Background
The polysiloxane coating is divided into acrylic polysiloxane and epoxy polysiloxane.

In addition, compared with the traditional epoxy resin technology, the acrylic modified polysiloxane coating has the same corrosion resistance and slightly superior mechanical properties. Currently, there are two main types of acrylic polysiloxanes: one is the addition and hydrolytic condensation between acrylic resin containing double bonds and siloxane, and the other is the hydrolytic crosslinking reaction between acrylic resin polysiloxane intermediate and alkylamino. The former can be thickly coated, but the reaction is complex, the influence by the environment is large, and the influence on the later-period resistance of the coating is large; the latter is generally suggested as a thin coating, and is greatly affected by air humidity, and is inferior in gloss stability, so that acrylic polysiloxane is limited in practical application and popularization.
