Usage Instructions: Preparation: Ensure the 3D printer nozzle and hot end surface are fully cooled, then thoroughly clean them. Application: Shake the plastic protection coating well, then use the built-in brush to evenly apply a thin layer to the prepared surfaces. Curing: Let it stand for 3-5 minutes, then heat to the working temperature to form a durable, transparent protective film (high adhesion, heat-resistant). Maintenance: After printing, clean the nozzle surface and reapply a fresh layer for immediate readiness in the next use. Multi-functional Coating: This milky white, water-based fluoropolymer solution is ideal for coating glass fibers, aramid fibers, and other materials. It provides superior wetting and film-forming properties and can coat low surface energy substrates like PTFE, offering excellent filament resistance. Outstanding Stickiness and Hydrophobicity: The surface has excellent stickiness resistance, reducing dirt accumulation, and offers exceptional hydrophobic and oleophobic performance. It is highly effective in high-temperature and harsh environments, ensuring nozzle cleanliness and preventing issues during printing. Enhanced Print Quality: The PTFE protective coating, a water-based solution, repels plastic and prevents nozzle build-up, improving print quality. It ensures clearer, more precise 3D prints while reducing the need for maintenance, offering excellent value for money. High Temperature : With a wide temperature range from -200°C to 290°C, the PTFE protective coating offers excellent stability, extending the lifespan of the coating and enhancing overall performance during prolonged use.Compatible with common 3D printing materials such as PLA, PETG, ABS, TPU.
