What are epoxy resins?
Epoxy resins are most important thermosetting polymers thanks to their excellent chemical, mechanical, thermal and adhesive properties. Epoxy resin is a polymer that contain the epoxide group (also known as ethoxylene or oxirane), in which an oxygen atom is bonded to two adjacent (end) carbon atoms.
Epoxy resins cure or set into a hard shape using curing method such as heat or radiation. The curing process is irreversible since a polymer network is crosslinked by covalent chemical bonds. The crosslinking of epoxy resin can be the result of an addition or homopolymerization reaction.
What is NEMresin?
NEMresin is a powdered single-component epoxy resin, which can be stored at room temperature. Its liquefies is caused by the temperature rise above 65 °C. Afterward, the resin undergoes rapid hardening. Products based on the basis of NEMresin have a wide range of mechanical, thermal and physical properties, tailored to the customer’s requirements.
It is applied on reinforcement in room temperature with a pistol or dosing equipment to the powder. Then the composition is pressing with simple tools, for example hand-press or hydraulic press without vacuum application.
