Adhesive Technology to Combat Low Surface Energy
I have discussed in a previous post on adhesive technology, low energy surfaces and the problems that they create for any self-adhesive product. A low surface energy is quite simply one in which it prevents a liquid from sufficiently wetting out and achieving a bond, the simplest example is a car being cleaned. Clean a car and water will run off conventionally, wax the car then see the difference; the water will form globules that rest on the paintwork. The globules form as the water cannot ‘wet out’ and gain purchase. All self-adhesives have a liquid base, they need to wet out to gain grip. There are many different types of low energy surfaces (LSE) but the most common are polypropylene and polyethylene. There are solutions to adhering onto an LSE, but for the most difficult, our H3510 is the ultimate solution. H3510 comes in a very small bottle, only a small amount is required, the fluid effectively changes the surface energy level allowing for a normal product to be adhered onto the substrate.
