Low Viscosity Solvent Based Acrylic Resin Good Compatibility With CPP Resin

Achieving strong adhesion to low-surface-energy plastics such as polypropylene (PP) and polyethylene (PE) remains a significant challenge in modern coating systems. Chlorinated polypropylene (CPP) resins have long been used as tackifying resins due to their excellent affinity for polyolefin substrates. However, while CPP exhibits excellent bond strength, it typically lacks hardness, gloss, and long-term weatherability. Therefore, acrylic resins with excellent compatibility with CPP play a key role, combining the strengths of both materials to deliver superior coating performance.

Acrylic resins are highly valued for their high clarity, gloss, hardness, chemical resistance, and weatherability. When acrylic resins blended with CPP resins, their good compatibility ensures uniform dispersion and formulation stability. Acrylic resins enhance the coating's mechanical strength, surface durability, and aging resistance, while CPP provides excellent adhesion, flexibility, and impact resistance on challenging plastic substrates. This synergistic effect creates a coating that is not only tough and durable, but also maintains long-term performance despite outdoor exposure and chemical attack.

Product Description

SA-533 is a low viscosity and low acid value thermoplastic acrylic resin primarily composed of MMA and n-BMA polymers. SA-533 exhibits excellent adhesion, alcohol solubility, weatherability, distinctness of image, and compatibility with CPP resins. Solvent based acrylic resin SA-533's excellent compatibility with CPP resins provides a powerful solution for coatings and inks that have difficulty adhering to substrates. By leveraging the adhesion-promoting properties of CPP with the durability and weatherability of acrylic, formulators can develop high-performance coatings that meet the demanding requirements of environmentally friendly coatings, plastic coatings, screen printing inks, and industrial applications. This compatibility not only enhances coating performance but also broadens the application range of both resins, making them an indispensable component of advanced coatings technology.
