What is the difference between water-based paint and oil-based paint.

Water-based paint and oil-based paint are two common types of paints. They have some major differences in composition, performance and application:

Solvent composition
Water-based paint: uses water as a solvent or dispersion medium and contains less organic solvents.
Oil-based paint: uses organic solvents (such as petroleum solvents, ketones, alcohols, etc.) as solvents or dispersion mediums and contains more organic solvents.

Environmental protection
Water-based paint: has a lower content of volatile organic compounds (VOCs), has less impact on the environment and human health, and is more environmentally friendly.
Oil-based paint: has a higher content of VOCs, has a greater impact on the environment and human health, and is less environmentally friendly.

Drying speed
Water-based paint: has a slower drying speed and takes a longer time to dry completely.
Oil-based paint: has a faster drying speed and can shorten the construction period.

Construction conditions
Water-based paint: has lower requirements for the construction environment and can be applied at lower temperatures.
Oil-based paint: has higher requirements for the construction environment and needs to be applied at higher temperatures to ensure the drying speed.
