1. Definition of Paint: Liquid, paste or solid materials that adhere to surfaces such as metal, wood, glass, concrete/plaster, or plastic, and impart decorative, protective or functional properties. Paints provide one or more of the following characteristics to the surfaces they are applied to, depending on the intended use: 1.1. Decorative Properties: Color | Gloss | Effect (metallic, pearlescent, textured, soft feeling, etc.) 1.2. Protective Properties: Corrosion resistance | Water resistance | Resistance to chemicals (oil, acid, detergent, solvent, etc.) | Resistance to external conditions (UV rays, heat and temperature fluctuations, rain, snow, acid rain, etc.) | Resistance to physical conditions (impact, scratching, bending, abrasion, etc.) 1.3. Functional Properties: Marking | Electrical insulation or conductivity | Antibacterial protection | Camouflage against IR rays, etc. | Marking/warning | Thermochromic effect

2. Examination of Main Input Groups Comprising Paint

2.1. Resins (can also be referred to as binders) are among the most important inputs in paint formulations. Depending on the paint structure, one or more resin types are combined to provide film-forming capability after application. They determine fundamental properties of the film such as adhesion, elasticity, cohesion, and internal and external durability.

In the most general terms, water-based, solvent-based or solvent-free resins used in paint formulations:

• Alkyd resins (oil-free, short, medium, long oil) • Polyester resins (saturated, unsaturated) • Acrylic resins (thermoplastic, thermoset) • Epoxy resins (water-based, solvent-based, solvent-free) • Epoxy hardeners (polyamine, polyamide, other) • Melamine, urea-formaldehyde and benzoguanamine resins • Isocyanate hardeners (aliphatic, aromatic) • Vinyl resins • Phenolic resins • Silicone resins • Nitrocellulose resins and cellulose esters • Other
