Plasticizers

Plasticizers for silicone-based sealant and adhesive formulations adjust the viscosity, allowing easier application and extrusion of the final formulation. Silicone plasticizers can soften cured materials by increasing elongation and reducing modulus.

Solvent

Cyclotetrasiloxane is a volatile methylsiloxane fluid, that is clear, odorless, has low toxicity, low surface tension; and evaporates completely at room temperature. This solvent helps the delivery of silicone sealants and coatings before evaporating completely.

Hybrid Polymer

Utilize hybrid polymers to experience the benefits of silane reactivity while maintaining paintability and strength. Hybrids are differentiated by their distinct polymer structure where organic polymer backbones are functionalized with silanes. Structure types are silane-terminated polyurethane structures and silane-terminated polyether structures. Innovation in the polymer structure has advanced over time, and this innovation has helped hybrid formulations expand to new applications. Whether you are looking to develop a robust general-purpose adhesive or differentiate with distinct properties, Dow has you covered.

Dow is an integrated supplier of polyether polyol and MDI with operations around the world for global supply. Our regional technical support and variety of distribution partners can help make sure your unique adhesive and sealant formulation needs are met.

Dow polyether polyols include:

  • Standard diol and triol building blocks
  • Low monol polyols to improve tensile strength and elongation
  • EO-capped polyols to enhance reactivity and hydrophilicity
  • Hydrophobic polyols offer water resistance
  • High functional polyols to achieve greater rigidity
  • Amine-initiated polyols for catalytic behavior to potentially reduce catalyst loading


The isocyanate portfolio complements these polyols with a variety of monomeric, polymeric, and modified MDI grades.

Off-the-shelf MDI-based prepolymers are also available as intermediates for a one-component formulation with additives or as one part of a two-component solution. Our prepolymer manufacturing capabilities are flexible to expand our offering as your needs evolve.
