Tetraethyl Orthosilicate (TEOS) Supplier in Malaysia
- Also known as
- TEOS
- Tetraethoxysilane
- C8H20O4Si
Tetraethyl orthosilicate supplier in Malaysia for semiconductor, photovoltaic, coatings, construction-material and laboratory buyers sourcing a liquid silica precursor. Also known as tetraethoxysilane or TEOS, it undergoes controlled hydrolysis and condensation to form silica-rich materials and networks.
Industrial grade serves sol-gel coatings, binders, ceramics and speciality material production, while reagent grade supports laboratory synthesis. High-purity electronics grade is selected where water and trace-metal limits matter in silicon-dioxide deposition or related processes.
Buyers commonly compare assay, water, acidity, colour, density, refractive index and trace-metal controls. This page covers neat tetraethyl orthosilicate rather than pre-hydrolysed ethyl silicate binders or formulated sol-gel products.
Send the required grade, purity specification, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Tetraethyl Orthosilicate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Industrial-grade tetraethyl orthosilicate | clear liquid | — | Sol-gel silica preparation, coatings, binders and speciality-material manufacture where assay, water and acidity are set by the process. | Pack format is confirmed with the quotation. |
| High-purity electronics-grade TEOS | high-purity clear liquid | — | Silicon-dioxide deposition and related semiconductor or photovoltaic processes that require tightly controlled trace metals and water. | Pack format is confirmed with the quotation. |
| Reagent-grade tetraethyl orthosilicate | clear liquid | — | Laboratory sol-gel work, silica synthesis and materials development where the buyer specifies analytical purity and hydrolysis behaviour. | Pack format is confirmed with the quotation. |

Safety and handling
Keep tightly closed in a cool, dry and well-ventilated place away from heat, moisture and incompatible materials. Protect from water contamination and follow the handling information for the quoted grade.
Common questions about tetraethyl orthosilicate
Is tetraethyl orthosilicate the same as TEOS or tetraethoxysilane?
Yes. TEOS is the common abbreviation, and tetraethoxysilane is an alternate chemical name for tetraethyl orthosilicate. A buyer should still state the grade and impurity specification because the same identity is sold for industrial, laboratory and electronics processes.
Which TEOS grade should a buyer request?
Industrial grade suits coatings, binders and general sol-gel manufacture. Reagent grade addresses laboratory work, while electronics grade requires tighter water and trace-metal controls for deposition processes.
Why is water control important for tetraethyl orthosilicate?
TEOS reacts with water during hydrolysis and then condenses towards a silica-based network. Unplanned moisture can change storage stability and process behaviour, so the enquiry should state the required water limit and the receiving process should control hydrolysis conditions.
Is ethyl silicate always the same as pure TEOS?
Not necessarily. Ethyl silicate can be used broadly for TEOS or for hydrolysed and oligomeric binder products. If the process needs neat TEOS, identify the CAS, assay and water specification rather than relying on the broad trade term alone.
Which specifications matter for electronics-grade TEOS?
State assay, water, acidity and the required limits for named trace metals or other process impurities. Include the deposition or photovoltaic process context so the quoted purity profile can be reviewed.
What details are needed for a TEOS quotation in Malaysia?
Send the grade, application, assay and impurity specification, quantity, preferred packing, required product documents and delivery location. Available packing, documentation and timing are confirmed with the quotation.
