What is cold bituminous base mastic?

You certainly know that filling the expansion joints of concrete structures is one of the most important steps in the implementation of the structure. This will make the structural behavior consistent, and in addition, it will preserve the properties of concrete and make it leak impervious.

Therefore, one of the simple and affordable sealants in this regard is bituminous mastic with cold performance. In order to get more familiar with cold-applied mastic, we must say that this type of mastic is a type of single-component bituminous mastic, which consists of bitumen rubber, bitumen, special solvents and special chemical additives, as well as emulsion resins produced from the main components of cold-applied mastic. .

There are different types of cold-set mastic and many uses, and you can buy cold-set bituminous mastic online at a reasonable price from Iran's concrete clinic.

Benefits of cold mastic implementation

Among the advantages of cold-applied bituminous base mastic, we can mention each of the following:

• It is economically more affordable than other expansion joint fillers.
• Easier implementation than other similar items such as hot bituminous mastic
• The product is ready and does not need to be heated to become a liquid.
• With non-asbestos fibers to prevent falling during execution.

The mechanism of cold mastic effect

In the mechanism of the bitumen sealant effect with cold application, we should mention that this product is made of bitumen and emulsion resins, as well as special mineral powders, which causes high adhesion to all types of surfaces. This type of sealant will create a hard layer after applying and creating a cover and drying, which will create both the sealing and adhesive properties of bitumen and, in addition, the properties of emulsion resins.

Due to the presence of special compounds in the formulation of the production of cold bituminous mastic, it is very soft and malleable at the time of execution and can be easily poured or injected at the desired points.
