Monohydroxy terminated polysiloxanes

Electronic


Modifier OH 650 and 655 are mono-hydroxy-terminated polydimethyl siloxanes which are used as reactive plasticizers in condensation-curing silicones.
Due to the monofunctional structure, only one chain end of the Modifier OH reacts with the network, therefore it can not bleed out. The other loose end acts as a plasticizer: Modulus and hardness are reduced.


product overview:

  • Modifier OH 650

    Modifier OH are reactive silicone plasticizers for condensation systems containing both crosslinkable (hydroxy-functional) and unreactive chain ends. Modifier OH are therefore particularly suited for producing “non-bleeding” silicone sealants for marble/natural stone applications and for the electronics industry. Gel-like materials can also be produced using Modifier OH.
