The temp range for this product is -62F to 350F, with excursions to 450F according to the manufacturer.

Is this silicone safe to wear against the skin in clothing? I want to use it inside a cap.

I would assume so because this is food grade.

Can this be in continuous direct contact with high temperature liquids that will be consumed by my family?

this is rated safe for intermittent food contact... and yes it is high temperature. so no, not continuous.

Does this attract dirt and dust once fully cured

It’s not tacky when dry so I don’t see it attracting more dust than any other surface
