The differences between thermoplastic striping machines and cold paint striping machines, their application scenarios, and functions. #4

Thermoplastic and cold paint striping machines are two types of road marking equipment that utilize distinct types of paint and application processes suited for different work scenarios. Here are the main differences between the two and the methods each is best suited for:

Thermoplastic Striping Machine:

It uses a heating system to melt solid thermoplastic paint to about 200°C (392°F) before it is applied to the road surface through the machine’s nozzle.

The paint cools and solidifies rapidly, forming durable markings.

Features:

Highly durable, typically lasting 2-3 years or longer.

Thermoplastic markings are bright and have strong adhesion and resistance to wear.

Glass beads can be added to improve nighttime reflectivity.

Requires specialized equipment and operator training.

The working environment temperature must usually be above 10°C (50°F).

Suitable Work Scenarios:

Freeways and urban roads, especially those with heavy traffic and high vehicle speeds.

Areas where long-term markings are required, with infrequent changes to road markings.

Suitable for large-scale engineering projects due to higher equipment investment and project costs.

Cold Paint Striping Machine:

Working Principle:

An airless or air-assisted spraying system is used to apply cold paint (water- or solvent-based) directly to the road surface.

The paint dries naturally at ambient temperature.

Features：

Simple construction eliminates the need for heating equipment and reduces operator training requirements.

Fast drying time, suitable for rapid traffic marking updates.

Good flexibility, ideal for emergency or temporary marking work.

Durability is relatively lower than thermoplastic markings, typically lasting several months to a year.

Suitable Work Scenarios：

Parking lots, schools, and community roads with relatively light traffic.
Places that require frequent updates or temporary markings, such as temporary markings in construction zones.

In regions and seasons where the temperature is too low or weather conditions are unsuitable for thermoplastic paint application.

The choice between thermoplastic and cold paint striping machines should be based on the specific work scenario and needs. A thermoplastic striping machine is the better choice if long-lasting and wear-resistant markings are required and the budget allows. However, a cold paint striping machine may be more suitable if the work environment requires quick completion, changes frequently, or the budget is tight.
