PVDF contains 30% acrylic and 70% polyvinylidene thermoplastic fluoropolymer. PVDF resin is highly protective and resists UV rays, humidity, sun’s heat, and pollutants in the air. It is the most commonly chosen paint system for a metal roof with a standing seam.
SMP, also known as silicone-modified polyester, is another paint system for coating metal coil products and metal sheets. It also combines silicon (to retain gloss) and polyester (to ensure weather resistance).
The PVDF paint system has a high color retention capacity, which is better than other common coatings.
Moreover, the whitish residue, known as chalking, becomes visible on the metal surface due to pollution, water, and chemicals. But PVDF doesn’t show fading and chalking so you can save cost on repair or paint.
This coating will last for several years without showing degradation signs.
Good warranty coverage and fade resistance are other reasons for investing in the PVDF paint system.
The SMP paint system is advantageous because of its scratch resistance.
SMP coating formulas have become more advanced. Thus, you will find more applications for this paint system. SMP is the right choice for those who desire textured finishes for their metal roof surfaces.
Another reason for choosing SMP coating is that it is available at a highly reasonable rate. Due to this low cost, it is highly useful for agricultural and structural metal roofing projects.
