ADDSiL™ 4009 — Epoxy-Functional Silane Adhesion Promoter

Product Overview

ADDSiL™ 4009 is an epoxy-functional adhesion promoter whose reactive groups can interact with a coating resin and an inorganic substrate. The supplied TDS describes improved interfacial bonding and support for wet adhesion and adhesion durability.

Key Features

• Promotes bonding between organic resins and inorganic substrates.
• Relevant substrates include glass, metals, ceramics and mineral surfaces.
• Can help improve wet adhesion and adhesion durability.
• Suitable for multiple coating resin systems.

Physical Properties

Selected values from the original TDS. Refer to that document for conditions and whether values are typical or specification limits.

Typical Applications

• Epoxy, polyurethane and acrylic coatings on glass, metal, ceramic and mineral substrates.

Technical Considerations

A typical starting level is 0.2–1.0% based on the total formulation. The product can generally be added directly; choose the stage according to the coating system and process. In water-containing or highly reactive systems, evaluate compatibility, pot life and storage stability. Determine the final dosage and addition procedure by preliminary testing.

The source reports a density value of 0.99 at 25°C without a unit; no unit has been inferred here. Other reported physical values are typical, not specifications. Keep sealed in a cool, dry, ventilated place; unopened shelf life is 12 months. Refer to the current SDS before handling.
