VQ-800

VERQUARE VQ-800 is the Nano Densifier especially designed for the concrete floor with the distinctive performances in the functions of dust-proof, abrasion-resistance, and sealing effect. The raw liquid of VQ-800 is physically transparent, odorless, non-toxic, and non-flammable. After being applied on the concrete, VQ-800 can strongly penetrate into the concrete to a depth of about 6-10 mm from the surface and react with Ca+, Mg+ to form an cross-linking network called “Silicone-crystallizing entity” of which the MOHS value is around 8-9. The “Silicone-crystallizing entity” can efficiently seal the pinholes of the concrete and avoid the particles departing from the surface of the concrete due to weathering.

The floors of factories, workshops, supermarkets, logistic warehouses, airport runways, food processing and medicine manufacturing establishments, parking lots, slaughter houses, expressways, bridges, tunnels, ports, sports centers, and etc., which are made of concrete, terrazzo, or emery focusing on the effect of abrasion-proof of the floor.

VQ-800, the Concrete Nano Densifier, can change the structure of the concrete by its effective permeability to conduct a chemical reaction with the original chemical compositions existing in the concrete itself, which can form a compact integral in the three-dimensional space so as to make the micro-interspaces of the concrete smaller and make the gel structure become bigger and stronger so that all kinds of compositions in the concrete can be solidified to a solid entity which is dust-free and compact. Thus, the strength, the hardness, and the abrasion resistance of the concrete floor will get greatly enhanced. In addition, the agent of VQ-800 also can be used to seal up the voids and the gas holes of the concrete so as to avoid the permeation of the pollutants, the grease, and the moisture, which can prevent the particles departing from the voids on the surface of the concrete permanently.

High Hardness	The MOHS value can achieve 7-9. The hardness value can be upgraded to 3 levels after the application.
Abrasion Resistance	The value of abrasion resistance can be enhanced to over 400% (ASTM C944;1999)
Non-slip	The dry/wet coefficient of friction > 0.6 (ASTM D1894-14), which can improve the disadvantage of the floor’s slippery problem efficiently.
Compressive Strength	The value of the compressive strength can be increased up to 7.5% according to the standard test of ASTM C39.
Tensile Strength	The value of the tensile strength can be increased up to 30% according to the standard test of ASTM C307.
Penetration Resistance	The silicone-crystallizing entity can seal the surface of the concrete thoroughly and reduce the permeability of water, oil, and stain efficiently.
Dust-proof	Can prevent the particles departing from the voids on the surface of the concrete efficiently so as to enhance the dust-proof effect.
High Gloss	After application, the gloss of the concrete will be similar to marbles, and the surface gloss will get higher and higher as time goes by.
Weathering Resistance	Can keep Cl+ from passing through the concrete and won’t be affected by UV, water, fog, and electromagnetics.
Corrosion Resistance	After treatment, the ability toward the concrete’s corrosion resistance can be largely enhanced.
Eco-friendly	The features of VQ-800 is transparent, non-toxic, and non-flammable, which belongs to eco-friendly materials.
