Ureidopropyltrimethoxysilane

As a rust inhibitor for metal surfaces, it has special effects. When used to treat the surfaces of metals such as gold, silver and copper, it can improve their corrosion resistance, oxidation resistance and enhance their adhesion to polymer materials. It is widely used in filling polymer materials and can be applied to both thermosetting and thermoplastic polymer materials, such as epoxy, acrylonitrile, phenolic sulfonate, polyvinyl chloride, polystyrene, polycarbonate, etc. It is particularly effective in the rubber industry, which can enhance its mechanical properties, improve wear resistance, and reduce permanent deformation. It is suitable for NR, EPDM, SBR, polysulfide rubber, styrene-butadiene rubber, nitrile rubber, chloroprene rubber, and polyurethane rubber, etc. The range of inorganic fillers it is applicable to is also very wide, and it can be used for silicon-containing substances such as glass fiber, silica, quartz powder, talc, mica, fly ash clay, and kaolin.

Packaging and storage

📦 Packaging Specifications

Standard Industrial Packaging

200 kg/drum: Steel or plastic drums (common for bulk industrial supply).
20–25 kg/drum: Plastic buckets or cartons (e.g., 4 × 5 kg plastic buckets per carton).
Custom Bulk Options: IBC totes (1,000 L) for large-scale orders.

Small-Volume & Laboratory Packaging

1 kg: Aluminum foil bags with fluorinated bottles.
5–100 g: Sealed bottles or vials (e.g., 25 g, 100 g for R&D use).

Storage & Handling Requirements

Storage: Keep in a cool (2–8°C recommended), dry, and ventilated area; strictly avoid moisture (hygroscopic and hydrolyzes upon water contact).
Sealing: Containers must be tightly sealed under inert gas (nitrogen/argon) to prevent hydrolysis and self-polymerization.
Shelf Life: Up to 2 years when stored properly.

Safety Labeling

Hazard Symbols: Xi (Irritant).
Risk Phrases: H315 (Skin irritation), H318 (Serious eye damage), H335 (Respiratory irritation).
Precautionary Measures: Use gloves/eye protection; ensure adequate ventilation during handling.
