Question 1

What is ZEMSIL CS-540?

Accepted Answer

ZEMSIL CS-540 (N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane, CAS 1760-24-3) is a ZEMSIL® silicone material. ZEMSIL CS-540 is a diamine-functional silane equivalent to KH-792 and A-1120. The diamine structure provides higher reactivity with epoxy resins and stronger coupling efficiency compared to CS-550. Used in glass fiber composites, epoxy formulations requiring accelerated cure, and as surface treatment for fillers in polyamide systems.

Question 2

What is ZEMSIL CS-540 equivalent to?

Accepted Answer

ZEMSIL CS-540 is equivalent to KH-792, A-1120, Dynasylan DAMO and can be used as a direct drop-in replacement in most formulations.

Question 3

What are the main applications of ZEMSIL CS-540?

Accepted Answer

ZEMSIL CS-540 is used in: Epoxy Composites, Polyamide Adhesives, Surface Treatment of Fillers, Crosslinking Agent.

Question 4

What are the key specifications of ZEMSIL CS-540?

Accepted Answer

Purity (GC): ≥97 %; Refractive Index (20°C): 1.443–1.447; Density (25°C): 1.025–1.030 g/cm³; Flash Point: 107 °C; Color (APHA): ≤20

Question 5

What is the CAS number of ZEMSIL CS-540?

Accepted Answer

The CAS number of ZEMSIL CS-540 (N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane) is 1760-24-3.
