Polyaspartic Resins

Polyaspartic Resins As industry and product diversity have grown, there has emerged a need for materials that create protective coatings on materials in use. In response to this need, materials produced with advancing technology have also evolved and diversified. Polyurethane coating technology dates back to the 1970s and its application areas continue to expand to the present day. This coating provides advantages in the coating industry through rapid curing, reaction time, surface adhesion performance, high film formation and solvent-free composition. Although polyurethanes can be readily synthesized through addition reactions of isocyanates and amines, the rapid nature of the reactions they produce requires special equipment and working parameters [1, 2]. For this reason, work has been carried out to develop this promising product in the coating sector. Polyaspartic esters, which form the basis of polyaspartic resins, are referred to as chain extenders or secondary diamines. Moreover, they are produced through Michael addition reactions between long-chain diamines and maleate (Figure 1). Furthermore, these resins can subsequently react with isocyanates [3, 4]. Today, polyaspartic ester polyurethane (aliphatic polyurethane) production and use has enabled these resins to find application in virtually every area of the coating industry owing to their high mechanical properties, corrosion prevention, solvent-free nature, high UV resistance, weatherability, excellent adhesion and flexibility characteristics (Figure 2) [1, 3, 5, 6]. Additionally, polyaspartic resins are referred to as next-generation aliphatic polyurethanes. This two-component polyaspartic product is manufactured using polymerization methods.

Polyaspartic product synthesis reaction.[/caption] Polyaspartic resins developed in İzel Kimya's advanced technology research and development laboratories are: IZASP 14, IZASP 15, IZASP 151 and IZASP 285. Of these products, IZASP 151, obtained by thinning IZASP 15 with solvent, is the only polyaspartic resin containing solvent. The properties of the manufactured resins are presented in Table 1. Table 1. Polyaspartic resins and their properties. These polyaspartic resins are generally used in exterior facade coatings, swimming pools and furniture, roofs and garages, wind power plants, interior and exterior pipe coatings, industrial coatings, aircraft hangars, shopping centers, hospitals and airport flooring. In addition to these applications, polyaspartic resins are highly preferred resin types owing to the aforementioned advantages as well as their easy application and long pot life.
