Clariant AddWorks® IBC 251 is a dedicated additive designed for the triboelectric spraying process of powder coatings. It has high electrostatic charge loading capacity, which can significantly improve the tribocharging performance of powders. Meanwhile, it endows coatings with heat stabilization and light protection effects, providing a one-stop solution to the performance challenges in spraying, curing and weathering stages.
High electrostatic charge loading characteristic optimizes the tribocharging efficiency of powder coatings, improves the powder deposition rate and coating uniformity during spraying, and reduces the problem of missed spraying at edges and corners.
With heat protection function, it enhances the stability of powder coatings during high-temperature curing and avoids defects such as yellowing and gloss loss of coatings caused by high temperature.
Built-in light protection effect delays the aging and chalking of coatings during outdoor service, extending the service life of coatings.
Excellent compatibility with mainstream powder coating systems such as epoxy, polyester and epoxy-polyester hybrids, without affecting the core properties of coatings like adhesion and hardness.
Multifunctional integrated design eliminates the need for additional compounding of multiple additives, simplifies the powder coating formulation system, and reduces production and application costs.
Suitable for architectural aluminum profile powder coatings; by improving tribocharging performance, it ensures the coating coverage of complex parts such as profile edges, corners and grooves.
Compatible with automotive parts powder coatings, providing spraying stability and long-term weathering protection for coatings of automotive wheels, chassis parts and other components.
Applicable to household appliance powder coatings, optimizing the spraying process of refrigerator and washing machine shells, and improving the anti-yellowing ability of coatings.
Used in outdoor furniture powder coatings, balancing spraying efficiency and the performance of coatings resistant to sun and rain, extending the appearance retention period of furniture.
Suitable for powder coatings of municipal facilities such as pipelines and guardrails, solving the problems of coating weathering and protection under complex outdoor working conditions.
