Answer 2

Varnish is a homogeneous colloidal dispersion solution of resin in oil or thinner or both.

• Varnish is a mixture of synthetic or natural resin, drying oil, a volatile solvent like thinner.
• When this mixture is applied on surfaces, the volatile solvent evaporates in some time and the other materials polymerize.
• This process ends with forming a transparent film-like layer that is durable, shiny, and protective.
• The resin can either be derived from plants or insects or formed synthetically.
