Silicone-Modified Polyester Coatings

UNICHEM offers advanced silicone-modified polyester coatings for coil-applied metal substrates, designed to provide exceptional heat and UV resistance, superior chemical protection, and enhanced durability—all without the use of fluoropolymers.

Silicone-Modified Polyester (SMP) Coatings for Durable, Eco-Friendly Metal Protection


These coatings are ideal for industries that require robust, long-lasting finishes and environmentally responsible solutions.

What Are SMP Coatings?


Silicone-modified polyester (SMP) coatings are hybrid formulations combining silicone and polyester polymers. This blend is optimized for demanding applications where exposure to heat, UV rays, and harsh chemicals is common. As industries increasingly shift away from fluoropolymer coatings due to environmental concerns, SMP coil coatings have emerged as a reliable and eco-friendly alternative.

Our expertise in developing coil-applied coatings ensures consistency and reliability for large-scale production, positioning us as a trusted partner in the industrial coatings sector.

Key Properties and Benefits of SMP Coatings


Silicone-protected polyester coil coatings offer many benefits that ensure long-lasting durability. Some of the most beneficial properties of SMP coil coatings include:

UV and Weather Resistance

  • SMP coil coatings provide outstanding UV resistance, preventing fading and chalking even with prolonged outdoor exposure.
  • The silicone component enhances weathering performance, helping maintain color consistency and gloss, making silicone-modified polyester coatings ideal for metal surfaces exposed to the elements.

Chemical and Solvent Resistance

  • Chemical resistant silicone coatings are engineered for environments where chemical exposure is a concern. SMP coatings offer exceptional resistance to oils, solvents, and corrosive agents, ensuring a robust and long-lasting barrier.
  • This resistance ensures that metal substrates remain protected, reducing the risk of degradation and preserving the coating’s integrity.

Heat Resistance and Thermal Stability

  • SMP coatings stand out for their high-heat resistance, suitable for applications such as exterior appliance panels and automotive parts where sustained exposure to high temperatures is expected.
  • The silicone modification in high-heat resistant coil coatings contributes to thermal stability, ensuring that coatings remain effective and intact under fluctuating temperature conditions.

Scratch and Abrasion Resistance

  • SMP durable coatings offer enhanced scratch and abrasion resistance, making them ideal for products that undergo regular handling, assembly, or transport.
  • These coatings protect against scuffs and scratches, reducing the need for frequent maintenance and ensuring a long-lasting finish.

Environmental Benefits: A Safe Alternative to Fluoropolymers


SMP coil coatings are an eco-friendly option, offering similar protective qualities to traditional fluoropolymer coatings but without the environmental hazards associated with PFAS. Silicone, derived from silica (sand), is non-toxic and poses no risk when it breaks down, unlike fluoropolymers that release harmful compounds over time.

Applications and Industries Served by SMP Coatings


Silicone modified polyester coatings are widely used in many applications and industries for their durable properties.

Appliances and HVAC

  • Silicone modified polyester coatings are widely used for appliance exteriors such as washers, dryers, and ovens, where they provide heat resistance, chemical protection, and lasting aesthetic appeal.
  • HVAC units benefit from SMP coatings due to their durability and ability to withstand harsh environmental conditions, maintaining their appearance and functionality.

Construction and Building Materials

  • Doors, Windows, and Garage Doors: SMP coatings are applied to metal doors and window frames to ensure scratch resistance, UV protection, and lasting durability.
  • Architectural Panels: These coatings are perfect for exterior architectural panels that need to withstand prolonged exposure to sunlight and environmental elements.

Transportation and Consumer Goods

  • Automotive and Trailer Panels: SMP coatings provide critical protection for automotive exteriors, offering resistance to road debris, chemicals, and weather elements.
  • Outdoor Furniture and Equipment: SMP coatings ensure that outdoor furniture retains its color and structural integrity, even when exposed to moisture and UV rays.

Coil Coating Application Techniques


UNICHEM’s SMP coatings are applied using the coil coating process, which guarantees uniform coverage and strong adhesion to metal substrates. This continuous process involves cleaning and pre-treating the metal surface, applying the coating, and curing it efficiently, resulting in a consistent and durable finish.

The coil coating process allows for quick curing times, reducing energy consumption and production downtime. This method not only enhances the bond between the coating and the substrate but also ensures a smooth, defect-free application across large-scale production.

Benefits of UNICHEM’s Silicone-Modified Polyester Coatings


Silicone-protected polyester coil coatings offer important benefits to manufacturers and end users.
