Platinum Catalyst Gel Curing System

PCSWIC is a two-component platinum-based gel curing system specifically formulated for the vulcanization of high-temperature silicone rubber (HTV).

This system consists of two parts — YA/220/WIC and YB/220/WIC — which must be used simultaneously under low-temperature conditions and a short curing cycle to achieve optimal performance.

Wire Iran Co. introduces a pioneering advancement in silicone technology: The first the platinum curing system, fully developed and manufactured in Iran.

Custom Formulations & Colors

Custom gel formulations and color matching available to meet specific application requirements.

Usage Instruction

The recommended concentration of each component and the curing conditions depend on the specific type of HTV silicone being used. These parameters are provided in the table below:

Platinum-Cure System

Concentration in mixing
Process	HTV based	A (Wt.%)	B (Wt.%)	Temperature (˚C)*	Time (min)*
Compression molding	PPT	0.8	1.5	100-150	4 <
Compression molding	Fumed	0.8	1.5	100-150	4 <
Extrusion	PPT	1.5	1	200-300	5 <
Extrusion	Fumed	1	1.5	200-300	5 <

Note: * The measure of temperature and time are depended on product’s thickness.
