JSU series polyurea spray elastomer

Polyurea Spray is a very versatile coating system for corrosion resistance, waterproofing as well as abrasion protection.
JSU series polyurea spray elastomers are based on reaction-injection molding (RIM) technique and the success of amine-terminated polyether production, providing consistent seamless coating. It contains no solvents and is not affected by moisture or temperature conditions.

Value added features
* Fast reactivity and cure without catalyst
* 100% solid formulations without solvents, thus environment-friendly
* Extraordinary physical properties which can be adjusted in a wide range
* Excellent adhesion to a wide variety of substrates for properly formulated system
* Resistant to chemicals and extended durability, even in extreme environmental condition
* Different colors are available
* Relatively moisture and temperature insensitive during application
* Thanks to their short gel time, they can be apllied on surfaces with any shapes without sagging.

Advantages( Polyurea vs. Epoxy resin)
* much better corrosion-resistant property and better tenacity, while epoxy is hard and crispy. Polyurea has higher hardness and tensile strength.
* Better chemical-resistance.
* elasticity, comfortable for people to walk on.
* extended durability, guarantee 30 years life.
* fast cure, can be walk on in seconds.

Options
JSU-1 Waterproof Spray Elastomer
This product can be used for waterproof in roof, tunnels, bridges, reservoirs, swimming pools and silos. JSU-1 contains compound that increases gel time, therefore the product will have better permeability and adhesion to the surface.

JSU-2 Floor-used Spray Elastomer
It is especially used in indoor, factory, vehicle part place where have requirement of flam-retardant. It can also provide a protective coating for concrete surfaces ,etc.

JSU-3 Abrasion-resistant Spray Elastomer
JSU-3 has high hardness and abrasion resistance, it is extensively used on the floor and walls of bridges and houses.

JSU-4 Collide-resistant Spray Elastomer
JSU-4 has higher hardness and good collide-resistance. Therefore, it shows excellent performance in coating of structures such as chemicals, oil, pipelines, and tanks.

JSU-5 Corrosion-resistant Spray Elastomer
JSU-5 has better corrosion-resistance. It offers a protective lining for chemical tanks and pipes with high demand of corrosion-resistance.

Storage
Shelf life is six months minimum when stored at 59oF~158 oF and dry conditions. Like most construction materials, must be stored in a dry, well-protected and suitable storage environment. Keep containers sealed.

Note
JSU series are aromatic polyurea, therefore, tiny change in color will occurs a periode of time after the application, which, however, will not effect the property.
