Allnex Crosslinkers Advance Highperformance Coatings Technology

In the pursuit of superior coating performance, the selection of crosslinkers plays a pivotal role. These specialized chemicals act as the "binders" and "reinforcers" in coating formulations, directly influencing the physical and chemical properties of the final film. As a global leader in specialty chemicals, allnex offers a range of phenolic and amino-based crosslinkers, alongside advanced acrylate monomers and modifiers, to enhance the flexibility, outdoor durability, chemical resistance, and film toughness of epoxy, polyester, acrylic, and alkyd resin systems.

Crosslinkers function by chemically reacting with resin matrices to form three-dimensional network structures, thereby imparting exceptional performance characteristics to coatings. allnex's phenolic and amino crosslinkers are meticulously designed to achieve optimal compatibility with various resin systems, striking a balance between flexibility, durability, chemical resistance, and film toughness based on specific application requirements.

To address increasingly stringent environmental regulations and further optimize coating performance, allnex has introduced innovative crosslinker technologies. For instance, the CYCAT® acid catalyst significantly accelerates the crosslinking process of low-acid polymers, particularly in low-temperature curing applications—a breakthrough with important implications for energy efficiency and production optimization. Meanwhile, the next-generation CYMEL® NF formaldehyde emission-controlled crosslinkers eliminate the formaldehyde release concerns associated with traditional amino crosslinkers, offering an ideal solution for environmentally sensitive applications such as interior decorative coatings, furniture finishes, and specialized industrial coatings where air quality standards are critical.

Beyond traditional crosslinkers, allnex demonstrates strong technical capabilities in acrylate monomers and modifiers, providing coating formulators with versatile tools to achieve specific performance targets.

This product line features a broad viscosity range (from low to high) and adjustable curing speeds. While offering excellent curing performance, these materials exhibit moderate to high shrinkage rates—a characteristic that requires consideration in precision applications or thick film coatings. Their key advantage lies in highly customizable performance through formulation adjustments.

Recognized for rapid curing speeds, high hardness, and exceptional chemical resistance, these materials are ideal for industrial protective coatings, electronic device finishes, and demanding transportation coatings where production efficiency and durability are paramount.

These versatile products allow nearly unlimited customization of performance characteristics including hardness, flexibility, yellowing resistance, and curing speed. Notably, aliphatic urethane acrylates are renowned for outstanding outdoor durability, making them essential components in exterior applications, architectural coatings, and automotive topcoats.

Primarily serving as reactive performance enhancers, these materials significantly increase curing reaction rates, reducing processing times and improving production efficiency—a critical advantage in rapid-cure applications.

Functioning as reactive diluents in non-UV curing systems, MFMAs incorporate into the polymer network during curing, minimizing viscosity while maintaining—or even enhancing—final film properties.

Widely used as reactive diluents in UV/EB curing formulations, these monomers become integral parts of the polymer matrix during curing, reducing system viscosity while contributing specific performance attributes such as hardness, flexibility, or chemical resistance.

allnex demonstrates strong commitment to sustainable development through continuous innovation in environmentally friendly coating solutions. The company maintains comprehensive technical documentation to support formulation development, including product guides for amino crosslinkers, industrial coating catalysts, and phenolic crosslinkers—each detailing application characteristics, composition information, and technical commentary for various industrial coating segments.
