Polyvinyl butyral (PVB) is a special polymer with a wide range of applications. It can be found in many different paints, coatings and adhesives.
Thanks to its many useful properties, it can act as a binder for coatings, primers, metal powder or ceramic as well as an interlayer film in laminated safety glass.
Featuring excellent
adhesion and film-forming properties, polyvinyl butyral has already
established itself as an essential chemical in the industry. With
an international network of reliable manufacturers, we a
trusted supplier and distributor of a wide range of
high-performance polymers, resins and other specialty chemicals for
applications such as coatings, printing, adhesives and
laminated safety glass.
Polyvinyl butyral, CAS No. *********2, is a synthetic polymer
that is part of the polyvinyl acetal family. It is manufactured and
processed using thermoplastic methods. That is why it appears as a
fine, free-flowing white powder. The properties of polyvinyl
butyral resins vary according to their degree of acetylation and
molecular weight.
Their strength and elasticity depend on their molecular weight, for
example. In contrast, their water absorption capacity and
solubility in non-polar solvents are determined by their degree of
acetylation. Nevertheless, in general, polyvinyl butyral resins are
highly compatible with organic solvents and other polymers.
All types of polyvinyl butyral have a few things in common: They
can dissolve in almost all organic solvents and are compatible with
plasticizers and other resins. Furthermore, they have good light
resistance and are heat-sealable at temperatures in excess of **0
degrees Celsius.
The related benefits of polyvinyl butyral at a glance:
These properties
make the chemical a popular binder and hot-melt adhesive in many
applications.
Polyvinyl butyrals offer excellent properties in the following applications:
One major application of polyvinyl butyral is as a hot-melt adhesive to bind glass panels together for use in windows and other applications. Due to its extremely high tensile strength and ability to bind glass splinters, polyvinyl butyral is commonly used as an interlayer film in laminated safety glass.
For instance, the polymer layer between the glass panels of a windshield is made of polyvinyl butyral most of the time.
Because this compound is able to adhere very well to glass, it is perfect for bonding glass panels together or to other materials. Polyvinyl butyral can be applied as a solution or in a molten state.
The manufacture of laminated glass involves bonding sheets of glass
together using polyvinyl butyral resin, plasticizers and other
substances. This process takes place under high heat and
pressure.
Polyvinyl butyral resins are also commonly used as binders in inks, paints and primers. Regardless of the application, polyvinyl butyral is able to adhere exceptionally well to virtually any materials due to its excellent bonding properties.
Their optical clarity and excellent adhesive and film-forming properties make polyvinyl butyral resins a truly versatile ingredient in adhesion primers, anti-corrosion primers, stove enamel and glazes.
