Two component epoxies feature unique versatility in application and performance. These systems consist of a resin and a hardener that can be formulated to offer a wide range of mechanical, thermal, optical and electrical properties. While mix ratios differ, they all offer the ability to cure at ambient temperatures or at elevated temperatures for faster cures.
Advantages of Two Component Epoxy Systems
Master Bond two part epoxy adhesive systems can produce assemblies mechanically equivalent to or stronger than conventional metal fastened parts at a lower cost and weight. They also offer:
- Resistance to vibration and shock
- Ability to withstand thermal cycling
- Fast cures at ambient temperatures
- Gap filling capability
- Exceptional adhesion to similar and dissimilar substrates
- Uniform stress distribution
- Long-term durability
- Easy application
- Solvent free formulation
- Dimensional stability
Special Certifications for Two Component Epoxy Adhesives, Sealants, Coatings and Potting Compounds
Many of Master Bond’s two part adhesives, sealants and coatings are approved for use in various applications and industries including:
- NASA low outgassing
- USP Class VI for biocompatibility
- FDA CFR 175.300 for food applications
- UL94V-0 specification for flame retardancy
- Halogen free
Special Packaging Simplifies Using Two Part Epoxy Compounds
Many Master Bond two part epoxy systems are available for use in dual cartridges, FlexiPak® flexible divider pouches, Semkits® and premixed and frozen syringes. These premeasured time saving products are easy to dispense in multiple viscosities, minimize waste, maximize shelf life and protect against moisture. Dual cartridges are frequently applied from a manual or pneumatic gun. Ready to use premixed and frozen syringes can be easily stored and then thawed, will eliminate weighing errors and concerns over air entrapment. Dependable, consistent, high quality packaging procedures meet rigorous standards to ensure top results.
