Abstract
Provided is an anti-fingerprint coating material for a stainless steel outer case of a home appliance. The coating material includes: polysilicate having 27.6 parts by weight to 36.2 parts by weight; one of epoxy resin and vinyl resin having less than 10.6 parts by weight; colloidal silica having 21.2 parts by weight to 42.6 parts by weight; and an additive having less than 10.6 parts by weight and including at least one hydrophile material selected from the first group consisting of —OH, —NH2, and —COOH and at least one hydrophobic material selected from the second group consisting of —CnF2n+1 and —SiR3.
Claims5
An anti-fingerprint coating material for a stainless steel outer case of a home appliance, comprising:
- polysilicate having 27.6 parts by weight to 36.2 parts by weight;
- at least one of an epoxy resin and a vinyl resin having less than 10.6 parts by weight and more than 0 parts by weight;
- colloidal silica having 21.2 parts by weight to 42.6 parts by weight;
- and
- an additive having less than 10.6 parts by weight and more than 0 parts by weight, the additive including at least one hydrophilic material selected from a first group consisting of —OH, —NH2, and —COOH and at least one hydrophobic material selected from a second group consisting of —CnF2n+1 and —SiR3.
An anti-fingerprint coating composition which comprises:
- a polysilicate;
- at least one of an epoxy resin and a vinyl resin present in an amount greater than 0 and up to less than 10.6 parts by weight;
- colloidal silica;
- and
- greater than 0 and up to less than 10.6 parts by weight of an additive containing at least one hydrophilic material selected from a first group consisting of —OH, —NH2, and —COOH and at least one hydrophobic material selected from a second group consisting of —CnF2n+1 and —SiR3.
