Polyurea Abrasion Resistant Coating  CAS: 37955-36-5

Polyurea wear-resistant material is the third-generation polyurea elastomer, which is made of raw materials such as on-site spraying quasi-prepolymer, amine-terminated polyether and amine chain extender. This technology has achieved a perfect fusion with new materials and new equipment, which is a qualitative leap in the history of architecture.

 

Features:

 100% solid content without VOC and pollution.

Stable physical and chemical properties;

Strong adhesion to various materials;

After spraying, the reaction is quick, and the equipment can be put into production as soon as possible;

High heat resistance and wear resistance.

 

Abrasion resistance

According to the laboratory test of its wear performance, spraying polyurethane anti-corrosion coating abrasion resistance is 5-7 times the ordinary natural rubber, more than 10 times the carbon steel. The material not only has a high strength, but also has a good buffer, energy absorption performance. Spraying polyurethane anti-corrosion coating strong abrasion resistance determines its wide range of applications in the rock zone operations, through the pipeline outside the corrosion, under circumstances of high flow rate and high erosion. The following table for the abrasion resistance is the comparison between the SPUA-406 pipeline anti-corrosion materials and common materials.

 

Comparison of abrasion resistance between PU material and other materials

Name of material	Abrasion loss/mg	Name of material	Abrasion loss/mg
Spray polyurea	25	Natural rubber	146
Nylon 610	16	Impact resistant PVC	160
Polyester film	18	Styrene butadiene rubber	177
High density polyethylene	29	Plasticized polyvinyl chloride	187
PTFE	42	Styrene butadiene rubber	205
Styrene butadiene rubber	44	ABS	275
Nylon 66	49	Chloroprene rubber	280
High density polyethylene	70	Polystyrene	324

 

Anti-aging performance:

Sprayed polyurethane material has excellent ageing-resistant performance. Although there will be yellowing phenomenon in the aromatic spray polyurethane material, it won't cause pulverization and cracking. The performance changes of aromatic sprayed polyurethane materials before and after artificial accelerated aging test under 50 ºC for 3,871 hours are shown in the following table.

 

Item	Before aging	After aging
Tensile strength (MPa)	13.5	13.5
Elongation rate (%)	137	110
Tear strength (kN/m)	76.4	84.4

 

Application:

Polyurea abrasion-resistant material is specially designed for mining equipment, and is available for the laundering of coal mine, the process equipment of cement mortar, the vibrating screen, the flotation cell, the ore washing cylinder, the spiral separator, the grinding equipment, and the hydraulic classifier.

All the above parameters are the physical properties of  professional equipment after curing under laboratory conditions for 7 days under the conditions of 23 ± 2 ºC and relative humidity of 50% ± 5%.

Drying time (25 ºC), the surface will dry in 3 minutes, and the walking strength can be reached in 10 minutes.

Thickness: 2-10mm (depending on user requirements)

The minimum paint spraying interval: no time limit; the longest: no more than 3 hours.

 

Substrate processing:

The metal substrate should be sandblasted to Sa2.5 grade, and coated with special anti-corrosion primer. Before each application, ensure that the substrate surface is free of any impurities, otherwise it will affect the spraying effect.

After the concrete is completely dry (newly poured concrete should be hydrated first, and then dried for 28 days), remove loose impurities on the surface, spray a layer of matching concrete sealing primer, and spray construction after the primer is cured.

 

Coating method:

The high temperature and high pressure impact mixing equipment specified by our company must be used during construction.

 

Packing specification:

Material A: 220kg / drum; Material R: 210kg / drum.

The packaging can be changed according to user requirements.
