DPM-0815J Silicone oil dispersant

Overview

• DPM-0815J is a monomeric alkoxy polysiloxane that absorbs moisture from materials or air to form silanol groups, which chemically bond with hydroxyl groups on inorganic surfaces, thereby achieving coating and modification of these surfaces. The long-chain polysiloxane at the other end enhances compatibility with silicone systems, ensuring excellent dispersion performance. It is primarily used to modify inorganic fillers by modifying their surface hydroxyl groups, improving powder dispersibility and filling efficiency while reducing system viscosity.

Product Features

• Single-end alkoxy-modified polysiloxane
• The surface of inorganic fillers can be modified by treating its surface hydroxyl groups.
• Improve compatibility and dispersion performance
• Significantly reduces the viscosity of the system while enhancing fluidity and wettability.
• Increase the powder filling amount

Application Area

• It can be applied in industries such as surface treatment of thermally conductive silicone, precipitated silicone rubber, spherical alumina, and precipitated silica.
• Usage method: Mix the additive uniformly with inorganic fillers (alumina, silica, etc.) or all base materials (additive, inorganic fillers, silicone oil) to form a homogeneous slurry. Let it stand for more than 2 hours (preferably overnight) to allow full reaction between the additives and the hydroxyl groups on the surface of the inorganic fillers, then stir again until thoroughly mixed.

Safety, Packaging and Storage

• Store unopened in a cool, well-ventilated place at room temperature, away from direct sunlight, and within the original packaging. The shelf life is 18 months from the date of production.
• Packaged in a 25KG plastic barrel.
