellent electrical insulation properties, high physical strength characteristics and superior adhesion to metals, plastics and ceramics, as well as to flexible and rigid circuit board materials. Supreme 3HTND2GT can be easily applied to specific, sharply defined circuit board areas and will not flow during application or cure beyond the desired board section. The most important advantages over conventional two component glob top compounds include ease of application with no need for mixing, unlimited working life, very fast cure cycles, along with high insulation and strength properties. Supreme 3HTND2GT is 100% reactive and does not emit any volatiles during cure. The formulation is specially designed so that ionic impurities are negligible.

Master Bond Polymer System Supreme 3HTND2GT has flow properties especially designed for acute positioning and bonding including glob top applications using commercially available dispensing equipment. Cures can be effected in 2030 minutes at 250°F, 510 minutes at 300°F, or even shorter times at higher temperatures. Minimum cure temperature is 230°F. Supreme 3HTND2GT has superior durability and long term dimensional stability. The cured material is highly resistant to heat, moisture and many chemicals including acids, bases, salts and many solvents. The volume resistivity exceeds 10¹⁴ ohmcm at 75°F. The service temperature range is 100°F to +400°F. Supreme 3HTND2GT has excellent storage stability with a shelf life of six months at ambient temperatures with no refrigeration required. Supreme 3HTND2GT is normally colored tan, but can be formulated in other colors as needed. Flow properties also can be tailored for specific application needs. Supreme 3HTND2GT is also available in a thermally conductive version called Supreme 3AOHTND2GT. Both versions are now packaged in syringes for convenient dispensing.
