SMP (Silicone-Modified Polyester) paint systems are developed using a blend of polyester and silicone agents.  Silicone acts to improve the gloss retention and weather resistance of the polyester coating.  As a rule, the higher the silicone content, the better the performance of the paint.

SMP pre-painted steel has been used in the construction industry for decades and is preferred by many building owners due to the relative durability of the coating and the budget-friendly cost as compared to other more expensive paint systems. SMP paint systems typically come with a standard 40-year limited warranty but the length and what is covered may vary by paint manufacturer.


Durability – typically more resistant to rough handling as compared to PVDF

Lower Cost – compared to PVDF systems, the cost is usually less for SMPs

Chalk & Fade Resistance – performs better than standard polyester systems
