Epoxy is a thermosetting polymer formed from reaction of an epoxide “resin” with polyamine “hardener”. Epoxy has a wide range of applications that include fiber reinforced plastic materials and general purpose adhesives. When these two are combined they formed a secure bond. The process of polymerization is called “curing”, and can be controlled through temperature and choice of resin and hardener compounds; the process can take minutes to hours. Some formulations benefit from heating during the cure period, whereas others simply require time and ambient temperatures.
The most common packaging types for epoxies are dual pouch clip systems, dual cartridges, and syringes. The mixed ratios of 1:1, 2:1, 4:1, and 10:1 are generally used with these packaging types. Some epoxies are pre-mixed / frozen to stop the curing process and then heated to room temperature to be used for the desired applications.
Each machine is cleaned with a general solvent that will eliminate any contaminates to the material after each production run.
