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.
Benefits
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
- UV-resistant
- noise reducing
- elastic
- tough
- wear-resistant / durable
- anti-slip
- 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.
Application Examples
Transportation Safety Floors
Advantages
- 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.
Rubbing Strips
Application
- Use in transporters
- Installation of the strips in the lower area of the drop sides
Advantages
- high wear protection
- lower noise pollution during loading and unloading - PIEK requirements
