Evonik Degalan M825 is a high - quality thermoplastic solid acrylic resin, designed for plastic coatings, printing inks and PVC surface treatment. Polymerized with methyl methacrylate as the base monomer, it is in the form of a bead - like suspension polymer, which can naturally physically dry to form a film after solvent volatilization, with high hardness and extremely strong adhesion to plastics and PVC
Outstanding hardness performance: The coating has high hardness after film formation, with excellent scratch and wear resistance.
Strong adhesion to substrates: Strong adhesion to plastic and PVC surfaces, the coating is not easy to fall off, suitable for surface treatment needs.
Flexible solubility: Fully soluble in various solvents such as low - boiling esters and ketones, convenient for formula preparation.
Natural self - drying film formation: Natural physical drying after solvent volatilization, no baking required, efficient construction and low cost.
Plastic coatings: Used for surface coating of various plastic products to improve coating hardness and adhesion.
Printing inks: Enhance the adhesion and stability of inks on plastic substrates.
PVC surface treatment: After PVC treatment, improve the surface coating effect and durability of PVC products.
Plastic primers: Used as special primers for plastic substrates to enhance the adhesion of subsequent coatings.
Plastic toy coatings: Suitable for surface coating of plastic toys to ensure safe and stable coating.
