1、 Product Core Definition

Cold applied epoxy marking paint is a room temperature construction type marking paint based on epoxy resin as the core film-forming material, combined with high-quality pigments, functional additives, and environmentally friendly solvents. Its core feature is that it does not require high-temperature heating equipment, and can quickly form a film through room temperature brushing, rolling or spraying, forming a marking coating with high strength adhesion and durability. It is widely used in traffic guidance, area division and safety warning scenarios, and is an environmentally friendly marking solution that replaces traditional hot melt coatings.

This product strictly follows the industry standard of "Road Marking Coating" (JT/T 280-2004), and has been certified by the Traffic Engineering Testing Center of the Ministry of Transport. It meets national regulatory requirements in key indicators such as adhesion and reflectivity, and is suitable for various substrate surfaces such as cement and epoxy flooring.

2、 Core performance characteristics

1. Fast drying at room temperature, efficient construction

No professional heating equipment is required. After opening the bucket and mixing according to the ratio of main agent and curing agent, construction can be carried out, greatly reducing equipment investment and energy consumption costs. At a room temperature of 25 ℃, the surface drying time can be controlled within 10-15 minutes, and the actual drying time does not exceed 60 minutes. Compared with hot melt coatings, it greatly shortens the time for road closure and site occupation. Even in enclosed spaces such as factory workshops and underground parking lots, rapid solidification can reduce the interference of construction on production and operation, especially suitable for marking projects with high traffic flow and tight schedules.

2. Strong adhesion, wear resistance, and durability

Through the chemical bonding between epoxy resin and substrate, a strong adhesion layer is formed. When tested using the cross cut method, the coating does not peel off, and the adhesion index reaches over 2MPa, far exceeding the industry's upper limit standard of 4.0MPa. The paint film is reinforced with special wear-resistant aggregates, and the weight loss in the 200 rpm/1000g wear test is only 23.6mg, far below the industry standard of 40mg. It can withstand long-term friction and mechanical rolling of car tires without fading or peeling. In high-frequency usage scenarios such as parking lots and factory workshops, the service life can reach 3-5 years, reducing maintenance costs in the later stages.

3. Weather and corrosion resistance, strong environmental adaptability

The paint film forms a dense network molecular structure, with excellent acid and alkali resistance, oil and grease resistance, and aging resistance. It can withstand corrosion from gasoline, diesel, industrial solvents, and daily chemicals, and can maintain stable performance in special environments such as food processing workshops and chemical warehouses. After accelerated aging test, the color difference is ≤ 3, and it does not crack or soften in environments ranging from -10 ℃ to 70 ℃. At the same time, it has outstanding UV resistance and can maintain a bright color even after 3 years of outdoor use. There is no color bleeding phenomenon on asphalt pavement, and it can stably adhere to both new and old cement surfaces without frequent repair and maintenance.

4. High brightness reflection, safety guarantee

High refractive index (≥ 1.9) reflective glass beads are standard, with a spreading amount controlled at 0.3-0.5kg/㎡. After drying, the reflectivity coefficient can reach 81mcd · m ⁻² · lx ⁻¹ (white) and 52mcd · m ⁻² · lx ⁻¹ (yellow), far exceeding the industry's minimum requirements of 75 and 45. Under the illumination of night lights, clear reflective effects can be formed, and good visibility can still be maintained in rainy night environments, effectively improving the safety of nighttime traffic at parking lot entrances, community roads, and campus surroundings.

5. Environmental friendly economy, in line with the dual carbon concept

Adopting a low VOC environmentally friendly formula, solvent based products have a solid content of ≥ 69.9%, water-based products have extremely low VOC emissions, and the construction process produces no dust or harmful gases, meeting the standards for environmentally friendly coatings. Compared to the high-temperature carbon emissions during the construction of hot melt coatings, the lifecycle carbon emissions of cold coated epoxy marking paint are reduced by more than 60%, with a global warming potential value of only 1.00, which helps to promote the low-carbon transformation of road construction. The comprehensive calculation of material cost and labor cost shows that the cost-effectiveness of hot-melt coatings is 20% -30% higher, especially suitable for large-scale marking projects.

6. Rich colors and flexible applications

We usually provide traffic standard colors such as white and yellow, and can also customize multiple colors such as red (warning area), blue (fire escape), green (safety escape), etc. to meet the needs of different functional areas. The surface of the paint film is smooth and clean, with excellent coverage. The coverage of white paint is 98%, and that of yellow paint is 85%. Different line widths ranging from 100-300mm, as well as complex patterns such as directional arrows and text markings, can be designed according to requirements, with a line accuracy deviation of ≤± 5mm.

3、 Applicable scenarios and typical applications

1. In the field of transportation and roads

Suitable for marking lane lines, stop lines, no parking areas, etc. around urban branch roads, residential roads, schools, and gas stations, reducing traffic congestion with rapid solidification characteristics; In temporary marking scenarios such as driving school training grounds and temporary parking lots, it has both economic and removable advantages.

2. Industrial and warehousing fields

Widely used in workshop channels, equipment positioning lines, material zoning lines, as well as location marking and loading/unloading area identification in logistics warehouses of manufacturing factories such as electronics, machinery, food, and medicine. Its oil resistance and easy cleaning characteristics are particularly suitable for industrial environmental requirements.

3. Public and commercial places

Enhance spatial guidance efficiency through vivid colors and clear reflective effects in underground parking lots of shopping malls, hospital passages, sports venues, and other places; In nursing homes, kindergartens and other places, anti slip warning lines can be set up to balance safety and aesthetics.

4. Special functional areas

In corrosive environments such as chemical parks and laboratories, as well as extreme temperature scenarios such as cold storage and high-temperature workshops, its stable weather and corrosion resistance can ensure the long-term effectiveness of the marking; In high-end decoration sites such as epoxy flooring and terrazzo flooring, the construction is color free and undamaged, perfectly matching the needs of high-end sites.

4、 Key points for construction and storage

1. Preparation before construction

The substrate needs to be dry and clean (moisture content ≤ 6%), removing oil stains, floating dust, and residual old markings. For cement floors, it is recommended to first apply epoxy sealing primer to enhance adhesion. The construction environment temperature should be controlled between 5-35 ℃, with a relative humidity of ≤ 85%, and construction should be avoided in rainy, windy, or direct sunlight conditions. According to the design requirements, use an ink fountain to mark the reference line. Set control points every 50m for straight sections and increase the density to every 10m for curved sections to ensure a straight and accurate line shape.

2. Construction method

Hand pushed or vehicle mounted cold spray marking machines (pressure 0.3-0.5MPa) are used for large-scale construction, with nozzles 10-15cm above the ground and moving at a constant speed (2-4km/h) to ensure uniform thickness (0.2-0.4mm); For small areas, brushing or rolling can be used, and the same direction should be maintained during brushing to avoid sagging. If viscosity needs to be adjusted, the amount of special diluent added should be controlled at 0-5% and should not be excessive to avoid affecting performance.
