Abstract
Official abstract text for this publication.
A composite resin includes an acrylic resin constituent unit, an epoxy resin constituent unit, and a polysiloxane constituent unit. A proportion of the polysiloxane constituent unit in the composite resin is 1.5 weight % to 12 weight % in terms of SiO 2 . When the composite resin is used, it is possible to provide a coating film having high corrosion resistance.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composite resin comprising: an acrylic resin constituent unit; an epoxy resin constituent unit; and a polysiloxane constituent unit wherein a proportion of the polysiloxane constituent unit in the composite resin is 1.5 weight % to 12 weight % in terms of SiO 2 . 2 . The composite resin according to claim 1 , wherein the proportion of the polysiloxane constituent unit in the composite resin is 2 weight % to 10 weight % in terms of SiO 2 . 3 . A coated substrate comprising: a substrate; and a coating film that covers the substrate and includes the composite resin according to claim 1 . 4 . The coated substrate according to claim 3 , wherein the substrate is a metal substrate having hydroxyl groups on a surface of the metal substrate. 5 . The coated substrate according to claim 3 , wherein the coating film has a thickness of 1 μm to 50 μm.
