Waterborne Adhesives


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 sources (e.g. hides, bones), or 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.

Select Dispersing Agents for Adhesives and Sealants

By Edward M. Petrie

Dispersing agents are essential formulation components in adhesives and sealants to effectively disperse fillers or solid particles. They provide electrostatic or steric stabilization to prevent particles from flocculating, thereby eliminate any viscosity change and phase separation. While creating a new formulation, one must choose dispersing agents with appropriate dosage level for specific product & end-user requirements. Learn more about dispersing agents by reviewing: Dispersing Agents: Mode of Action Stabilization Mechanisms Chemical Classification of Dispersing Agents Formulation Challenges Criteria for Selecting Dispersing Agents Requirements for Proper Functioning of Dispersing Agents (Continue reading or click to go on specific section of the page)

Rheology Modifiers Selection for Adhesives and Sealants

By Edward M. Petrie

Rheology modifiers improve the viscosity and have a great impact on the application characteristics of adhesive and sealant formulations. They help you to adjust the flow properties as well as prevent settling down of fillers during settling and transportation in your formulation. Explore the importance and role of rheology modifiers along with their chemistries, selection process, formulation and testing guidelines in order to easily adjust the flow characteristics of your final adhesive formulation.
