Our Advantages

 

 

In which applications is polyester resin commonly used?
Polyester resin is used in:

• Marine and automotive industries for fiberglass-reinforced products
• Construction for composite materials and coatings
• Consumer goods for making synthetic marble and castings
• Coatings for appliances and architectural materials

What safety precautions should be taken when handling polyester resin?

• Personal Protective Equipment (PPE): Wear gloves, masks, and protective clothing.
• Ventilation: Ensure good ventilation in the workspace to avoid inhalation of fumes.
• Avoid Skin Contact: Polyester resin can cause skin irritation; wash thoroughly after handling.

How should polyester resin be stored?

Store polyester resin in a cool, dry place away from direct sunlight and heat sources. Keep containers tightly sealed to prevent contamination and evaporation of volatile components.

What are the environmental considerations of using polyester resin?

Polyester resin can emit volatile organic compounds (VOCs) during the curing process, which can impact air quality. Proper ventilation and handling procedures are essential to minimize environmental impact. Additionally, disposal of resin and related waste should follow local regulations to avoid environmental contamination.

Can polyester resin be used for outdoor applications?

Yes, polyester resin can be used for outdoor applications, particularly when combined with UV inhibitors and other additives to enhance weather resistance. However, prolonged exposure to sunlight can cause some degradation over time without these additives.
