Polyurea consists of…
... a solvent-free two-component material.
Polyurea is created in the chemical reaction of an isocyanate - aromatic or aliphatic (UV stable) formulation - and a polyamine, as a hardener component, using high temperature and pressure.
Processing of polyurea
The components are sprayed on substrates using temperatures of 60 to 70 °C and pressures of 120 to 200 bar.
Due to the short dripping time of polyurea of only a few seconds, it must be processed immediately.
The right combination of pressure, temperature and distance to the substrate ensures a high surface quality and optimal physical properties.
Larger coating thicknesses can be achieved by applying several times. The last process step determines the nature of the surface.
Additives for functional properties such as slip resistance, flame retardancy or food safety as well as pigments can be added to the coating materials.
The advantages of a polyurea coating can be summarized as follows:
1. 100% solid content:
The spray system is solvent-free (VOC-free: free of volatile organic compounds) and is therefore environmentally friendly
2. High resistance:
The coating is resistant to abrasion, is UV and chemical resistant
3. Corrosion protection:
The coating is waterproof and protects metal from corrosion through thick layers. Possible residual moisture on the substrate does not represent a negative influence
4. Fast further processing:
The coating is completely cured after just 24 hours and is 100% resilient
5. High temperature range:
Polyurea can be easily processed between -50 °C and 150 °C and remains elastic
Polyurea shows the following properties:
- impermeable to water
- noise reducing
- wear-resistant / durable
- food safe
- corrosion protection
- high temperature resistance
Compliance with the PIEK requirements
Polyurea coatings have a noise-reducing effect and help to implement the PIEK regulation launched in the Netherlands. Vehicles and handling equipment may only generate noises <60 dB (A) during loading and unloading during night-time deliveries.
Transportation Safety Floors
- Compared to alternative anti-slip mats, load securing cannot be forgotten or lost. This means that there are no penalties to fear during controls.
- Shorter loading and unloading times as there is no need to position anti-slip mats.
- No risk of injury to staff (anti-slip mats no longer have to be placed under transported goods)
- High resilience of the coating
- Chemical resistance to oils, fats, fuels and road salt
- High elasticity at extremely low (–60 °C) as well as at extremely high temperatures (+50 °C)
- Extremely low flammability
- Noise reducing - PIEK requirements
- Fast amortization of costs through time savings, durability and the elimination of anti-slip mats.
- Use in transporters
- Installation of the strips in the lower area of the drop sides
- high wear protection
- lower noise pollution during loading and unloading - PIEK requirements

Handles, grab handles and bended pipes
Various bended pipes, handles or grab handles can be coated with polyurea due to different reasons like ...
- corrosion protection,
- improved feel,
- protection against damage,
- wear protection etc.
