Evonik Degussa Degalan PM381N is a high-quality solid acrylic resin, designed for various air - drying solvent - based coatings and inks. Copolymerized with n - butyl methacrylate and MMA as base monomers, it is in the form of a ground bulk polymer, featuring fast air - drying and excellent solubility, which can be completely dissolved in low - boiling esters, ketones and glycol ethers, providing stable film - forming effect for coatings and suitable for multi - substrate painting needs.
Efficient air - drying film formation: It can achieve rapid drying by solvent volatilization without additional baking, improving construction efficiency.
Excellent solubility: It has good compatibility with low - boiling esters, ketones and glycol ethers, with a smooth dissolution process, facilitating formula preparation.
Strong substrate adhesion: It has good adhesion to various materials such as PVC copolymers, PS, PC, PMMA, ABS, as well as metals, masonry and other substrates.
Stable and reliable performance: It has a uniform molecular weight distribution, and the film formed has excellent light resistance and chemical resistance, ensuring the long - term use effect of the coating.
Aerosol paint: Suitable for various aerosol can spraying products, with fast film formation and good color stability.
Marine and container coatings: Resistant to marine environment corrosion, providing long - term protection for metal substrates.
Impregnating and penetrating primers: Used for metals, masonry and other substrates to improve the adhesion and corrosion resistance of subsequent coatings.
Printing inks: Adaptable to various printing processes, enhancing the adhesion and weather resistance of inks.
