“Water-based adhesive technology is a type of glue that is favorable to the environment. Water-based adhesives contain no volatile organic compounds (VOCs), making them safe for both people and the environment.”

Once the water in the formulation evaporates or absorbs into the substrate, the adhesive forms a bond between the two substrates. They're a common choice for attaching porous substrates because of this procedure.

When the water evaporates or is absorbed by the substrates, these adhesives solidify and gain strength. The substrates must be connected while the glue is still wet after it has been applied. Allowing time for some of the water to evaporate before bonding (set time) frequently improves the initial strength of the adhesive bond and allows for faster assembly. Natural and synthetic polymers that dissolve easily in water are used to make these adhesives. They harden as a result of water evaporation or absorption into the porous substrate.

They're mostly utilized in the paper industry to bond paper and paper products, as well as for moistenable adhesives like stamps, envelopes, and labels.

Types of Water-based Adhesives

Waterborne adhesives can be classified as follows

Water-based adhesives manufactured from starch or modified starch are known as starch/dextrin adhesives. They're frequently utilized in paper-related applications, such as bookbinding.
Protein/Casein Adhesives are generated from animal milk proteins. They set quickly and are commonly utilized in the food packaging sector.
Vinyl and ethylene-vinyl acetate emulsion polymers are used to make vinyl acetate adhesives. They adhere nicely to cellulose-based substrates. These emulsions, despite being bright white, dry to a transparent and flexible glue, making them perfect for bonding wood, paper, and cardboard.
Emulsified elastomers are used to make rubber latex adhesives (rubbers). These adhesives make either a strong stiff bond or a more flexible bond, depending on the formulation, and are utilized in applications such as stamp and envelope production, as well as binding fabrics and wood.
Polyacrylate emulsions age well and are resistant to a wide range of media. Acrylics based on solvents, on the other hand, are superior. Pressure-sensitive adhesives for labels and tapes, construction adhesives for tile bonding and sealing, and laminating adhesives are the most common applications.
Polyurethane emulsions and dispersions offer excellent aging characteristics and are resistant to a wide range of media. They have a high degree of flexibility and adhesion.
