Applying Corrosion Resistant Coatings

In the world of protective coatings, combating corrosion is a significant challenge. Corrosion resistant coatings are essential in extending the life and maintaining the integrity of various materials, especially metals. At Marcote, we utilise two primary methods for applying corrosion-resistant coatings: physical barriers and galvanic layers. Here’s a closer look at these two methods. Physical Barrier Coatings The first method involves creating a physical barrier between the material and the corrosive environment. This barrier is typically a non-porous or non-permeable layer that prevents corrosive agents – like water in the case of atmospheric corrosion – from penetrating and reaching the

The Materials Behind Abrasion Resistant Coatings

Abrasion resistant coatings primarily act as a physical barrier to protect machinery components and increase their longevity, however, our coating systems can be given additional properties such as low-friction, non-stick, or greater traction – further enhancing your bespoke desired performance. But what are the materials behind these useful properties? Read on to find out. Tungsten Carbide for Abrasion Resistance Tungsten carbide is an exceptional metal for abrasion resistance, commonly applied using plasma coating. Its application methods include thermal spray or High Velocity Oxygen Fuel (HVOF) processes. This material is noted for its high Rockwell hardness of 70HRc. This significant hardness allows Tungsten

What’s the Difference Between Teflon and PTFE?

When it comes to non-stick coatings and fluoropolymers, the terms “Teflon” and “PTFE” often get used interchangeably. However, there’s more to this story than meets the eye. Let’s dive into the world of these remarkable materials to understand the difference between Teflon and PTFE.   What is Teflon? Teflon is a name that – to some – has become almost synonymous with non-stick coatings. But in reality, it’s just a brand name, and the heart of this story lies in its underlying material—Polytetrafluoroethylene or PTFE for short. This is the actual substance that is used to give the reliable, durable,

Everything you need to know about non-stick coating

From helping your fried eggs avoid an unplanned scrambling, to maintaining the structural integrity of offshore oil rigs, non-stick coatings are a vital part of day to day life. Having been relied upon for over half a century, these coatings are versatile, and their benefits countless. So, what materials can help us to avoid sticky situations, what’s the science behind their repellent nature, and how does something designed not to stick, coat a surface? Read on to find out.

There’s a better way for foam moulding

What is Moulded Foam and how can we improve it? Moulded foam is commonplace within the automotive industry, and for good reason. Adding comfort – making travelling easier and acting as a noise barrier, making journeys more pleasant, it’s not hard to see why. The moulds however can be expensive, and the production process restricted by the need to non-stick spray them between moulding runs. Messy and time-consuming, there is another way and Sam at Marcote explains how. The current industry standard is for moulds to be sprayed with a wax release agent before the foam is formed. Over time,

The Marcote Process: Sand Blasting

In decades gone by, preparing a material for coating was a laborious, time consuming task that often required treatment by hand. Whilst traditional methods like sanding or wire brushing still exist, busy workshops like ours turn to more modern, time-saving techniques. Enter sand blasting, the surface treatment used to prepare items for coating. How does it work?   Sand blasting works in a way that is unsurprising given its name. During the process of sand blasting, pressurised fluids – such as air, steam, or water – are used to propel abrasive particles towards a surface. This then etches your part

Difference between Plasma and Polyurethane for abrasion resistance

Plasma or polyurethane for abrasion resistance – what’s the difference? Plasma coatings and polyurethane coatings are both popular, long established systems for protecting components against abrasion. Knowing which one is right for your facility can prevent costly coating failure, replacement and extensive machine downtime. Marcote’s surface coating specialists have an unrivalled knowledge of each coating system and many years’ experience specifying and applying the right coatings on an application-by-application basis. To help you make the informed choices, we caught up with Sam Woodcock, Managing Director of Marcote, to discover the difference between two often confused coatings – plasma and polyurethane:
