What is polyurethane?
Polyurethane is classed as a plastic material, which comes in various forms. It can be manufactured to be either flexible and soft (like rubber) or rigid (like hard plastic). Polyurethane is very versatile and can be poured, moulded, cast and sprayed. It can provide a stronger coating than plastic dip method.
What are the advantages of using polyurethane?
Easy to coat and produce complex shapes
Touch dry in 15 seconds
Wide range of hardness and colours
Extremely wear resistant
Doesn’t react with water, fuel and other everyday chemicals
Spray thickness from 1mm to 50mm
Wide choice of colours
Low cost moulds
Extremely fast process

Why choose polyurethane over rubber?
Unlike rubber, polyurethane is extremely resistant to abrasion.
Provides high cut and tear resistance
Will not deteriorate when exposed to everyday chemicals, such as oil, petrol and other solvents
Has a much broader hardness range than rubber
Available in a wide range of colours
Lower cost low pressure tooling as opposed to high pressure rubber tooling. No vulcanisation required
What materials can be sprayed on?
Virtually any material can be sprayed onto. The process involves cleaning the product and applying a bonding agent if required. When done correctly, the spray coating is extremely difficult to remove.
Examples of the types of material that we have sprayed on are: metal, wood, GRP, fabric, foam, cardboard, concrete, mesh.
Why choose Lima Engineering?
We are one of the UKs leading experts in the manufacture of polyurethane products. Our team of engineers are incredibly knowledgeable and will provide you with the correct process to meet your requirements. Unlike some of our competitors, who use off the shelf spray machines, our bespoke machines have been specifically designed to spray fast setting polyurethane and polyurea coatings to a wide array of components. The machines we use ensure there is no delamination, zero defects, 100% mixing, fine smooth surface finish and the ability to produce very thin tough linings.
Our self contained spray area and shot blast booth enables us to prepare and spray items up to 10m x 5m in size.
