Hydrogenated MQ resin is a kind of organic silicon polymer material with special structure and performance. The following is a detailed introduction to it:
1. Chemical structure
Hydrogenated MQ resin is prepared by a specific chemical reaction. Its molecular structure contains tetrafunctional siloxane chain segments (Q) and monofunctional siloxane chain segments (M). At the same time, some R groups are replaced by hydrogen atoms, hence the name hydrogenated MQ resin. This special structure gives hydrogenated MQ resin unique performance and application value.
2. Performance characteristics
Reactivity: Due to the presence of silicon-hydrogen bonds in the molecular structure, hydrogenated MQ resin has high reactivity and can participate in a variety of chemical reactions, such as silicon hydrogen addition reaction.
Crosslinking: Hydrogenated MQ resin has excellent crosslinking properties and can undergo crosslinking reactions with other compounds containing active functional groups to form a stable crosslinked network structure.
Heat resistance: The resin has good heat resistance and can maintain stable performance under high temperature environment.
Weather resistance: Hydrogenated MQ resin has good resistance to environmental factors such as ultraviolet rays and ozone, and is not easily degraded by environmental factors.
3.Application fields
Hydrogen-containing MQ resin is widely used in various fields, such as silicone pressure-sensitive adhesive, building sealant, organic resin coating, etc. as a tackifier, and can also be used to make mobile phone buttons, epoxy adhesive bonding surfaces, etc. In addition, it can also be used as a reinforcing agent in addition-type liquid silicone rubber. The reinforced silicone rubber is colorless, transparent and has high mechanical strength.
In summary, hydrogen-containing MQ resin is a silicone polymer material with special structure and properties. Its reactivity, cross-linking, heat resistance and weather resistance make it have broad application prospects in many fields.
