Plastic repellent paint

The plastic repellent paint is an innovative product developed by Slice Engineering, a company known for manufacturing the high performance Mosquito and Copperhead hotends.

It is an aqueous paint based on a nanosuspension of Teflon particles that can be applied to any metallic surface. When dry, it forms a solid, transparent layer of PTFE that prevents molten plastic residues from adhering to the surface.

The importance of keeping the nozzle and heating block clean is not only due to aesthetic issues. When plastic melts accumulate on the outside of the nozzle and heater block, they can be dislodged during printing and become deposited on the surface of the part, damaging the part's finish.

This product has been formulated to achieve an excellent bond with the metal, considerably increasing its durability. It can also withstand temperatures of up to 290ºC, which is sufficient for the most common materials.

Slice Engineering's non-stick paint comes in a 3 mL can with a convenient brush applicator. It is as easy to use as applying a layer with the brush on the surface of the components when they are at room temperature and heating the hotend up to 150 ºC to evaporate the water and achieve the solid coating.
