Is this silicone reef safe?

[Kyuubi]

Found some silicone and I was wondering if it was considered reef safe? I need silicone to cover pvc piping with dry rock and sand for hidden cave work.
The silicone in question is called “FISTER 9-80 100% SILICONE SEALANT.”
Here’s some awful photos of the ingredient list haha, does any one know if this is safe to use?

Not sure. I've used this before. I'd go with anything that says "aquarium safe". I wouldn't risk it.
