The general road marking paint applied on the asphalt pavement will not cause air bubbles, but some road marking paint will appear

air bubbles on the cement pavement. Today Qingdao Sainuo polyethylene wax manufacturer will show you the road marking paint

causes of bubbles.

1. Some manufacturers attribute the reason to the quality of “polyethylene wax”. Polyethylene wax, its composition is low

molecularweight polyethylene. Polyethylene itself is widely used because of its alkali resistance, excellent cold resistance, heat

resistance, chemical resistance and abrasion resistance. (Plastic drums are usually used in the market to contain alkaline substances).

2. One of the important substances in the raw materials for marking paint – Petroleum resin. Petroleum resin is named because it is

derived from petroleum derivatives. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance

and chemical resistance. It is chemically stable to acids and bases and has good viscosity and thermal stability. Petroleum resins are

generally not used alone, but as accelerators, regulators, modifiers and other resins.

It can be seen that neither polyethylene wax nor petroleum resin is the cause of bubbles

Regarding this situation, Qingdao Sainuo collected various data and found the following reasons:

1. The air in the gap between the roads is heated to produce bubbles

2. Wet ground will produce air bubbles;

3. If the primer is not dry, it will also generate bubbles;

4. Modified asphalt is prone to generate bubbles when heated;

5. Alkaline heavy cement pavement is prone to foaming;

6. There are many loose air bubbles on the cement pavement
