Paints and varnishes containing polymers

In this article, we'll discuss polymers in paints and varnishes, information on which is based on materials from the website domioffis.com. If you're interested in more detailed information, we recommend visiting it. For now, let's talk briefly about polymers.

Polymer film-forming components are the main constituents of liquid and paste paints and varnishes. Depending on the requirements, paints can be based on either high-molecular or low-molecular synthetic or natural polymers. They are also further divided into the following categories: non-convertible, convertible, and mixed. As you can see, there's enough information for an entire scientific dissertation, so we'll repeat and say that more detailed information can be found on the website.

These days, polymers play a key role in construction. No construction project can be completed without paint and varnish coatings. And our polymer has found its application here. Convertible film-forming polymers include phenolic, oil-based, epoxy, alkyd, rubber, organosilicon, polyurethane, acrylic, and other polymers that form insoluble and non-fusible elements as a result of chemical processes.

Non-convertible film-forming polymers include nitrocellulose, acrylic, fluoroplastic, organosilicon, perchlorovinyl, and other resins that retain their thermoplasticity and solubility even after the solvent is removed. Mixed film-forming polymers include the polymers listed above.

After applying a paint coating to the surface being painted, a film forms on the product that performs its primary function – protecting the metal product from corrosion. In addition to protecting metal products, paints and varnishes also protect non-metallic materials. Based on their intended purpose, they are classified as putties, primers, varnishes, and paints. Putties are varnishes with a high film-forming polymer content and are used to smooth surfaces.

Primers are varnishes with a pigmented film-forming polymer content and are used to increase the adhesion of the painted surface to subsequent layers of paint. Varnishes contain dissolved film-forming polymers and are used to create a transparent protective layer. Paints are varnishes with a less pigmented film-forming polymer content than primers. They serve as a finishing agent and simultaneously provide protection from harmful conditions.
