Polyurea is created by the reaction between diisocyanates and diamines. It is among the strongest synthesized polymer materials. Here are a few characteristics of it:
- Strong strength that has tensile strength over 5,500 psi and tear strength over 500 pounds/in
- 100% solid, with no VOCs. compounds (VOC)
- The range of hardness is wide and can be adjusted all the way to shore D
- Good chemical resistance
- Excellent abrasion resistance
- Water-tight qualities
The reaction of diisocyanate with diamine that results in polyurea can be extremely rapid. Exothermic heat, in turn, accelerates the reaction until it is complete. There is no complicated reactor or the need for strict conditions is required. This makes it possible to mix these two elements in a calculated ratio, and then apply the resultant mixture on the substrate. Different thicknesses of polyurea coatings can be applied to any substrate. In actual use using the use of a high pressure spraying machine is used to apply an polyurea coating by evenly spraying this material over the entire surface. This is the foundation of rapid-setting polyurea spray system.
The quick-setting Polyurea Spray Coatings are used in a variety of industries and markets. The typical raw requirements have very low viscosity, lower freezing point, and high Reactivity. The raw materials need to create a high-strength thin layer to serve its protective functions. Gantrade gives additional raw material options that could improve the performance of your product or provide viable solutions for a variety of new uses. 
The flexibility of polyurea spray systems make them a perfect option for a variety of uses. This blog’s goal is to begin and promote discussions on improvements to existing systems , and to develop new ones with improved endurance, performance and longevity.
Here are five facts concerning quick-setting polyurea spray Systems:
1. Polyurea Spray Coatings serve an Wide Range of Industries
The usage for Polyurea Spray Coatings spans from mine channels to sporting ground. This kind of spray can meet the requirements of many industries, including:
- Construction industry is used for erosion protection, concrete surface protection and waterproofing.
- Manufacturing industry and for surface protection.
- Water industry to store tanks as well as pipeline corrosion protection.
- Chemical industry to process tanks’ corrosion protection and chemical-resistant tank liner.
- Concrete industry provides floor sealants, protective coatings, surface repair as well as waterproof surfaces.
- Military industry to provide outdoor dwellings and reinforcement.
- The oil and gas and coal mining industries, to ensure abrasion resistance as well as corrosion protection.
This list only represents an example of a many industry applications.
2. Polyurea Spray Coatings Serve Different Purposes
Polyurea Spray Coatings are utilized for a variety of purposes even within a specific market segment.
For example railroad companies may utilize a polyurea system to keep an aggregate from damaging railcars’ surface upon impact and an alternative system to avoid corrosion on other surfaces made of metal.
Other tasks include:
- The enhancement of strength and strength of a piece or preventing parts from damage and tear such as in the case of truck bedliners.
- Surfaces that can be waterproofed in a pool pool or reservoir.
- Protective coatings on wood surfaces to stop scratching and scuffing.
- The reinforcement of padding or fabrics for strength, such as roofing materials as well as military clothing coatings.
- Softening or hardening the surface, like the tabletop, by applying spray-on coating to provide a more comfortable feel or better impact resistance.
- Protection of tunnel surfaces from impact and blasts.
- Offering the environment with rust protection on metal surface.
From tiny, 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 used.
3. A spray of polyurea Coatings are a popular Material of choice for a variety of applications
With their numerous industry applications and a myriad of purposes, it’s not surprising that quick-setting Polyurea Spray Coatings can also be used in many applications. Here are a few examples:
- Spray coatings for truck bedliners as well as concrete-mixing tank liners.
- Underground Surface spray layers that form an waterproof barrier to structures, sewage tanks or for building uses
- Surfaces made of rock or sand spray layers that offer erosion protection for golf courses and playgrounds, and aid in maintaining an attractive landscape
- Applications for decorative purposes, such as decorative car coatings or even top-quality car waxes
- Fertilizers (processed by) spray coatings of polyurea that provide a unique time-release due to the gradual breakdown of the thin layer of polyurea
The possibilities for polyurea spray coating application is growing. Selecting the best spray polyurea method will provide an extended period of protection for a variety of applications, no matter the dimensions or shape.
4. Polyurea Spray Coatings come in a variety of forms
The layers that are created by rapid-setting polyurea spray coatings could have different levels of hardness dependent on the formulation. They can be foam or elastomeric transparent or colored, matte or shiny, as hard like glass or less hard than rubber, and layered by fillers, or a thin film.
It all depends on what the requirements are for the particular application.
A distinct form of polyurea spray coating and environmental-resistance properties can be achieved by choosing different chemicals or their combinations.
5. Polyurea Spray Coatings are modified to suit specific requirements.
Although the majority of spray coatings have to be applied similarly by using the high pressure spray guns, more extended gel-time formulations are applied by rolling. Modifying the formulation allows for individualization for a particular application.
The surrounding environment, the purpose the intended function, the hydrolytic resistance either the character of application and thermal shrinkage operating temperature range and additional factors should be taken into consideration to make a sound material selection.
Here are a few issues to think about:
- What type of protection is needed?
- Does the application requires impact or abrasion resistance?
- What kind of abrasion is the most common whether impingement or sliding?
- Does the nature of the application either static or dynamic?
- What is the significance of resistance to direct sun and UV exposure vital?
- What is the anticipated operational temperature?
- What type of chemical exposure is to be anticipated?
- Are hydrolytic resistance crucial? Operation in a hot and humid environments?
For instance, a bath tub application requires a different formula as compared to an outdoor swimming pool application as it requires more UV resistance as well as chemical (chlorine) resistance. However, these formulas are quite different than the tough abrasion resistant coating required for the Fracking pipeline liner. But all three of them require an excellent hydrolytic resistance.
In the selection of the most suitable quick-setting polyurea, Gantrade has an vast selection of diamine-based curatives that can be utilized in both TDI and MDI system:
