The decision whether to use a 1-component (1K) or a 2- component (2K) coating system is essential in the automotive paint formulation with profound influence on application, performance and durability. Each system requires defined quality resins in order to operate successfully. At Suze, we offer a broad choice of acrylic resins specifically designed to address the different chemical needs of 1K and 2K automotive coatings so formulators can develop solutions for a variety of performance requirements.
The Simplicity of 1K Systems
One-component (1K) coatings are favored for their ease of application; they dry and cure through evaporation or cooking off a solvent. For such systems Suze presents the Thermoplastic Acrylic Resins which are providing good hardness, rapid drying and outstanding weathering resistance. These resins are suitable for use where a combination of excellent performance and easy processing is required, and present an effective solution for a wide range of automotive coat layers.
The Extra Strength of 2K Systems
The difference is that 2K coatings perform better because of a chemical reaction between its resin base and hardener. Left to their arduous duties, Suze provides hydroxyl-end acrylic resins. They are formulated to react with isocyanate hardeners to form stable, durable coatings that have a strong, flexible and permanent bond. This reaction yields a film of unsurpassed chemical resistance, mar resistance and overall durability; suitable for the harshest automotive environments.
Resin chemistry adjusts to each system
The primary difference is in the molecular structure of the resins. Our 1K systems are formulated in order that robust functionality can be achieved in a single resin system, whereas our 2K systems possess reactive functionalities for crosslinking. This key difference enables Suze to formulate specific chemical formulas, so that each resin will operate at its maximum potential in a targeted system application such as: a basecoat asking for superior appearance or clearcoat needing the absolute best protection.
Enabling Formulator Flexibility
Suze is dedicated to offering formulators choices and options. Through providing a specific series of acrylic resins for 1K and 2K technologies, we contribute to expanding the range of automotive paint products available. Our resins are a proven building block that enables manufacturers to customize their coatings for targeted performance, whether you're doing commercial vehicle refinishes or high-end OEM applications – all with a solid chemical foundation.
Conclusion
The development of one and two-part automotive topcoat formulations is highly dependent on the appropriate choice of acrylic resin with the desired chemical characteristics. Suze’s dedicated resin systems products for each of these chemistries are fundamental ingredients in the development of high performance paints that comply with today´s industry standards regarding appearance, application and long-term durability; innovative solutions for automotive surface protection.
