A refrigerator, comprising:
- a main body;
- a door connected to the main body and configured to open and close to respectively open and close the main body;
- a storage compartment disposed in the main body to store food, wherein an exterior material of the main body includes:
- a frame including a metal material,
- a primer layer disposed on the frame,
- a base layer disposed on the primer layer and including a first bio-based resin,
- a clear layer on the base layer and including a second bio-based resin, and
- wherein the base layer and/or the clear layer contain biomass and an inorganic additive.
A home appliance comprising:
- an exterior material including:
- a frame including a metal material,
- a primer layer disposed on the frame,
- a base layer disposed on the primer layer and including a first bio-based resin, and
- a clear layer disposed on the base layer and including a second bio-based resin,
- wherein the base layer and/or the clear layer include an inorganic additive, and
- a content of the inorganic additive in the base layer is 0.2 wt % to 0.6 wt % relative to a total resin weight of the base layer and/or a content of the inorganic additive in the clear layer is 0.2 wt % to 0.6 wt % relative to a total resin weight of the clear layer.
A washing machine, comprising:
- a main body including an opening formed in a front surface thereof;
- a tub in the main body and configured to receive water;
- and
- a rotatable drum in the tub,
- wherein an exterior material of the main body includes:
- a frame including a metal material,
