Expanding Dow’s Expertise in Novel SMP Polymers

Polydimethylsiloxane (PDMS)-based sealants are widely recognized for their outstanding durability, flexibility, and resistance to environmental stress, making them a trusted choice for demanding applications. Silicones excel in long-term performance, particularly in extreme environments, due to their exceptional weathering resistance and elasticity. However, evolving requirements—such as paintability—have driven increased interest in hybrid technologies that complement silicone’s strengths.

Silane-modified polymer (SMP) sealants address these needs while preserving many benefits associated with the silicone chemistry set. SMP technology leverages the reactive advantages of silane chemistry to deliver versatile adhesion and paintability, enabling it to work alongside silicone sealants rather than replace them. Dow’s patented SMP polymers represent a significant advancement in this technology space, offering fast cure speed and low tack development compared to conventional SMP systems.

This presentation will deliver a comprehensive overview of Dow SMP polymers, detailing their underlying chemistry and performance characteristics. The discussion will emphasize innovative polymer developments that advance cure speed and enable a broader spectrum of physical property optimization. Further tunability can be achieved by TMS converters thereby providing specific functionalities that enable customized properties.
With expertise in both silicone and SMP technologies, Dow collaborates with industry partners to enable informed product selection and complementary solutions, expanding our portfolio with novel materials that unlock new possibilities for evolving application needs.
