Water-based adhesives Overview
Water-based adhesives are a type of adhesive formulation in which water serves as the primary solvent or carrier. As the name implies, these adhesives are water-based and utilize water as a propellant instead of organic volatile compounds. Water-based adhesives offer several key advantages over more traditional solvent-based adhesives.
Advantages of Water-based adhesives
Some of the main advantages of using water-based Waterborne Adhesives include:
Low VOC Emissions
One of the biggest selling points of water-based adhesives is their low volatile organic compound (VOC) emissions. Traditional solvent-based adhesives emit high levels of VOCs, which are hazardous air pollutants regulated by government agencies. Water-based adhesives contain little to no VOCs, making them more environmentally friendly and compliant with stricter emission standards.
Easy to Use
Compared to solvent-based adhesives, waterborne varieties are easier to use since they do not pose the same risks associated with flammable organic solvents. They have mild odors and are non-flammable, reducing safety hazards both during the application process and afterwards. Water-based adhesives also allow for cleanup with just soap and water.
Versatility
Water serves as an excellent adhesive medium and enables waterborne formulations to bond a wide range of materials from wood and paper to plastics, metals, and more. They can be used for applications like furniture assembly, wood flooring installation, packaging, bookbinding, and more. Water-based adhesives come in varieties suitable for everything from construction to do-it-yourself home projects.
Mechanism of Bond Formation
The bonding mechanism of water-based adhesives works similarly to other adhesive types in that it involves surface activation followed by polymerization and crosslinking. However, the solution carrier is water-based rather than organic solvents.
When first applied, water-based adhesives contain water-soluble polymers dispersed in water. As the water evaporates during drying, the polymers move closer together and begin to bond at molecular contact points through reactions like hydrogen bonding or intermolecular forces. Additional crosslinking reactions take place to form a strong three-dimensional polymer network bonded to surfaces. Compared to solvent evaporation, water evaporation from these formulations is more environmentally preferable.
Types of Waterborne Adhesives
There are several categories of water-based adhesives differentiated by their chemical composition and intended uses:
Polyvinyl Acetate (PVA)
PVA adhesives are the most widely used and utilize polyvinyl acetate as the primary resin. They are economical, versatile general purpose adhesives suitable for paper, wood, metals, and other materials. PVA emulsions form strong durable bonds yet are easy to clean up.
Polyurethane
Polyurethane water-based adhesives offer higher strength bonds than PVA varieties and are well-suited to demanding applications like automotive and construction. They have advanced heat, chemical, and weathering resistance properties. Two-part urethane formulations provide fast curing and strength development.
Acrylic
Acrylic adhesives are based on polyacrylate polymers and resins. They provide high initial tack and bonding to various non-porous substrates like plastics and metal. Formulations are available for everything from packaging to wood flooring installation.
Epoxy
Epoxy water-based adhesives have high bond strength and work well on porous and non-porous surfaces alike. They develop adhesion quickly and find use in flooring, metal bonding, automotive, and other structural applications. Two-part systems offer fast strength development.
Others
Additional specialized formulations based on polymers like ethylene vinyl acetate (EVA), styrene-butadiene rubber (SBR), and other resins deliver tailored performance properties for particular adhesive needs.
Emergence in Key Markets
With benefits of low VOCs and worker safety driving demand, water-based adhesives technology has emerged as an important alternative in several key markets:
Furniture Assembly
Most commercial furniture manufacturers have transitioned assembly operations to waterborne formulations for workplace safety and environmental compliance. They provide the strength needed for enduring bonded joints.
Wood Flooring Installation
Waterborne urethane and epoxy systems dominate commercial wood floor installation by professional contractors. They offer the workability, open time, and durable final bond quality required.
Packaging Applications
Packaging converters utilize acrylic and EVA water-based adhesives that meet FDA compliance for food-contact applications. Their non-hazardous nature streamlines production.
Building and Construction
Waterborne polyurethane and epoxy structural adhesives see growing use in flooring, metal bonding, and other construction applications where high strength is required.
Automotive Assembly
Automakers and their suppliers have moved adhesive operations to the low-VOC technologies provided by waterborne polyurethane formulations. They meet performance needs while protecting worker health.
Future Outlook
With strict global regulations curbing VOC emissions, Waterborne Adhesives technology stands poised to gain even greater market share going forward across all industries. Formulation advances will further enhance performance properties to continue broadening their applications. As environmental stewardship and sustainability remain priorities, waterborne systems provide a solution supporting both product needs and compliance imperatives.
