Industrial Lining vs. Coating
What's the Difference?
When it comes to industrial lining and coating, there can be a lot of confusion about what the difference is. In short, a lining is an inner barrier, and a coating is the outer barrier. But there are some other key differences that you should know about.
In the context of the industrial based roof and surface lining and coating, we'll discuss the differences in various factors, including performance, application methodology and costs.
What is Lining?
A lining is defined as a protective layer applied to the inner surface of a structure. There are several uses for linings that are made of different materials.
For example, linings can be used to prevent corrosion. Others improve the overall durability of a particular structure. Linings may also be utilised in the containment of liquids. Systems such as drainage channels, gutters, gullies, and ponds benefit from linings. They enable the structure to hold large quantities of liquid, whether drinking water or chemicals like fuels and solvents.
What is Coating?
A coating is defined as a protective layer applied to the outer surface of a structure. Unlike lining, coats are generally thinner.
There are many reasons why you might want to coat a particular structure. One of the most common reasons is to protect the surface from weathering and corrosion. Depending on the material, certain coatings have UV-protective qualities. They can also prove to be effective for physical impacts to maintain the structure and chemical spills to protect whatever it is that holds the coating.
A coating can be used in applications such as vehicles, machinery, buildings and roofs.
Industrial lining and coating systems
Fibreglass (GRP) Linings & Coatings
Fibreglass (GRP) linings and coatings are glass-fibre reinforced plastic composites. This material offers versatility and durability within its application and can be applied to various surfaces.
GRP flat roofs are one of the most common applications of this material. Its waterproofing properties prove helpful for the building industry creating long-term durability for flat roofs. Other typical applications include Steel and GRP water tanks, bunds, cooling towers and drainage channels.
There are plenty of benefits of Fibreglass (GRP) linings and coatings. Once applied, the product is virtually maintenance-free. however, there are fibreglass repair kits available, should you need to make repairs. It is drinking water compatible, a poor conductor of electricity and is fire retardant. Along with plenty more benefits, this material provides practical applications.
Epoxy resin is a thermosetting plastic formed from an epoxide "resin" reaction with a polyamine hardener. Epoxy lining provides excellent adhesion to various surfaces and can be used to extend the lifetime of various surfaces due to its strong bonding properties.
Standard applications for epoxy resin coatings include walls & floors, water storage tanks, and bunds. Offering excellent durability, the material is low-maintenance and provides protection against chemical, biological and mechanical stress.
Polyurethane Linings and Coatings
Polyurethane lining and coating systems are two-part reactive lining systems. They offer a range of benefits for various lining applications.
This lining system is often used as an alternative to epoxy lining due to its flexibility. Structures such as corrugated metal roofs, which are prone to movement, greatly benefit from the use of this material. The polyurethane lining or coating reinforces the frame to enhance its strength.
