Fused Ceramic 6 Puck to flywheel?

Joe@ZSpeed

The full face ceramic (not 6 puck ceramics) are more prone to fuse with a lot of slippping/abuse. If you throw enough heat at metal it will melt and can fuse.
True 6 puck style disk have a lot more open area to let the material cool, full face designs don't have as much area between the pucks for cooling so they will build more heat when slipping albeit they tend to drive slightly better for ceramics.

It can happen with any metallic type clutch material if it gets hot enough to melt the material.

You should never slip a clutch more than a second or 2. It is building a ton of heat during this time and wearing the clutch very quickly as well. Heat is the enemy of any clutch. Heat wears the material faster, It can also cause the diaphragm spring to lose tension/force if over heated enough times dropping the clamp load down.

If you do a hard launch with slicks etc and the clutch builds too much heat instantly and doesn't hold you can end up in the same boat as the clutch will slip under its full clamp force which really builds the heat quickly.

A properly rated clutch for your application should hold on a hard launch, It is best to side step a puck style clutch quickly rather than slipping it out of the hole (Caution, danger to drivetrain)

Slipping a clutch at high RPM out of the hole for a smooth launch is the worst thing you can do to a clutch. Yes drag cars slip their clutches out of the hole, They actually set them up to slip for the perfect launch but they use materials designed for this and rebuild them after every run!
