ZS-1 Thermal Barrier Coating (1000℃) is made from synthetic silicate solution, aluminum silicate fiber, heat reflective materials and selected hollow ceramic micro-beads.All of these components are specially synthesized by ZSWH Chemical Company. There is only one inorganic component in the coating.At high temperature or normal temperature, there is not any peculiar smell emitting from the coating, and any harmful substances generated in the coating.
Since the thermal conductivity of ZS-1 TBC(1000℃) is only 0.03W/m.K(tested in 70℃), the coating barrier can effectively inhibit thermal radiation and conduction. Its thermal barrier efficiency can reach about 90%. For high-temperature objects, it can prevent thermal radiation and heat from losing. For low-temperature objects, it can reserve cold and effectively inhibit the loss of cold caused by environmental thermal radiation. Besides, it can prevent the objects from generating condensed water.
1) Thermal insulation: This coating can effectively prevent heat transfer and keep the inherent temperature and energy of the object, in order to achieve the effects of thermal insulation, cold keeping, anti freezing or reducing heat radiation,etc.

2) Adhesion: This coating can 100% attached to surfaces of objects. With its strong bond, it can be completely bonded with materials and firmly attached to surfaces of objects.

3) Tensile strength and elasticity:The coating can prevent expansion and shrinkage of objects,which is due to different temperatures caused by cold and heat.It has good tensile strength and elasticity.

4) Hazards: This coating does not emit any peculiar odor, does not contain or generate any harmful VOC substance, carcinogen or any other harmful polymers, decomposition and by-products.

5) Stability: The chemical property of this coating is stable, and it does not react with any other substances. It is  not affected by acid, alkali or other corrosive substances.

6) Abrasion resistance: The ceramic particles in the coating are closely stacked while the solvent is composed and strengthened. The abrasion resistance is enough good to be 3-4 times of ordinary steel.

7) Excellent toughness: This coating can effectively prevent fracture caused by fight or thermal shock when it is used.
The film-forming material of ZS-1(1000℃) is made from inorganic silicate solution and its filler is made from some solid materials of hollow glass nano-beads, aluminum silicate fiber and thermo-reflective energy-saving materials.
All the components of this coating are inorganic materials. Among these components, hollow glass nano-beads constitute more than 80%, and the scree size is more than 80 mesh. After the air inside the nano-beads are heated, there is no thermal convection anymore.Nor is there thermal convection in the air layer among these nano-beads. Even if there is difference in temperature, there is no thermal convection.
Sustained by the inorganic materials, the coating functioned as a thermal barrier made of static air and inorganic materials. Supplemented with heat-reflective energy-saving materials, the thermal conductivity of the coating is close to the thermal conductivity in the vacuum. The low thermal conductivity also contributes to the good effect thermal barrier.
According to the above structure, ZS-1(1000℃) works very similar to hundreds of Thermos bottles stacked together. Since some fiber inorganic materials has been added to the coating, the coating is added in the , cracks can be avoided on each coat and the effect of thermal shock resistance is good.
During the sales of this coating, ZSWH Chemical has improve it by three methods, in order to enhance its thermal insulation performance. The improvement is based on continuous technological innovation, thousands of tests in laboratories and continuous feedback of applications from our clients. 
1) Some natural active materials,which can release the same electric charges, are added into the ceramic micro-bead. 
2) Ceramic micro-bead wall is no longer solid, but hollow.This means there are air layers inside the ceramic beads.
3) The thickness of ceramic beads wall is more uniform.
By the above technological innovation of R&D, inside the micro-beads and among them, there is not only static air or a vacuum,but also a large amount of ions with the same charges. The electromagnetic waves emitted by the ions with the same electric charges can effectively shield the thermal electromagnetic wave, more effectively preventing thermal conduction and completely eliminating the free air layer. The hollow layer on the inner wall of the ceramic beads and the thickness of the wall are uniform, in order to effectively reduce the thermal conductivity of the coating and  compression strength.Besides, expansion coefficient becomes more uniform.

When this coating is coated on the surfaces of high temperature pipes, molds, boxes, equipment, furnaces (inside and outside), containers, it can effectively inhibit the heat radiation and heat loss, heat insulation rate can reach more than 90%.

1) Coat this coating on the surface of the tested object in the thickness 8mm, then the temperature of the surface can go down from 1100℃ to 100℃.

2) Coat this coating on the surface of furnace chamber or the outer surface of  a kiln, in the thickness of 6mm, then it can reduce heat loss by more than 30%.

3) Coat the coating on the mold at a high temperature, then it can reduce heat loss to improve energy efficiency.By using this coating,  energy saving rate can be increased by more than 90%. This coating can also improve mold forming rate to greatly reduce defective products.

4) In the condition of normal temperature, coat the coating on the box where there is -30℃, in the thickness of 10mm. Within 24 hours, the temperature inside the box is kept lower than 30℃.

5) The chloride ion content of the coatings is 0, then it can prevent the wet chloride or sulfide in the air or process moving into the metal surface covered by the coating. As a result, it brings a good effect of anti-corrosion for metals. Besides, it does not cause embrittlement of metallic weld.

6) The coating can be used for flue, air duct, wind shield, funnel machine and other equipment. This coating also has an excellent performance of wear-resistance and impact resistance while it is insulating heat.

10) The coating can also be used as a fire retardant coating. It is classified as a kind of thick fireproof coating. According to different fire rating requirements of different materials, the thickness of the coating is also different. Its coating layer can stay in fire for a long time, without deformation. So this coating can be a good heat insulation to protect objects from damage.
