Paint Industry and Market
- The global paints and coating market was valued at $121.9 billion in 2014.
- The decorative paints and coatings subsector is heavily dependent on the construction sector.
- The dominant product segment of the paints and coatings industry in 2014 was decorative paints and coatings.
- The Asia-Pacific region dominated the global paints and coatings market in 2014.
Paint Benefits and Limitations
- A good paint provides durability, corrosion resistance, and weather resistance.
- The main limitations of enamel paint are its high gloss finish, tendency to yellow over time, and brittleness.
- The main components of an excellent-quality paint mix are binder, solvent, pigment, and additives.
Paint Coatings and Surface Preparation
- The main characteristic that characterizes the durability of finishing coatings is its resistance to corrosion and wear.
- The formula that defines the probability of destruction of protective and decorative coatings is P = 1 - (1 - P0) ^ (n ^ a).
- The modulus of elasticity (Eupr) is calculated for each sample using the formula Eupr = (Fmax - Fmin) / (ΔL / L0).
- Increasing roughness affects the strength and deformations of paint coatings negatively.
- The surface roughness of the paintwork was evaluated using the method of atomic force microscopy.
