Organosol vs. Plastisol — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on May 9, 2024
Organosols are dispersions of polymer in an organic solvent, used in coatings and adhesives, while plastisols are dispersions of PVC particles in a plasticizer, often used for flexible coatings and moldings.

Key Differences
Organosols consist of polymers dissolved in organic solvents. These solvents evaporate upon curing, leaving behind a solid polymer film, which makes organosols useful in coatings and adhesives. On the other hand, plastisols are made from PVC particles suspended in plasticizers, which provide flexibility and require heat curing.
Organosols are typically more fluid due to the solvent content, leading to thin, smooth coatings. Conversely, plastisols are thicker, allowing them to form more substantial layers ideal for molding and dipping.
Organosols contain volatile organic compounds (VOCs), which contribute to environmental concerns during application. In contrast, plastisols contain fewer VOCs, making them preferable for applications where environmental impact is a priority.
Organosols offer good adhesion to various substrates, useful in applications requiring strong bonds. However, plastisols adhere well to non-porous surfaces like metals and glass, especially after heat curing.
Organosols can handle a range of temperatures and are chemically resistant, while plastisols excel in providing flexibility and impact resistance once cured.

Plastisol
A plastisol is a colloidal dispension of small polymer particles, usually polyvinyl chloride (PVC), in a liquid plasticizer. When heated to around 180 °C (356 °F), the plastic particles absorb the plasticizer, causing them to swell and fuse together forming a viscous gel.
Organosol
A sol (colloid) comprising solid particles in an organic continuous medium.
Plastisol
A liquid dispersion of plastic or resin that may be converted to a solid by heating
Common Curiosities

Are organosols suitable for outdoor use?
Organosols can be suitable for outdoor use if formulated for weather resistance.
Do organosols contain solvents?
Yes, organosols contain organic solvents that evaporate during curing, leaving behind a solid polymer film.
How thick are organosol coatings?
Organosol coatings are generally thin due to the fluid nature of the solution.
Do plastisols offer impact resistance?
Yes, plastisols form a flexible layer that provides good impact resistance after curing.
What is an organosol used for?
