Product Information Sheet (PDS)

Thermal insulation resistant to temperatures up to 280 ⁰C

nC ProTherm CUI-HTF is designed and tested for temperatures between -180 ⁰C and 250 ⁰C with a peak up to 280 ⁰C (for 15 min)

Time savings with single layer application

nC ProTherm CUI-HTF can be applied in one layer, which saves a lot of time.

Direct bonding to metal

This saves time and money and makes for easy application. Already corroded metal should be pretreated with nC Corrosion Passivator, without pretreatment loose rust or paint should be removed.
