Does tile adhesive contain formaldehyde?

In fact, many things used in households now contain formaldehyde, but because the formaldehyde content in some of them is not that high, it will not cause any harm to the human body. However, substances such as tile adhesive are still needed. After all, some of the chemical components it contains can still cause some harm to people's bodies. So after decoration, try to avoid moving in at the beginning.

The main raw materials of tile adhesive: cement, quartz sand, heavy calcium, HPMC (hydroxypropyl methylcellulose), glue powder, wood fiber, starch ether

It is a high molecular polymer modified cement-based tile paste mortar.

Basically, it does not contain any ingredients. Even if there are any, they can be almost ignored unless the raw materials themselves are of substandard quality.

Tile adhesive contains a variety of additives, specifically the functionality of the tile adhesive. Generally, cellulose ethers are added to tile adhesives to provide water retention and thickening effects, as well as latex powders to increase the adhesion of tile adhesives. The most common latex powders are vinyl acetate/vinyl ester copolymers, vinyl laurate/ethylene/vinyl chloride copolymers, acrylic acid and other additives. The addition of latex powder can greatly increase the flexibility of tile adhesives, improve stress effects, and increase flexibility. In addition, other types of additives are added to tile adhesives with special functional requirements. For example, adding wood fiber can improve the mortar's resistance to cracking and increase the opening time, adding modified starch ether to provide the mortar with anti-slip properties, adding early strength agents to make the tile adhesive increase its strength faster, adding water repellents to reduce water absorption and provide waterproofing, etc.

The ratio of powder: water is 1:0.25-0.3. Stir evenly and then start construction; within the time allowed by the operation, the position of the tiles can be adjusted. After the adhesive is completely dry (caulking work can be carried out after about 24 hours, and heavy loads should be avoided on the tile surface within 24 hours of construction).

Tile adhesive, also known as ceramic tile adhesive, is mainly used to stick ceramic tiles, facing tiles, floor tiles and other decorative materials. It is widely used in finishing and decoration places of interior and exterior walls, floors, bathrooms, kitchens and other buildings. Its main characteristics are high bonding strength, water resistance, freeze-thaw resistance, good aging resistance and easy construction. It is an ideal bonding material.
