Hot Melt Adhesive Manufacturers - What Is Water-based Adhesive
Water-based adhesives are not as popular as hot melts, but they are useful in a wide variety of applications and are a reliable choice.
Water-based (or more commonly referred to as waterborne) adhesives are typically formulated from either: 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)
Two of the more popular types of water-based adhesives are EVA/PVA and Vegetable-based (Dextrin).
Dextrin is commonly used for paper applications and contains a starch base, which allows the adhesive to have a more flexible, solid bond.
EVA/PVA polymers are water-based emulsions. These are the ‘work horses’ of water based adhesives and are commonly used to bind fabrics, woods, papers, foams and some plastics.
Similar to hot melt adhesives, water-based glues are used for many similar applications. The decision to use one or the other usually comes down to bond requirements, equipment type and required production speeds.
