2-trimethylsilyloxyethyl 2-methylprop-2-enoate - Introduction

2-(Trimethylsiloxy)ethyl methacrylate (STEGMA) is an organic silicon compound. It has the following properties:

1. Appearance: STEGMA is colorless or light yellow liquid.
2. Solubility: soluble in common organic solvents, such as alcohol, ketone and ether, insoluble in water.
3. Stability: Stable at room temperature, but not heat-resistant, not resistant to strong oxidizing substances such as acid and alkali.
4. Storage: should be stored in a dry, cool and well-ventilated place, avoid direct sunlight.

The main uses of STEGMA are as follows:

1. Polymer modifier: STEGMA can be used as a polymer crosslinking agent, plasticizer and modifier, which can improve the durability, impact resistance and aging resistance of polymers, and improve the physical properties of polymers.
2. Surface treatment agent: STEGMA can be used for the treatment of metal and non-metal surfaces to improve the coating adhesion and chemical resistance of objects.
3. Electronic materials: STEGMA can be used as packaging materials for electronic devices to improve the performance and stability of circuit boards.

Method:
The preparation of STEGMA is generally accomplished through a series of synthetic reactions. The specific steps include the reaction of silane and alkylene oxide, the ring-opening reaction of alkylene oxide and the esterification reaction catalyzed by base, etc. The specific operation needs to follow the laboratory safety regulations.

Safety Information:
1. STEGMA is safe and stable under regular conditions, but avoid contact with strong corrosive substances such as strong oxidants, acids and alkalis.
2. Use should wear appropriate protective equipment, such as gloves, goggles and laboratory coat.
3. Avoid inhalation, swallowing and contact with skin, avoid dust and gas.
4. Such as accidental contact, should immediately rinse with plenty of water, and medical treatment.
5. Store away from fire and heat sources and keep the container sealed.
