FAQ  for Platinum Catalyst

What is the minimum cure temperature?

Can cure at room temperature (25°C), though 40–60°C is recommended for faster cycles.

Is it suitable for potting lithium-ion batteries?

Yes, its low exotherm and good thermal conductivity make it ideal.

Can it be used with automatic dispensing equipment?

Yes, it has stable viscosity and good flow properties.

What is the dielectric strength after cure?

Typically >20 kV/mm.

Does it adhere to PCB substrates?

Adhesion is good to most substrates, but a primer may be needed for non-silicones.
