Fortunately, POR-15 has come to the rescue with a corrosion-fighting line of rust preventive paints. While typical paints are weakened by moisture, POR-15 uses a unique formula of polymeric isocyanate derivatives that are strengthened when exposed to moisture. This allows the POR-15 to develop a long-lasting, non-porous, chip- and crack-resistant coating that keeps moisture and chemicals out.
But wait, students — there’s more science involved.
The dense, cross-linked molecular structure of POR-15 also allows it to bond chemically to rusted metal by penetrating the surface. POR-15 calls this “polydigital adhesion,” and you can see how it works in the photo below. This allows POR-15 to not only cover up rust and prevent it from spreading, but also strengthen the underlying metal and seal holes by forming its own membranes.
POR-15 coating options include:
- POR-15 Black: ideal for frames, floorboards, trunks, and engine compartments
- POR-15 Silver: contains metal filler and should be used on badly rusted steel to fill small holes
- POR-15 Clear: for touch-up on exteriors surfaces before painting
You don’t need a chemistry degree to properly apply POR-15 rust preventive coatings. Unlike dual-stage coatings, POR-15 requires no catalyst. It’s typically applied with a roller and can even be top-coated by using the proper primer.
POR-15 has created a 3-step application process using:
