Which aspect does not affect the performance of resin used in fiberglass products?

The color of the resin does not affect the functional performance of the resin used in fiberglass products. While color may be important for aesthetic purposes or for branding, it does not influence the mechanical strength, chemical stability, thermal performance, or resistance to abrasion.

The mechanical strength of the resin impacts how well the fiberglass can withstand loads, the chemical and thermal performance determines its durability under various environmental conditions, and the resistance to abrasion is crucial for applications where the surface may experience wear and tear. These factors play a critical role in ensuring the overall functionality and longevity of fiberglass products, while the color merely serves a visual or marketing purpose.
