Hilti CP 601S INSTALLATION

Installation instructions for CP 601s

1. Clean opening.

Opening

1. Clean the opening. Joint sides must be sound, dry and free from
dust, oil and grease.

Application of firestop

2. Insert fill of mineral wool (or backer as required).

3. Apply firestop over backer.

4. Smooth firestop sealant with a trowel before the skin forms.
Once cured, CP 601S can only be removed mechanically.

5. For maintenance reasons (not shown), a penetration seal could
be permanently marked with an identification plate. In such a
case mark the identification plate and fasten it in a visible
position next to the seal.

Chemical resistance

• At room temperature the cured silicone sealant is resistant for a
short time to diluted (≤5%) acids and lyes/alkalis as well as
commercially available cleaning agents and disinfectants (except
those containing iodine).

• Concentrated acids and lyes/alkalis destroy silicone rubber
over time.

• Solvents and mineral oils cause cured silicone to swell.
Consequently, proper functioning of the sealant should be
checked after exposure to a solvent / mineral oil.

2. Insert backing material.

3. Apply CP 601S. 4. Smooth CP 601S.

• Please contact your local sales representative or the nearest
Hilti center if special requirements for chemical resistance have
to be met.
