1. In addition to using high-quality UV resistant film and high-quality resin, the production curing degree of good daylighting panels is also an important factor. After testing, the curing degree of the FRP daylighting board of Chengdu Apenite is above 95%; The internal molecular structure is an approximately uniform network structure, which is very stable and difficult to be greatly affected by external factors such as ultraviolet radiation, water vapor, and acidic and alkaline substances. After the curing degree of the daylighting board increases, its hardness and mechanical strength (tensile strength, bending strength, etc.) will also be high, while exhibiting relatively brittleness.

2. As a building material, daylighting panels must first have a certain degree of stiffness and bending strength to ensure minimal deformation under external forces. In this way, it can avoid the failure of sealant and waterproof treatment due to external forces, effectively preventing water leakage.

3. Many domestic daylighting panels have added a plasticizer (i.e. softener) substance to the daylighting panels in order to increase their toughness. This substance can make the skylight board very flexible, but it will have a significant impact on its strength. And after a period of time, it will float on the surface of the skylight and precipitate, which is also a high carcinogen. It has been strictly prohibited in foreign countries, especially in EU countries. Moreover, after adding plasticizers (softeners), the aging resistance and lifespan of the daylighting board will be greatly reduced, which is equivalent to drinking poison to quench thirst. Eponite refused to add these substances out of a responsible attitude towards customers.

4. As a steel structural accessory, the daylighting panel is strictly prohibited from being stepped on. During the transportation and lifting process on the roof, the daylighting panel will not be damaged by the correct operation method and normal bending and deformation of the daylighting panel. Our company has provided corresponding explanations for this.

Overall, the brittleness of the daylighting board is a manifestation of its excellent comprehensive performance. As long as there are no significant cracks during normal operation, it will not have any impact on its normal use. Please feel free to use it.
