The use of polyurethane sealants in the construction and automotive industries must be carried out with correct technical and safety precautions. Incorrect application can both reduce product performance and pose risks to the user. This article will detail the safety tips to consider when applying sealant.

1. Use of Personal Protective Equipment (PPE)

Gloves, protective goggles, and a mask (if necessary) must be used when applying sealant.
Contact with mastic may cause allergic reactions in sensitive skin.
To protect the respiratory tract during use, masks should be preferred, especially in enclosed spaces.

2. Ventilation

Good ventilation should be ensured when applying mastic in enclosed spaces.
This prevents the inhalation of solvent vapors and creates a healthy working environment.
Particular attention should be paid to in-vehicle applications in the automotive sector.

3. Preparation of the Application Area

Surface cleaning and drying are essential steps in ensuring a safe application.
Sealant will not bond to damp or dirty surfaces, increasing the risk of overflow and leakage.
Joint or gap preparation must be done correctly.

4. Storage and Storage Security

Mastic products should be stored in a cool, dry place, out of reach of children.
Open or damaged packaging should not be used.
Sealant exposed to high temperatures or direct sunlight may lose its safe service life.

5. Points to Consider During Application

Insert the sealant tube or cartridge correctly and apply pressure in a controlled manner.
Avoid environmental factors such as wind or dust in open areas.
In case of contact with eyes or skin, rinse immediately with plenty of water.

6. Safety Recommendations in the Construction Sector

Limit the area where mastic can be applied on construction sites and keep workers informed.
When working at height, use appropriate platforms and safety equipment.
Take precautions on surfaces that may come into contact with chemicals.

7. Safety Recommendations in the Automotive Industry

Adequate ventilation must be provided during mastic application on production lines.
Use respiratory protective equipment in enclosed vehicle cabins.
Exercise caution when handling and placing sealant tubes; avoid impacts and pressure.

8. Emergency Measures

In case of eye contact, rinse thoroughly with water and seek medical attention if necessary.
If skin irritation occurs, cleanse the skin and apply a protective cream.
If swallowed, seek medical attention and show the packaging information.
