APAO--Impact strength improver and thickener in protective& marine coating
APAO is a modifier for brittle resin like epoxy resin.
Epoxy resin coating is one of the most widely used coating products thanks to the superior stickness to metal and the mechanical&chemical performance of epoxy resin. However, after curing the epoxy resin coating tends to be brittle, which results in bad anti-impact performance and peeling strength.
1. APAO is used in epoxy resin coating formulation as an non-active impact strength improver as well as carrier resin, which facilitates to keep the coating intact for long time to assure the anti-corrosion performance.
2. APAO improves the high temperature property of the epoxy resin coating, especially in circumstances of high moisture.
3. APAO also works as thickener, helping to raise the filling rate.
4. APAO improves the anti-UV performance of the coating.
