What are the specific aspects of weather resistance of acrylic resin materials?

The core of weatherability of acrylic resin lies in its long-term resistance to natural factors such as light, heat, water and oxygen, which can effectively delay the aging of materials and maintain stable performance, which is also the key advantage that distinguishes it from many other resins.

1. Excellent resistance to ultraviolet (UV) degradation.

This is the core embodiment of its weather resistance.

The molecular structure is stable, and it does not contain groups such as double bonds or benzene rings that are easily damaged by ultraviolet rays, which can reduce the molecular chain breakage caused by ultraviolet rays.

Long-term exposure to the sun is not easy to cause yellowing, brittleness, cracking and other problems, especially suitable for outdoor use scenes.

2. Good heat resistance and low temperature stability

It can adapt to a wide range of temperature fluctuations and maintain physical properties.

High temperature resistance: it is not easy to soften, deform or stick in high temperature environment in summer, and maintains the appearance and structural integrity of coating or products.

Low temperature resistance: in low temperature environment, it is not easy to harden, embrittle or peel off, and it can still maintain a certain flexibility.

3. Excellent water and humidity resistance

It can resist the influence of rain, dew and humid environment.

It is difficult for water molecules to penetrate into the resin, which can reduce the expansion, foaming or performance degradation caused by water absorption.

In high humidity environment, it is not easy to breed mold, and it is not easy to degrade by chemical reaction with water.

4. Strong oxygen resistance and atmospheric corrosion resistance

Can resist the erosion of oxygen and pollutants in the air.

Strong oxidation resistance, not easy to age due to oxidation reaction with oxygen, and prolong the service life of the material.

It has certain tolerance to dust, acid rain and other pollutants in the air, reducing its corrosion and pollution to the surface of materials.
