Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are among the most widely used additives in the plastic industry. They are also usually cheaper than other additives used in polymer processing. Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of products. Examples include:
Plasticizers in Paint & Coatings: Uses, Types and Selection
Plasticizers are additives that increase the elasticity of coatings based on film-forming materials. In order to meet specific demands for your application, proper film-formation is essential. But, selecting the right plasticizer with a unique property of your choice is sometimes challenging.

Home Brands Eastman plasticizers Markets & Applications Coatings Coatings Eastman plasticizers help maintain proper flow properties and improve film formation and weatherability in coatings. They work by reducing film formation temperature, elasticizing coatings, and lowering the Tg of polymers.
Flexibility of Paints and Coatings: Factors and Test Methods
The standard flexural strength test for materials, including coatings, paints and films, is ASTM D790. The different varieties of this test include three-point and four-point methods. For ASTM D790, the pressure is applied to the central region of a bendable sample. The test is stopped when the specimen reaches 5% deflection or the specimen
SpecialChem - Plasticizers in Paint & Coatings - Uses, Types
Plasticizers are used in coating formulations (for instance in NC lacquers) for the following purposes: To enable proper film formation To improve film appearance & gloss To improve mechanical film properties, such as adhesive strength, flexibility & elongation To increase resistance to light, heat, sudden temperature changes (cold-check test)
- What are plasticizers used for?
- Plasticizers are additives that increase the plasticity or fluidity of a material. Coating formulations based on physically drying binders such as nitrocellulose, require external plasticizers for optimal film formation. They are used to control the film formation process of coatings based on physically drying film-forming materials.
- What are the different types of plasticizers used in the paint industry?
- There are various types of plasticizers used in the paint industry, each offering unique benefits depending on the application requirements. The two primary categories of plasticizers are phthalates and bio-based plasticizers. Phthalates are the most common type of plasticizers.
- Why are plasticizers important in paint & coatings industry?
- Plasticizers are indispensable in the paint and coatings industry, providing the necessary flexibility, durability, and workability for a wide range of applications.
- Can plasticizers be used in coating formulations?
- For natural products or hard polymers of poor processing, the option is the external use of plasticizers in the coating formulations. Plasticizers interact physically with the polymer binder molecule, without a chemical reaction and form a homogeneous system.
- Which plasticizers are used in coatings?
- Commonly used plasticizers in coatings are: DINCH (dicarboxylate) and more. Plasticizers may be solvents or non-solvents to the binder. For example, NC is soluble in plasticizers such as di-butyl phthalate (DBP), di-iso-octyl phthalate (DIOP), di-octyl phthalate (DOP) & tricresyl phosphate.
- How do plasticizers affect the physical properties of paint?
- Plasticizers significantly impact the physical properties of paint. By reducing the glass transition temperature, plasticizers make the paint more flexible and easier to apply. This flexibility is crucial for various applications, including wall coverings, where the paint needs to adhere smoothly and evenly to different surfaces.
