Non-slip coatings are becoming increasingly familiar. They are used everywhere from floors to packaging. However, it can be difficult to know exactly how much non-slip coating to use for different substrates and surfaces. Here’s a quick guide.
What are non-slip coatings?
Non-slip coatings can be applied to many different products. Many of your floors will have non-slip finishes, but this treatment is also widely used on pallets in the shipping industry.
Non-slip coatings are also applied to the paper and cardboard that covers many of the surfaces found in public transport. Invisible, effective, and guaranteed to stick, the coating creates a surface that reduces the vulnerabilities traditionally created by water, detergents, angles, and vibrations.
How do non-slip coatings work?
Most non-slip coatings create a textured surface which increases friction. Slip-resistance is measured by pendulum tests, ramp tests, and micro-roughness testing. Micro-roughness testing aims to establish whether or not a surface can break through various contaminants, while the other tests mimic actions such as movement or walking in order to determine how well a surface resists slippage.
This basic principle can be extended to any substrate. However, as all materials have slightly different physical and mechanical properties, they often need different anti-slip treatments. This means that the application needs to be carefully measured and controlled. Good anti-slip treatments offer good return on investment (ROI) by combining low grams per square metre (gsm) with excellent micro-roughness.
How much non-slip coating should I apply?
If you are using a product such as the popular FP 2177, it’s good news. Whether you are applying it to paper, cardboard, or other substrates, it offers a highly efficient coating. The amount of anti-slip adhesive you need depends entirely on the porosity of the substrate. For very porous substrates such as cardboard, a dry coating weight of 8gsm is required. For non-porous substrates, 5gsm is sufficient for excellent results. This must be dried above 95oC, which can be achieved with a hot air wind tunnel, infra-red, or ecologically friendly UV drying. Due to its unique tactile qualities, FP 2177 is often used for packaging. In this case, either gravure or anilox rollers are ideal for application.
