heat reflective roof tiles

The prerequisite of color steel plate aging or photochemical reaction is that the surface composition of SMARTROOF METAL ROOF SHEET can absorb radiation. When the radiation absorbed by the molecular structure is greater than the bond energy of the molecular structure, the coating can be dissolved, because the less wavelength of the light source, the more kinetic energy it contains. The brittleness of color steel plate in air pollution is the kinetic energy of ultraviolet band in natural light, which is higher than the bond energy of molecular structure.

As the polyurethane coating ages, the substrate itself is gradually missing, and the coating surface becomes smooth and loses light. The loss of this substrate leaves a more stable color paste, which in the non-viscous powder form leaves a polyurethane coated surface layer, a process known as delamination. SMARTROOF METAL ROOF SHEET thick coating polyester steel coil aging performance varies greatly, thick coating color sheet aging resistance is stronger.

Therefore, the above is the reason for the aging of SMARTROOF METAL ROOF SHEET. You should know that any product can achieve good results only in accordance with the correct operation method. So for the product must be correctly installed and used and do a good job of late maintenance work can effectively extend the service life, reduce the aging may oh.
