The substrate is typically the substance on which the metabolic catalyst acts. It refers to a base material on which a coating can be applied and this applies to almost any kind of material.
What is a substrate in terms of materials coating? A substrate is any material used as a base, such as a rubber or plastic that has been imprinted with moulding techniques. Moulding techniques employ high temperatures and pressure, which imprint the mould on the surface of the substrate. When a substrate is used for any purpose, say to form a part of a larger component, the part is formed on a substrate that has been imprinted by the moulds. Most often, a substrate is used as an insulating layer between two pieces of equipment, to keep the equipment from overheating. For more information on HVOF, visit a site like Poetons
One important thing to note is that there are two types of material used to form a substrate. The first type is thermoset polyurethane, which is typically used in industrial applications. Thermoset polyurethane is known for its toughness, even resistance to industrial wear and tear, which makes it ideal for applications such as industrial ovens. The second type of substrate is vulcanized rubber, which is often used in food service. Vulcanized rubber is also versatile, because it can be used to create a wide variety of textures and coatings.
Stainless steel is often used as a protective layer, to protect machinery from grease and corrosion. It is also sometimes used as a substrate to form a protective sheath around a motor, to reduce the internal friction between moving parts. Other forms of protection provided by materials coating are resistance to heat, water vapour, UV rays and chemicals.
