In our life, the commonly used customized road marking spray paint Manufacturers china are mainly cold coating marking paint and hot melting marking paint. There are specific differences in application and construction. Sometimes we don't know how to choose. Let's take you to know the characteristics of these two products and their differences? So as to give you reference in product selection.

There are two kinds of commonly used customized road marking spray paint Manufacturers china: cold spray road marking coatings and hot melt road marking coatings. The differences between the two are as follows:

1. Product form

The cold spray marking line is packaged in liquid paint (water-based and oil-based) barrels; Hot melt marking is powder and packed in woven bags.

2. Commodity type

The hot-melt marking paint is divided into hot-melt pavement marking paint, hot-melt protruding pavement marking paint and color anti-skid pavement marking paint.

Cold spray marking paint is divided into single component or two-component cold spray marking paint, scratch coating marking paint, structural marking paint, color anti-skid pavement marking paint, water-based pavement marking paint, fluorescent marking paint and all-weather reflective marking paint.

3. Construction comparison

The hot-melt marking paint is in the form of solid powder at normal temperature. During construction, the paint should be put into the melting kettle. The temperature in the kettle should be controlled between 180 ° C and 210 ° C. It should be stirred at the side of the melting kettle. After melting into a molten flow state, it should be put into the thermal insulation melting hopper of the marking truck.

Then, the dissolving paint is introduced into the marking bucket, and the material is kept in a molten state for heat preservation. At the position marked by the pre marking machine before marking, and at the application position indicated on the design drawing, the primer shall be applied with the down coating machine. The standard coating can be applied only after the lower coating is completely dry.

The cold spray marking paint can be directly applied for marking without heating. The marking paint can be diluted with thinner directly and drawn with brush, roller or cold spray marking machine. The color is clear and the process is relatively simple.
4. Product consumption
The film thickness of cold spray marking paint is between 0.3mm-0.9mm, and the general construction thickness is about 0.5mm. Only 0.25kg of materials are required for cold spray construction per square meter.

The film thickness of the hot-melt standard paint is 0.9mm-3.3mm, and the general construction thickness is about 1.5-1.8mm. The hot-melt standard paint needs 4-5kg per square meter.
5. Service life
The shelf life of the cold spray marking paint is one year according to the relevant national standards, and the shelf life of the hot spray marking paint is two years according to the relevant national standards.
6. Renovation
The thickness of the cold spray marking line is small, and it can be coated by covering or removing the original marking line. However, the hot-melt marking will not look good if it is covered again, so in many construction sites, the old line must be removed with a grinder before the new hot-melt marking can be reapplied.
7. Construction safety
Hot melt scribing construction will produce open fire to heat the coating, which is easy to cause safety hazards. Moreover, some ground and parking lot cannot withstand high temperature, and hot melt scribing machine is not convenient for construction. Cold spray marking paint is safer than normal temperature construction. In addition, the water-based pavement marking paint with water as the diluent has low taste, environmental protection, non combustion, non explosion and high safety. It also meets the environmental protection requirements of the project and reduces the impact on the health and life of constructors and users. It is a new type of environmental protection marking paint.
