Brand: ZEMSIL

Question 1

What is ZEMSIL CS-151?

Accepted Answer

ZEMSIL CS-151 (Vinyltriethoxysilane (VTES), CAS 78-08-0) is a ZEMSIL® silicone material. ZEMSIL CS-151 (vinyltriethoxysilane) is the most widely used vinyl silane coupling agent, equivalent to KH-151 and A-151. Vinyl group enables radical and condensation reactions; three ethoxy groups provide silicone-surface bonding. Used as grafting agent for moisture-cure crosslinked polyethylene (XLPE) cable insulation and as adhesion promoter for polyolefins.

Question 2

What is ZEMSIL CS-151 equivalent to?

Accepted Answer

ZEMSIL CS-151 is equivalent to KH-151, A-151, Dynasylan VTEO and can be used as a direct drop-in replacement in most formulations.

Question 3

What are the main applications of ZEMSIL CS-151?

Accepted Answer

ZEMSIL CS-151 is used in: Moisture-cure XLPE cable insulation, Silicone rubber reinforcement, EVA crosslinking, Unsaturated polyester, PP/PE adhesion.

Question 4

What are the key specifications of ZEMSIL CS-151?

Accepted Answer

Purity (GC): ≥98 %; RI (20°C): 1.397–1.399; Density (25°C): 0.897–0.901 g/cm³; Flash Point: 37 °C; Color (APHA): ≤10; Moisture: ≤0.5 %; BP: 161 °C

Question 5

What is the CAS number of ZEMSIL CS-151?

Accepted Answer
