Evonik (formerly Degussa) P24 is a beaded bulk polymer resin based on n-butyl methacrylate, designed for solvent-evaporative self-drying coatings, high-end printing inks and compliant heat-sealing varnishes. This solid beaded resin has excellent broad-spectrum solubility, forming dense and transparent film with reliable self-drying performance, meeting food contact related regulatory requirements.
Efficient self-drying property - Self-drying upon solvent evaporation, no additional curing conditions required, greatly shortening construction cycle and improving production efficiency.
Broad-spectrum solubility - Easily soluble in various solvents such as aromatics and esters, flexible formulation, suitable for different construction needs.
Food compliance guarantee - Meets food contact regulatory requirements, applicable to heat-sealing varnishes related to food packaging, safe and reliable to use.
Food-grade heat-sealing varnishes: Surface coatings for food packaging, stable heat-sealing performance, meeting food contact safety standards.
Ceramic/glass transfer varnishes: Transfer coatings for ceramic utensils and glass products, high transfer clarity, film wear-resistant and washable.
High-end printing inks: Printing on plastic films and paper packaging, firm adhesion and weather resistance, suitable for high-speed printing line requirements.
Electroplating isolation coatings: Isolation coatings for metal components before electroplating, preventing electroplating solution erosion, ensuring electroplating precision and adhesion.
