Adhesives
Adhesive formulations combine binders, reactive components, fillers, additives, and other specialty materials to create bonds suited to specific substrates, processing methods, and service conditions. Lintech supplies raw materials used across a variety of adhesive technologies, including systems designed for structural, flexible, waterborne, hot-melt, and other bonding applications.
Why It Matters
Adhesive performance depends on both the bond and the formulation behind it
An adhesive must form sufficient contact with the substrate, develop cohesive strength within the adhesive layer, and maintain that bond under the conditions it encounters in service. Depending on the application, important considerations can include flexibility, cure behavior, working time, viscosity, heat resistance, moisture resistance, chemical resistance, and long-term durability.
Formulation ingredients can affect each stage of that process. The chemistry of the binder helps establish the basic character of the adhesive, while other components can influence cure, tack, wetting, flow, rheology, reinforcement, stability, and interaction with the substrate.
Lintech supplies a broad range of specialty raw materials used in adhesive and sealant formulations, providing access to technologies from established suppliers for both formulation development and ongoing production.
