Polyvinyl adhesive application systems are widely used in many industrial and commercial applications. They are commonly found in packaging, construction, automotive, and woodworking industries, to name a few. The demand for high-performing adhesive solutions has led to the development of new materials, additives, and technologies. Selvol polyvinyl alcohols, for instance, offer superior performance as additives and modifiers in polyvinyl acetate emulsion-based sole or compounding adhesives.
What is Polyvinyl Acetate Emulsion-Based Adhesive?
Polyvinyl acetate (PVA or PVAc) emulsion-based adhesive is a water-based, non-toxic, and easy-to-clean adhesive that is widely used in various applications. It is made by emulsifying polyvinyl acetate resin in water, along with other additives such as plasticizers, fillers, and stabilizers. The emulsion-based adhesive can be applied on different substrates such as wood, paper, textiles, plastics, and metals.
One of the main advantages of PVA emulsion-based adhesive is that it dries clear and forms a strong bond. It is also easy to use, quick-drying, and provides excellent adhesion on porous surfaces. However, the adhesive may have some limitations when it comes to specific applications, such as high-temperature resistance or low water resistance.
Why Selvol Polyvinyl Alcohols Are Ideal Additives Solutions and Modifiers?
Selvol Polyvinyl Alcohols are a range of water-soluble, synthetic polymers that are widely used in various industries. They are commonly used as additives and modifiers in adhesives, coatings, packaging, and textiles. Selvol PVOHs have unique properties that make them ideal additives for polyvinyl acetate emulsion-based adhesive.
Selvol PVOHs are highly compatible with polyvinyl acetate emulsion and help to improve the performance of the adhesive. They act as a barrier coating, which enhances the adhesion by preventing the penetration of the adhesive into the substrate. Selvol PVOHs also improve the viscosity and cohesive strength of the adhesive, which leads to a stronger bond.
Selvol PVOHs offer several benefits as additives solutions and modifiers in polyvinyl acetate emulsion-based adhesive, such as:
Improved water resistance: Selvol PVOHs can significantly improve the water resistance of the adhesive. They form a barrier layer that prevents the penetration of water into the adhesive, which ultimately provides a long-lasting and reliable bond.
Improved adhesion: Selvol PVOHs improve the adhesion of the adhesive by enhancing its viscosity and cohesive strength. This leads to a stronger and more durable bond on a variety of substrates.
Improved heat resistance: Selvol PVOHs can enhance the heat resistance of the adhesive by increasing the glass transition temperature (Tg) of the adhesive. This enables the adhesive to withstand higher temperatures without compromising its strength.
Improved flexibility: Selvol PVOHs can improve the flexibility of the adhesive by reducing its brittleness. This makes the adhesive more pliable, which enables it to mold to the shape of the substrate.
Conclusion
Selvol Polyvinyl Alcohols offer better additives solutions and modifiers in polyvinyl acetate emulsion-based adhesive. They provide improved water resistance, adhesion, heat resistance, and flexibility. Selvol PVOHs are ideal for a variety of applications, including packaging, woodworking, automotive, and construction. By incorporating Selvol PVOHs into your adhesive formulations, you can achieve superior performance, durability, and reliability.
