What Are the Different Types of Water Based Adhesive?

Water based adhesive glue that is categorized in one of the following four categories: vegetable glues, resin cements, animal or protein glues, and latex cements. Each of the different types has its own characteristics. Depending on the formulation, the adhesive can result in a hard resin finish or a tacky filmy finish. In general, a water based adhesive is solvent free, making it safe to use in close quarters and areas that may not be well ventilated, such as classrooms. The most popular water based adhesive is white glue or wood glue.

Vegetable glue is a common type of water based adhesive. These glues have a starch base and a brittle finish. Commonly used to bind books, this water based adhesive has a brown color and a reputation as a durable, long-term bond for paper. The vegetable based adhesive is more likely to break down when exposed to water.

Another water based adhesive is resin cement. Resin cements are emulsions, mixes of liquids that cannot be blended. With resin cements, polymers such as ethelyne vinyl acetate (EVA) or polyvinyl acetate (PVA) are emulsified and placed in water, which acts as a carrier. While resin cements are white when wet, they dry clear and are relatively flexible. Resin cements are useful for bonding some plastics, paper, and wood.

Waterbased Adhesives Technology Review
As part of an overall project to provide industry representatives, researchers, technical assistance providers, research funders, and others with better access to information on pollution prevention research, the Pacific Northwest Pollution Prevention Resource Center (PPRC) undertook literature reviews on alternative solvent-free adhesive technologies that have the potential to replace conventional ozone-depleting and solvent-based adhesive systems. A set of three technology reviews covering hot melt adhesives, radiant-cure adhesives, and waterbased adhesives was prepared from the literature research.

Water-based (or more commonly referred to as waterborne) adhesives are typically formulated from either:
  1. Natural Polymers – from vegetable sources (e.g. dextrins, starches), protein sources (e.g. casein, blood, fish, soybean, milk albumen), and animal (e.g. hides, bones), or
  2. Soluble Synthetic Polymers – from polymers including: polyvinyl alcohol, cellulose ethers, methylcellulose, carboxymethylcellulose, and polyvinylpyrrolidone
These adhesives may be supplied as solutions or formulated as dry powders which must be mixed with water prior to application. The strength of the adhesive is attained when water is lost from the glue line by evaporation or absorption by the substrate. Because of this requirement, use of these adhesives requires that at least one substrate is permeable. Where neither substrate is permeable, it is possible to apply a thin coat of adhesive, allow it to dry, and then activate the adhesive by lightly wiping with a wet brush or roller or spraying with water. This gives the system “quick tack” and the amount of water in the glue line is so small that a porous substrate is not required. Because the polymers are water soluble, bonds made using these adhesives have limited resistance to moisture and water. Some plant glues and the casein glues have the special feature that the base raw materials are insoluble in room temperature water and have to be dissolved in alkaline media (sodium hydroxide solution or ammonia). These adhesives have improved moisture resistance compared to adhesives that are directly soluble in water. Many water-based solution adhesives are perishable and so extended storage is not possible.
