Key Features and Applications:

Corrosion Inhibitor for Metals:
Mercaptopropyl Trimethoxysilane is highly effective as a metal surface rust inhibitor. It can be used to treat metals like gold, silver, and copper to improve their corrosion resistance, antioxidant properties, and adhesion to polymers.

Polymer Filler Additive:
It is widely used in polymer materials as a filler additive, applicable to both thermosetting and thermoplastic materials such as epoxy, acrylic, phenolic, PVC, polystyrene, and polycarbonate. It enhances the mechanical and chemical properties of polymers.

Rubber Industry:
Particularly beneficial in the rubber industry, where it improves mechanical properties, wear resistance, and reduces permanent deformation. It is suitable for NR, EPDM, SBR, polysulfide rubber, butadiene rubber, nitrile rubber, chloroprene rubber, and polyurethane rubber.

Inorganic Filler Treatment:
It can be used for a wide range of inorganic fillers, including glass fibers, silica, quartz powder, talc, mica, and fly ash. It enhances the compatibility of these fillers with polymer matrices, improving their dispersion and mechanical properties.

Widely Used in Manufacturing:
Mercaptopropyl Trimethoxysilane is employed in a variety of industries, including rubber, plastics, fiberglass, coatings, adhesives, and sealants. It is used as a fiberglass treatment agent, crosslinking agent, and coupling agent.

Storage Instructions:

Store in a cool, dry place, away from moisture, direct sunlight, and heat.

Keep containers tightly sealed to prevent contamination and degradation.

Avoid exposure to air and moisture to maintain stability.

Packaging Options:

Available in 200 kg drum, or custom packaging upon request.

Safety and Handling:

Handle with care and always use appropriate personal protective equipment (PPE), such as gloves, goggles, and lab coats.

In case of skin or eye contact, rinse immediately with plenty of water and seek medical attention if irritation persists.

Consult the Safety Data Sheet (SDS) for detailed handling, storage, and disposal instructions.
