Molecular Formula | HO-Si(CH3)2O{Si(CH3)2O}n Si(CH3)2-OH | |
Feature and advantages:
Hydroxy silicone oil: Colorless transparent liquid with excellent electrical insulating properties and resistance to high
temperature, high flash point, low freezing point, long-term used -50ºC ~ +250ºC conditions, low the viscosity-temperature
coefficient, high compression ratio, low surface tension, hydrophobic moisture resistance, chemical inertness, physiologically
inertness.
Features
Hydroxy silicone oil is made by polymerization of siloxane monomers, the molecular silicone materials have hydroxyl groups at both
ends. The structural formula is as follows:
HO-Si (CH3) 2 O [Si (CH3) 2 O] n Si(CH3)2-OH
Chemical name is a, w- dihydroxy polydimethylsiloxane, it name 107 silicone rubber when the viscosity is above 2500mPa.S. In
addition to the general performance of methyl silicone oil, it also has reactive hydroxyl groups, it can be made available some
new material or crosslinked into elastomers (or membrane) .
Colorless transparent liquid with excellent electrical insulating properties and resistance to high temperature, high flash point,
low freezing point, long-term used -50 º C ~ +250 º C conditions, low the viscosity-temperature coefficient, high compression
ratio, low surface tension, hydrophobic moisture resistance, chemical inertness, physiologically inertness.
Specifications:
Appearance : colorless transparent liquid.
Viscosity (25ºC, mpa.s): 25~100000 (can be customized according to user requirements ).
Hydroxyl content (%): 0.5 - 3 (related to the viscosity).
Use:
Depending on the hydroxyl content and viscosity, respectively for different industries .
1. the medium-high viscosity of the product can be used as a paper –based of anti- adhesive agent, the cured film has excellent
anti-sticking effect, such as the label backing paper , asphalt wrapping, sealing tape base paper, decor paper end paper
processing.
2. in the electrical power industry as the main component insulating paint or a component of the insulator.
3. Used as a condensation-type RTV silicone rubber based adhesive and diluted material, such as sealants and plastic mold base
material.
4. Alter dimethyl silicone oil, and easy to emulsify .
5. Small molecule hydroxyl silicone oil (25 ~ 30CP, hydroxyl content of about 8%) is an excellent control agent of silicone
rubber, it not only simplifies the process of silicone rubber to improve the processing performance ( reduce heat treatment ) but
also increased the transparency of products, improved working conditions, when we use it to alter dihydroxy diphenyl silane .
6. New development applications.
Dosage:
Usually with the curing agent to achieve the crosslinking, it must be fixed by means of a coupling agent for the release paper,
generally the curing agent is about 3 to 5% of gum base, the coupling agent is about 0.5 to 1 % of gum base.
In most cases the solvent was diluted with 10 times the first gum base, then add the coupling agent and the curing agent after
mixing uniformly coated on the substrate surface at room temperature or heat curing. It need over 30 minutes at room temperature,
and 30 seconds for 120 ~ 150 º C. there is no need any solvents for sealants and molds for rubber, add the curing agent and stir (
one-component and two-component curing agent is used is not the same ) , after 30 to 120 minutes degassing it can be cured .
Note:
Hydroxy silicone oil can not be mixed with high temperature water vapor, acid/alkali substances, alkoxysilanes, otherwise there is
a tendency curing and viscosity changes.
