||1). Strong adhension. The epoxy or the PE has strong adhension with the minerals.
|2). Low curing shrinkage:
Epoxy resin and polyethylene paint are among the lowest curing shrinkage of thermosetting and thermoplastic plastics (Phenol resin is 8%--10%; unsaturated polyester resin is 4%--6%; silicone resin is 4%; organic silicone resin is 4%--8%;)The coefficient of linear expansion is also very small, which is generally 6 × 10 ~ (-5) / ℃. So the volume after curing has little change.
|3). Excellent electrical insulation
|4). Good chemical stability and excellent resistance to chemicals
|5). High Anti heat property. The usual anti heat range is 80~100℃.The heat resistance of epoxy can reach 200 ℃ or higher.
