Curing of Organic-Inorganic Hybrid Materials
- · When blending with initiator, it becomes easily curable with thermal or UV-light
- · Appearance before curing : colorless transparent viscous liquid (Fig. 1)
· As the intermolecular cross-linking is proceeded, an organic-inorganic nano-hybrid structure is generated which is likely that organic and inorganic part is combined in molecular level
→ Transparency (Fig. 2), high hardness, high heat resistance, high weatherability
