Polyurea is made by the reaction of diisocyanates with diamines. It is among the most durable synthesized polymer materials. Some characteristics of it:
The highest strength has a tensile strength over 5,500 psi and tears strength greater than 500 pounds/in
100% solid, with no volatilized organic compounds (VOC)
A wide range of hardness that can be adjusted all the way to shore D
Good chemical resistance
Excellent abrasion resistance
The diisocyanate and diamine reaction that results in polyurea is very rapid. Exothermic heat, in turn, accelerates the reaction until it is complete. The reactor is not complicated, nor is the need for strict conditions required. This makes it possible to mix the two components in a calculated ratio and then apply the resultant mixture to the substrate. Different thicknesses of tough polyurea coatings can be applied everywhere on different substrates. In the real world, a high-pressure spraying device is employed to apply a polyurea coating by spraying it evenly over the material onto the substrate. This is the basis of rapid-setting polyurea spray equipment.
The spray coatings that set quickly provide a wide range of markets and industries. The most common raw requirements are very low viscosity, lower freezing point, as well as high speed of reaction. These raw materials require a strong, thin layer for their protective functions. ArmorThane provides additional raw material choices which can improve product performance or offer viable solutions for many new applications. polyurea-spray-coatings-gantrade
The ability to customize polyurea spray systems makes them a perfect option for various uses. This blog aims to initiate and stimulate discussions on improvements to existing systems and to develop new ones that offer improved endurance, performance, and longevity.
Here are five facts concerning quick-setting polyurea spray Systems:
- Polyurea Spray Coatings serve the needs of a Wide Range of Industries
The application for Polyurea Spray Coatings spans from the mining channels to the sports ground. This kind of spray can meet the requirements of many industries, for example:
The construction industry uses erosion protection, concrete surface protection, and waterproofing.
Manufacturing industry and for surface protection.
The water industry is used for storage tanks and pipeline corrosion protection.
Chemical industry to process tanks’ corrosion protection and chemical-resistant tank liner.
The concrete industry is used to supply floor sealing agents, protective coatings, surface repair, and waterproof surfaces.
Military industry to reinforce outdoor dwellings.
The oil, gas, and coal mining industries ensure abrasion resistance and corrosion protection.
This list is only one small portion of the vast array of industry applications.
- Polyurea Spray Coatings Perform Different Purposes
Polyurea Spray Coatings are utilized for various purposes, even within a specific market segment.
For example, railway companies could utilize a polyurea system to stop an aggregate from causing damage to the railcar’s surfaces upon impact and an alternative system to avoid corrosion from other metallic surfaces.
Other tasks include:
Enhancing a component’s strength or preventing parts from damage and tear, such as in truck bedliners.
Surfaces that can be waterproofed in a pool or reservoir.
Protective coatings for wood surfaces protect against scratching and scuffing.
Fabrics or padding are reinforced to ensure durabilities, like roofing materials or military clothes coatings.
Hardening or softening a surface, like tabletops, using a spray-on coating provides a more comfortable feel or better impact resistance.
Guarding tunnel surfaces against impacts and blasts.
Offering the environment rust protection to metals.
From small spray-coated fracking sands to large spray-coated mines or highway passageways, There are a huge variety of applications in which polyurea spray coating equipment is in use.
- A spray of polyurea Coatings is a material of choice for a variety of applications
Polyurea Spray Coatings can also be used in numerous applications. With their numerous industrial uses and applications, it’s no surprise that they are fast-setting. Here are a few examples:
Spray coatings for truck bedliners as well as concrete-mixing tank liners.
Underground Surface spray layers that provide a waterproof barrier to structures, sewage tanks, or for construction purposes
Surfaces made of rock or sand spray layers that offer erosion protection for golf courses and playgrounds, and aid in maintaining an attractive landscape
The decorative applications include decorative car coatings or even top-quality car waxes.
Fertilizers (processed by) spray coatings of polyurea that provide a unique time-release from the gradual decomposition of the thin layer of polyurea.
The possibilities for polyurea spray coating application are constantly growing. The right spray polyurea method will provide long-lasting surface protection for various applications, regardless of size or shape.
- Polyurea Spray Coatings Come in Different Shapes
The final layers that form fast-setting polyurea spray coatings may differ in hardness according to the formulation. They could be foam or elastomeric transparent or colored, matte or shiny, as hard as glass or less hard than rubber, shaped with fillers or a thin film.
It is all about what the requirements are for a specific application.
A distinct form of polyurea spray coating and environmental resistance properties can be achieved by choosing different chemicals or combinations.
- Polyurea Spray Coatings are modified to suit specific requirements.
Although most spray coatings can be applied similarly by using powerful spray guns, more extended formulations with longer gel times can be applied by rolling. Modifying the formulation allows for individualization for a particular application.
The setting, the intended purpose, the intended function, hydrolytic resistance, the dynamic or static character of the application, thermal shrinkage operating temperature range, and many other factors should be considered when making a material selection.
Here are some questions to think about:
What type of protection is needed?
Does the application need impact or abrasion resistance?
What kind of abrasion is most prevalent, either impingement or sliding?
What is the purpose of the application, either static or dynamic?
Why are resistance to direct UV light and sun exposure crucial?
What is the anticipated working temperature?
What type of chemical exposure is to be anticipated?
Is hydrolytic resistance vital? Operation in a hot and humid environment?
But, the formulas for those applications differ from the tough abrasion-resistant coating required for a Fracking pipe liner. For instance, a bathtub application requires a different formula than a swimming pool application because it requires more UV resistance and chemical (chlorine) resistance. However, all three applications require high hydrolytic resistance.
