Product Description
BK7 is a resin-free high-transparency nano color paste from DENSON's NA series, featuring P.Bk.7 pigment dispersed to an ultra-fine 90-150nm particle size in PMA carrier. Carbon black, nano transparent black, high heat 280°C, halogen-free. The 100% resin-free formula ensures no interference with resin structure or curing.
Unlike dye-based color concentrates that inevitably migrate and stain, NA nano pigments remain permanently locked in place with zero migration. With light fastness grade 8+ and heat resistance of 280°C, this grade delivers outdoor durability over 5 years with no discoloration.
Ideal for optoelectronic functional films, electronic packaging, automotive topcoats, precision inks, functional plastics and luxury leather recoloring. Halogen status: Halogen-Free (ND).
