Vinyltriethoxysilane Supplier Malaysia
- Also known as
- Triethoxyvinylsilane
- VTES
Vinyltriethoxysilane is an organofunctional silane used for polymer grafting, moisture crosslinking, mineral treatment and adhesion promotion. It combines a vinyl group with hydrolysable ethoxy groups and is commonly abbreviated as VTES.
Standard, high-purity and stabilised grades may be selected by assay, colour, water, acidity and storage requirements. The material is handled as a clear liquid and must be protected from moisture before controlled hydrolysis or grafting.
Applications include moisture-curable polyethylene, wire and cable compounds, mineral-filled plastics, treated fillers, coatings, adhesives, sealants and speciality organosilicon synthesis. Vinyltriethoxysilane remains separate from vinyltrimethoxysilane and amino or epoxy-functional silanes.

Vinyltriethoxysilane 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 |
|---|---|---|---|---|
| Standard vinyltriethoxysilane | clear liquid | Assay, colour, water, acidity and stabiliser condition confirmed against the application | Silane coupling and crosslinking component in polyethylene, mineral-filled polymers, adhesives and sealants. | Drum or IBC format is confirmed with the quotation. |
| High-purity vinyltriethoxysilane | clear low-colour liquid | Tighter purity, water and hydrolysable impurity controls matched to speciality synthesis | Electronic materials, coatings and controlled silane chemistry requiring lower contamination. | Sealed drum or smaller commercial packing is confirmed with the offer. |
| Stabilised VTES grade | clear stabilised liquid | Stabiliser and storage requirements specified for transport and processing | Moisture-crosslinkable polymer and grafting processes requiring defined storage stability. | Compatible sealed drum packing is confirmed with the quotation. |

Common questions about vinyltriethoxysilane
What is vinyltriethoxysilane used for?
VTES is used for polymer grafting, moisture crosslinking, filler treatment and adhesion promotion in polyethylene, composites, coatings, adhesives and sealants.
Is vinyltriethoxysilane the same as vinyltrimethoxysilane?
No. The ethoxy and methoxy silanes are separate products with different hydrolysis and processing behaviour, so the exact material must be specified.
Which polymer applications use VTES?
It is commonly evaluated for moisture-crosslinkable polyethylene, wire and cable compounds, mineral-filled polymers and compatible composite or adhesive systems.
Why are water and stabiliser controls important for VTES?
Moisture can initiate hydrolysis, while the stabiliser condition affects storage and processing. Buyers should state the accepted controls for their route.
What details are needed for a vinyltriethoxysilane quotation?
Send the application, grade, assay, water and stabiliser limits, required quantity, container preference and Malaysian delivery point.
