That being said, a wide variety of products and plastic parts in the automotive industry, as well as a wide variety of other industries also rely on polypropylene. This material is a thermoplastic polymer and belongs to the group of polyolefins. Characterized by a slipper surface, polypropylene is known for being a tricky surface for inks to properly stick to. For instance, even gluing polypropylene together can pose as an exhausting endeavor.

The PN Series Pad Printing ink was specially formulated to decorate these products and to provide excellent adhesion to most polypropylene-based substrates. Often, a product will not be 100% polypropylene which will require the substrate to undergo pre-treatment. However, if the substrate is pure polypropylene enjoy excellent adhesion due to the composition of PN series ink. To get started, PN is best known for:

  • Exceptional adhesion to polypropylene products

  • Extended pot life when used as a 2-component ink
