• Low modulus urethane
• High purity
• Low outgassing
• 4/1 PBV dual cartridge kits

PRODUCT DESCRIPTION

APTEK 2125-A/B is a two component, lightweight, electrically insulating urethane system designed for the potting and encapsulation of electronic components, substrates, and active chips. This is 100% solids, solvent free system that will not form voids during cure or service life.

APTEK 2125-A/B is a non-TDI based urethane system which has outstanding reversion resistance and physical stability when subjected to high heat and humidity environment. As a urethane, this system displays higher ionic purity than epoxy systems minimizing the chance of corrosion around sensitive components and circuitry.

KEY FEATURES AND BENEFITS

• Low modulus/high elongation to minimize stress to sensitive components and ceramic substrates.
• Low Tg for excellent low temperature cycling and performance
• Wide operating temperature range (-65°C to 100°C) for versatility.
• Excellent substrate adhesion; superior to silicones
• Exceeds NASA outgassing requirements for high vacuum environments
• Low density for aerospace applications
