Dispersion Adhesives

Viscosity, solids content, open time, pressing time, and minimum film-forming temperature are among the key parameters that determine processing performance. Depending on the formulation, these adhesives can be engineered to provide rapid initial tack, short pressing times, high final bond strength, and varying levels of water and heat resistance.

Their water-based composition provides good processability with application equipment and helps reduce solvent emissions in the production environment compared with solvent-based adhesive systems. When proper surface preparation, an appropriate application amount, controlled pressing conditions, and sufficient drying are ensured, PVAc dispersion systems form durable, uniform, and high-performance adhesive bonds.

They can be formulated to provide high adhesion performance particularly on wood, wood-based panels, paper, cardboard, and other absorbent or porous substrates. They are widely used in furniture manufacturing and woodworking, solid wood bonding, lamination, veneer and foil bonding, panel manufacturing, assembly, paper converting, and packaging applications.

Viscosity, solids content, open time, drying time, activation temperature, and film-forming characteristics are among the key technical parameters that determine application and processing performance. When proper surface preparation, controlled application amount, sufficient drying, and appropriate activation conditions are maintained, PU dispersion systems form flexible, durable, and long-lasting adhesive bonds.

Thanks to their high flexibility, they can accommodate movement between materials with different mechanical and thermal properties, helping to compensate for stresses that may develop within the bonded joint. Suitable formulations can be heat-activated and engineered to provide the performance required for applications demanding high resistance to heat, moisture, plasticizers, and aging.

Depending on the formulation, they can provide high adhesion to a wide range of substrates, including wood, plastics, textiles, foams, leather, composites, and various surfacing materials. Typical applications include furniture manufacturing and woodworking, 3D lamination, foil and surface lamination, textiles, automotive interior trim, foam and upholstery applications, as well as a wide range of industrial bonding processes.

Properties such as viscosity, solids content, open time, drying time, film-forming temperature, and initial tack can be optimized to meet the requirements of different manufacturing processes. When proper surface preparation, an appropriate application amount, and controlled drying conditions are maintained, VAE dispersion systems form uniform, flexible, and reliable adhesive bonds.

Thanks to their flexible film structure, they help accommodate stresses that may develop in bonded joints subjected to folding, forming, or mechanical movement. After application, as the water is removed, the polymer particles coalesce to form a continuous and flexible adhesive film, allowing bond strength to develop.

Depending on the formulation, they can provide balanced wetting and high adhesion performance on paper, cardboard, wood, textiles, foils, and various porous or absorbent substrates. Typical applications include packaging, paper and cardboard converting, lamination, textiles, furniture manufacturing, foil bonding, and a wide range of industrial assembly applications.

Thanks to their two-component reactive chemistry, they can be formulated to provide superior performance in bonded joints requiring high resistance to water, moisture, and heat compared with conventional thermoplastic dispersion adhesive systems.

When the correct component ratio, homogeneous mixing, proper surface preparation, and controlled pressing conditions are maintained, EPI dispersion systems form high-strength, long-lasting, and reliable adhesive bonds. Mixing ratio, pot life, viscosity, open time, application amount, and pressing time are key technical parameters that determine process reliability and final bond performance.

Depending on the formulation and processing conditions, these systems can achieve high water-resistance classifications and provide reliable bond performance under varying temperature conditions. They provide high adhesion to wood and wood-based materials and are particularly suitable for bonding applications requiring high mechanical strength and resistance to environmental influences. Typical applications include solid wood lamination, window and door manufacturing, building components, panel production, and a wide range of industrial wood bonding applications.
