PRODUCTION INFORMATION
Production Description
Qtech-413 Urban Metro Vibration & Noise Reduction Damping Material is independently developed by Qingdao Shamu International Trade 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. Qtech-413 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. Qtech-413 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech-413 can effectively decrease the vibration, noise and impact of high speed train; it can improve the safety and durability of urban metro.
Advantages
1. Excellent vibration & noise reduction, impact resistant.
2. Bondable and paintable to various kinds of substrates.
3. Fast cure, short down time, no sagging.
4. Excellent Waterproofing and Impervious.
5. Ambient insensitive, good thermal stability.
6. 100% Solids, No VOC’s, Odorless, No Toxic Vapors.
7. Good resistance to a wide range of chemical attack.
8. Good weather ability, Added color stability.
9. Wide service temperature (-45~150 ºC).
10. Seamless, flexible, slick and non-porous.
Recommended Uses
Qtech-413 Urban Metro Vibration & Noise Reduction Damping Material is 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.
