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.
