Two-component Pure Polyurea Protective Material for High-speed Railway Subgrade EX-951

Two-component Pure Polyurea Protective Material for High-speed Railway Subgrade EX-951

Description

EX-951 high-speed railway subgrade polyurea protective material is a two-component elastic material composed of a semi prepolymer with A component as the end NCO group and B component as the end amino polyether, amine chain extender, and additives. EX-951 can be used alone or in combination with other materials as a surface protective coating, lining, wear-resistant layer, and shock-absorbing layer for high-speed railway concrete subgrade or other substrates. EX-951 can form hard coatings of different thicknesses and can be applied to various occasions and handle suitable substrates. EX-951 is insensitive to moisture and humidity and can be used in harsh environmental conditions.

Key Characteristics

• Fast curing speed, continuous spraying on the facade and top without sagging.
• Excellent physical properties, with good adhesion to various substrates.
• Not sensitive to moisture and temperature, with good thermal stability.
• 100% solid content, no VOC, no pollution, environmentally friendly.
• Has excellent anti-corrosion, anti slip, anti-seepage, and wear-resistant properties.
• Good weather resistance, no powdering, and no color loss.
• The coating is seamless and has a smooth appearance.
• Can be manually pelletized to achieve a "protrusion" effect, beautiful and anti reflective.

Application

EX-951 high-speed railway subgrade polyurea protective material has an extremely fast reaction speed, with a single spray thickness of tens of millimeters. The coating has a uniform and beautiful appearance, and can be widely used for high-speed railway concrete subgrade protection; And it can be applied to the protection of bridge piers of cross sea bridges, the protection of inner walls of underwater tunnels, waterproofing of urban subways, waterproofing of roofs of high-end buildings, concrete stands of sports venues, factories, ship decks, and anti-corrosion of offshore drilling platforms.
For applications that require anti rotation and extinction, its extremely fast reaction speed can be utilized to directly obtain a "protrusion" coating with uniform particles on the surface through spraying.
