JHSW8302 high loss non-toxic viscous damper material is independently developed by Qingdao Polyswell Technology Co.,Ltd. The viscoelastic material system consists of A component, a quasi-prepolymer rich of free NCO, and B component, a mixture of polyetheramines, hydroxyl-terminated polyether, amine extenders and other additives. JHSW8302 can convert mechanical energy into heat energy by the coactions of resin and energy dissipation filler. It is used by itself or in combination with other materials to produce damping protective coatings, anti collision liners, reinforcing layer, and resilient surface on urban metro, tunnel concrete. JHSW8302 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. JHSW8302 can effectively decrease the vibration, noise and impact of high speed train; it can improve the safety and durability of urban metro.
Advantages:
- Excellent vibration & noise reduction, impact resistant.
- Bondable and paintable to various kinds of substrates
- Excellent Waterproofing and Impervious
- 100% Solids, No VOC's, Odorless, No Toxic Vapors
- Wide service temperature (-45~100 ºC)
- Seamless, flexible, slick and non-porous
Recommended Uses:
JHSW8302 high loss non-toxic viscous damper materiais a fast cure system; it can be applied at thicknesses of several ten millimeters, or greater, in a single application. It can be widely used in urban metro vibration and noise reduction; it can also be applied in vehicle, shipping, machinery and high speed railway noise insulation zone and so on.

As the inventor of polyurea Mr.Dudley Said: "Polyurea is a technology, not a simple products", you will not only need to buy the products, you will need professional technical support during the application.
As a professional R&D manufacture of polyurea, we have developed many different formulation in different application, and we have very rich product line., such as hot spray polyurea, aliphatic polyurea, aromatic polyurea, cold applied polyurea, polyaspartic polyurea, single part polyurea, two part hand applied polyurea...etc. and we can also develop new formulation to our customers.
Being involved in polyurea industry for over 16 year, we also have used many different types of machines, so that we can also provide ourr customer with machine service, and spray skill, in order to help our customer with everything during use polyurea.
If you are the first time use polyurea, we will help you choose the best machine and help you save cost, find the most suitable products for you. If you have use polyurea, but need high quality or special formulation, or have some problem which can't be solved, pls feel free to contact us. We hope to achieve a win-win long-term cooperation with you!
