Functional characteristics of epoxy resin fixture
Functional characteristics of fixare din rasina epoxidica
1. Various forms: various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications on the form, and the range can be from very low viscosity to high melting point solids.
2. Întărire convenabilă: Alegeți o varietate de agenți de întărire diferiți, iar sistemul de rășini epoxidice poate fi întărit la un interval de temperatură de 0~180℃.
3. Strong adhesion: The inherent polar hydroxyl and ether bonds in the molecular chain of epoxy resin make it highly adhesive to various substances. The shrinkage of epoxy resin is low when curing, and the internal stress generated is small, which also helps to improve the adhesion strength.
4. Low shrinkage: The reaction of epoxy resin and curing agent is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy group in resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage during curing.
5. Proprietăți mecanice: Sistemul de rășină epoxidice întărită are proprietăți mecanice excelente.
6. Proprietăți electrice: Sistemul de rășină epoxidice întărită este un material izolant excelent, cu proprietăți dielectrice ridicate, rezistență la scurgeri la suprafață și rezistență la arc.
7. Chemical stability: Generally, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy system, the chemical stability also depends on the selected resin and curing agent. Appropriate selection of epoxy resin and curing agent can make it have special chemical stability.
