Plasticizers - Coatings Ingredients Selection
Plasticizers lower the Tg of the resin and elasticize the coating. When added to a coating formulation, plasticizers improve film formation and gloss, increase the resistance of a coating to heat and light and enhance mechanical properties like adhesion, elongation etc. Plasticizers are widely employed in industrial and automotive applications
Plasticizers: Types, Uses, Classification, Selection & Regulation
A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Selection of Plasticizers for Coating Formulations
For example, NC is soluble in plasticizers such as di-butyl phthalate (DBP), di-iso-octyl phthalate (DIOP), di-octyl phthalate (DOP) & tricresyl phosphate. However, NC is insoluble in plasticizers like main stearates and oleates. Main external plasticizers are low molecular weight materials, demonstrating fast interaction with the polymer chain.

- What is the function of plasticizer?
- We define plasticizer as an inert low volatility solvent of a molecular weight at least 300, which incorporated in a plastic (PVC) or synthetic rubber, increases their flexibility, elasticity and handling. The function of plasticizers is to reduce the intensity of bonds among the polymer molecules.
- Is polyvinyl chloride a base plasticizer?
- If the polymer is soluble in the plasticizer, it is called a base plasticizer. Polyvinyl chloride (PVC) is the second pure polymer after polyethylene in the European market. Although polymer as a pure resin has poor applications and requires the use of additives to produce products of acceptable quality.
- What is the function of plasticizers in PVC?
- The function of plasticizers is to reduce the intensity of bonds among the polymer molecules. These bonds, or attractions between molecules (Van de Waals forces), give a large rigidity to PVC. The first plasticizer that was used was Dioctyl Phthalate (DOP) and all the studies were made from here.
