Store Below 5 ˚C DMS-R31: Methacryloxypropyl Terminated PDMS, 1,000 cSt (Telechelic Functional Fluid) Methacrylate and Acrylate functional siloxanes undergo the same reactions generally associated with methacrylates and acrylates, the most conspicuous being radical induced polymerization. Unlike vinylsiloxanes which are sluggish compared to their organic counterparts, methacrylate and acrylate siloxanes have similar reactivity to their organic counterparts. The principal applications of methacrylate functional siloxanes are as modifiers to organic systems. Upon radical induced polymerization, methacryloxypropyl terminated siloxanes by themselves only increase in viscosity. Copolymers with greater than 5 mole % methacrylate substitution crosslink to give non-flowable resins. Acrylate functional siloxanes cure greater than ten times as fast methacrylate functional siloxanes on exposure to UV in the presence of a photoinitiator such as ethylbenzoin. Oxygen is an inhibitor for methacrylate polymerization in general. The high oxygen permeability of siloxanes usually makes it necessary to blanket these materials with nitrogen or argon in order to obtain reasonable cures. DMS-R31 Properties

Datasheet Summary Powered by GS/AI
METHACRYLOXYPROPYL TERMINATED POLYDIMETHYLSILOXANE, 1,000 cSt (DMS-R31) is a liquid chemical intermediate classified as an organosiloxane. It is primarily used in applications involving radical-induced polymerization, where it behaves similarly to organic methacrylates and acrylates. The product has a viscosity of 1,000 cSt and a molecular weight of 25,000 g/mol, with a refractive index of 1.404.
This product is known to cause serious eye irritation and is suspected of reproductive toxicity. It is also harmful to aquatic life, both in acute and chronic scenarios. Proper handling precautions include wearing protective gear and avoiding contact with skin and eyes. Storage should be below 5°C and under nitrogen to prevent polymerization inhibition due to oxygen exposure.
Engineers considering this product should evaluate its suitability for their specific applications, particularly in systems requiring methacrylate functional siloxanes for modification or polymerization processes.
