Limaenvec are one of the UKs leading specialists in polyurethane and polyurea protective spray coatings.

Polyurethane spray coatings are one of the toughest and most versatile industrial coatings that are available today. Here at Lima Engineering we have developed our own unique spray machines that give us a huge advantage in spray quality and application compared to our competitors.

Because we manufacture our own bespoke Polyurethane spray systems, we can offer a complete insight into the materials, the way they work and how they respond.

Our continuous investment now allows us to offer licences to our markets both at home and abroad for spraying polyurethanes in-house, providing a more practical and cost effective service which no competitor can match.

Why choose LimaEnvec?2016-12-13T09:38:30+00:00

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.

What materials can polyurethane be sprayed on?2016-12-13T09:36:36+00:00

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

What is polyurethane?2016-12-13T09:23:06+00:00

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.
