Product Description
Silaplane® FM-4421 is a reactive polydimethylsiloxane (PDMS) based polymer with a molecular weight of 5,000 g/mol and a Viscosity of 100 - 125 mPas. This reactive silicone material offers the addition of silicone-type properties to non-Silicone materials in a variety of industries including electronics, semiconductors, automotive, biotech, healthcare, and clean energy applications. It offers narrow polydispersity and a low level of chemical impurities.
Silaplane® FM-4421 bi-terminal product has two Hydroxy functional groups that are reactive toward a variety of compounds and surfaces enabling chemical and physical changes to chemicals, particle surfaces and larger surface structures. Hydroxy groups are mainly reactive with urethane and ester compounds.
