There has recently been a strong inclination in the industry towards using so-called "green" materials. This trend has forced the industry to seek renewable materials with the least environmental impact. Polyvinyl acetate (PVA) is a thermoplastic polymer that has attracted significant attention over the years as a raw material for the adhesive industry. This polymer shows a wide range of varieties, whether modified or unmodified, in solution or emulsion form, and as a homopolymer or copolymer. For this reason, it is a suitable material for bonding a wide range of materials. PVA adhesives, also known as liquid or white glue, are based on polyvinyl acetate resins, are environmentally friendly, and have diverse applications.

Polyvinyl acetate resin is created by the polymerization of vinyl acetate by immersion in water, which results in a milky white emulsion that forms a transparent film after drying. This resin, along with other additives, is used as an adhesive in various industries to improve product performance and increase its useful life. In general, a PVA-based adhesive is a water-soluble adhesive produced through a series of reactions by combining vinyl acetate as the main ingredient with a certain amount of other raw materials to improve product performance and increase its useful life. The properties of such adhesives are largely influenced by the molecular weight and the compatibility of the vinyl acetate with other compounds. Adhesion strength and moisture sensitivity depend on the amount and type of colloid and other functional additives such as wetting agents and plasticizers.

The most important advantages of PVA adhesives are their economical price and wide range of applications. These adhesives can be very flexible while maintaining a strong bond, which is used for bonding and creating adhesion to polar and porous surfaces, including the construction, wood, textile, paper, and cardboard industries, as well as some parts of the leather industry. The properties of the adhesives can be modified or adjusted by adding several compounds. The inclusion of tackifiers, adhesion promoters, and fillers in adhesives is usually done to change the adhesive's performance for specific applications. Due to its flexible structure and a large number of acetate groups, polyvinyl acetate can form many hydrogen bonds with wood for better surface adhesion. Polyvinyl acetate is used in packaging and as an adhesive for porous materials such as paper and wood. One of the reasons for its tendency to adhere is the presence of polar acetate groups in the polymer molecules. One of the most important types of polyvinyl acetate adhesives is white glue or wood glue. Water-based polyvinyl acetate adhesives are widely used in bonding wood and paper products. These adhesives can be easily stored at room temperature, are easy to use, and are cost-effective.

These adhesives produce a transparent and hard film that has good weather resistance and withstands water, grease, oil, and petroleum fuels. Other features include high initial tack, an almost invisible bond line, softening at 30 to 45 °C, good resistance to biodegradation, poor resistance to creep under load, and low cost. PVA adhesives and copolymers are also used as hot-melt adhesives, sealants, and in textile finishing, wood plastic, and inks.

For years, Iran Industrial Resins Co., as a producer of polyvinyl acetate-based adhesives in the country, has been seeking to meet the needs of the industry. The adhesives from this industrial group, with their desirable properties and hardness, are used in various industries as follows:
