Spray polyurethane.
Dart valves coated with 4mm thick spray applied polyester polyurethane.
The mild steel dart valve is grit blasted and a bonding is applied prior to coating.
The mild steel dart valve is mounted on a manipulator to aid coating.
The valve is coated to a thickness of 4 mm with tough spray applied polyurethane.
Polyurethane spray for wear resistant applications. Nozzles and shields are coated to provide extended life and to protect the parent metal. Polyurethane provides a low cost extremely durable coating and is primarily used to protect against abrasion.
These pictures illustrate the many different shapes that we can line and one of the benefit’s of our spray system is the elimination of tooling.

Polyurethane (Pu) is a very versatile material which can be moulded into many shapes. A poured open cast liquid requires relatively simple tooling and with the many different grades of Pu products can be tailored to specific requirements.
This post described the lining of steel plates with a polyurea grade polyurethane coating. The project involved coating 8 off curved plates with a 2 mm thick coating. The plates form segments of a large tank used to hold corrosive materials.
Polyurethane spray provides the neccessary properties to withstand chemical attack.
Before Polyurethane spray (grit blasted)
Polyurethane spray coating is a service offered by Lima Envec. High build coatings are achieved when polyurethane is sprayed onto steel. This process is ideally suited to the coating of large complicated shapes where the cost of a mould tool would be prohibitive.
The hopper is ready for a 6mm thick polyurethane coating.
Hopper coated in black spray polyurethane.

This post describes the internal lining of a vessel. A customer required a 6mm thick polyurethane lining in order to protect the substrate from wear, and to ensure that the product would not be contaminated with metal from the vessel. A polyurethane spray applied coating was used to line the vessel and provide a membrane.

Spiral roller coated with polyurethane
This project describes the coating of a spiral roller with 85 shore polyurethane. A customer required a tough coating applying to a fabricated roller. The initial tooling costs involved impeded the progress of the project. Lima Envec offered to spray apply polyurethane rater than produce a mould tool.
This course allowed the project to move forward and the roller is undergoing trials.

Lima Envec are approved applicators for Irathene products. These spray applied polyurethane lining are proven in industry for the smooth finish. hard wearing and tough Irathene coatings are especially suited to small components where fine coatings are required.
Irathane coating
Feeder tray coated in polyurethane
Lima Envec manufacture to customer requirements scraper blades and belt scrapers. From tough durable materials pu belt scrapers remove material from the underside of conveyor belts. Lima Envec also manufacture screen decks and wire mesh coated with spray Pu.
The Limathane range of spray polyurethane coatings has been specifically designed for the one off items or complex shapes, where tooling prices are prohibitive.
These 100% elastomer coatings offer outstanding protection against abrasion and corrosion and for sound reduction applications.
Remarkably tough and hardwearing, these abrasion resistant coatings are available in a choice of standard colours and can be applied to a range of substrates, such as steel, aluminium, GRP, wood and even concrete.
