Coatings generally consist of four basic components: film-forming substances (resin, lotion), pigments (including constitutional pigments), solvents and additives (additives). It can be seen that resin and lotion are film-forming substances of coatings. What is the difference between resin and paint emulsion?
Difference between paint emulsion and resin
1.Paint emulsion and resin – different definitions
The Paint emulsion is made by adding surfactant to insoluble solution polymer, and lotion of the polymer is produced under high-speed stirring.
Resins usually refer to organic polymers that have softening or melting range after being heated and tend to flow under the action of external forces during softening. They are solid, semi-solid or sometimes liquid at normal temperature.
Paint emulsion and resin – different functions
The Paint emulsion has permanent flexibility, good acid and alkali resistance, and can be mixed with most additives. The Paint emulsion can form a transparent film at a certain temperature, which is called the minimum film forming temperature. The film has a good barrier to water drops.
Resins are generally insoluble in water and soluble in organic solvents. They are solid, medium-solid, pseudo-solid at room temperature, and sometimes liquid organic substances. It has a softening or melting temperature range, has a tendency to flow under the action of external forces, and is often shell-like. It has good comprehensive physical and mechanical properties and is easy to be processed. The disadvantage is poor weather resistance, heat resistance and flammability.
Paint emulsion and resin – different application scope
1. Paint emulsion has a wide range of bonding properties. In addition to bonding wood, leather, fabric, paper, cement, concrete, aluminum foil, galvanized steel plate and other materials, it can be used as interior and exterior wall coatings, roof waterproof coatings, fire retardant coatings, and anti rust coatings.
2. The resin is mainly used as engineering materials and household appliances. It is applicable to household electrical products, such as television shells, refrigerator linings, vacuum cleaners, and plastic products for instruments, telephones, and automotive industries.
