- IOTA-590 3-Mercaptopropyltrimethoxysilane
Molecular construction: HS(CH2)3Si(OCH3)3
Introduction:
3-Mercaptopropyltrimethoxysilane is a water-white to light straw liquid. It is a mercapto-functional silane that finds use as a coupling agent in polysulfide and polyurethane caulks and sealants.
It is especially useful in sulfur-cured and metal oxide-cured elastomers. Chemically bonding reinforcing minerals like silica, clay, mica and talc to the polymer matrix, properties including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time are improved in mineral-filled elastomers.
It can be used as a pretreatment on minerals or added at the time of compounding. Being a rather efficient and fast sulfur containing silane, typically lower silane loading levels are used.
Physical Properties:
Chemical Name: gamma-Mercaptopropyltrimethoxysilane
Formula: C6H16O3SSi
Molecular Weight: 196.4
Boiling Point: 93℃(5.3 KPa)
Refractive Index: 1.4400 (25℃)
Density 25℃: 1.040
Flash point: 48℃
Purity: Min 97.0%
CAS No.: 4420-74-0
EINECS No.: 224-588-5
Solubility:
3-Mercaptopropyltrimethoxysilane silane is soluble in methanol, ethanol, isopropanol, mineral spirits, acetone, benzene, toluene, xylene, and in water when suitable hydrolysis procedures are followed.
Applications:
Improved or equal performance is low-rolling resistance silica reinforced tread compounds can be achieved at lower silane loading levels when 3-Mercaptopropyltrimethoxysilane is substituted for commonly used polysulfide type silanes. Mineral-reinforced articles such as shoe soles, rubber rollers and wheels, white sidewalls, and wire and cure accelerator systems and increased sulfur-donor concentrations may be necessary when 3-Mercaptopropyltrimethoxysilane is substituted for slower cure-rate polysulfide-type silanes.
Packaging and storage:
1. This product is stable under normal temperature and pressure, avoid contact with open flame and high temperature, stored in a cool, dry and well ventilated warehouse, away from the fire, heat source. Keep container seal. The storage area should be equipped with a leak emergency treatment equipment and a good shelter material.
2. This product has slight irritation to skin, eyes and respiratory tract, so it should be well protected when using.
3. Packing: 200KG plastic barrel packaging.
