(METHACRYLOXYMETHYL)BIS(TRIMETHYLSILOXY)METHYLSILANE - Introduction

(1,1,1,3,5,5,) methyl 2-methylprop-2-enoate, also known as MTMSA(Methyltris (methylacryloxy) silane) is a silane compound. The following is a description of its nature, use, preparation and safety information:

Nature:
-Appearance: colorless transparent liquid
-Molecular formula: C14H30O6Si3
-Molecular Weight: 390.64
-Density: 1.00g/cm³(20 ℃)
-Boiling point: 250 ℃
-Flash point: 144 ℃

Use:
- MTMSA is mainly used as a crosslinking agent for bismaleimide (BMI) resins, which can improve the thermal stability and chemical resistance of the resin.
-It can also be used as a crosslinking agent in emulsion polymerization, graft modification, coatings and inks to improve the wear resistance and high temperature resistance of the coating.
-due to the silane bond in the structure of methacryloyloxymethyl and BIS (trimethylsiloxy) methylsilane, MTMSA can also be used as a surface treatment agent for silica gel, modification of nanomaterials and glass fiber reinforced polymers.

Method:
MTMSA is usually prepared by first reacting methyl allyl alcohol with trimethylchlorosilane, and then reacting with triacetoxychlorosilane to obtain a product that is then condensed with trimethylethynylsilane.

Safety Information:
- MTMSA has no obvious toxicity and irritation under regular conditions of use.
-But as an organic silicon compound, avoid prolonged contact with skin and inhalation. Wear protective gloves and goggles when using.
-In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
-should be stored in a cool, dry, well-ventilated place, away from fire and oxidizing agents.
