Description

GreyStuff is an advanced, single-component duct sealing solution powered by innovative FyBrid technology. This neutral-curing, non-hazardous sealant is designed to withstand harsh environmental conditions, ensuring robust protection for cable ducts, bore holes, and other ducted networks. Its exceptional chemical resistance, water-tight, and gas-tight properties make it the top choice for industrial and commercial sealing applications.

Key Features of GreyStuff Duct Sealing System

  • FyBrid Technology: Enhances durability and performance for sealing cables, pipes, and ducts.

  • Non-Hazardous Composition: Environmentally friendly and safe for use in confined spaces and ex zones.

  • Single Component: Simplifies application with no mixing required, saving time and reducing installation complexity.

  • Intumescent Properties: Expands when exposed to heat, providing an additional layer of fire protection (only when used with DuctSeal FR).

  • Non-Adiabatic: Minimal Cable De-Rating: At 20mm thickness, the thermal resistance of 5.1 K/W allows efficient heat transfer, preventing excess heat buildup and ensuring the cable retains its full current-carrying capacity. This formulation supports optimal performance, even under high-demand conditions.

Benefits of GreyStuff for Duct and Cable Sealing

  • Water & Gas Tight Seal: Provides reliable protection in ducts and networks against water, gas, and fuel ingress.

  • Chemical Resistance: Resists hydrocarbons, methane, chlorine, and hydrogen sulphide, making it suitable for challenging industrial environments.

Installation

Cure Time
 Grey Stuff will cure 3-4mm daily, depending on the Humidity and temperature. The higher the humidity %, and temperature, the quicker Grey Stuff will cure. A minimum requirement of 20mm GreyStuff is required for an effective seal.

Cleaning
 Uncured material spillages can be cleaned with a solvent-based wipe.
Health & Safety
 GreyStuff is based on a neutral curing system that is hazardous-free  to protect users when carrying out tasks like sealing cable ducts.  Non-hazardous Zero MEKO.
Re-entry & Removal
 Grey Stuff will cure to a similar hardness of a rubber eraser, so re-entry and removal are achievable. The ease of this depends on the type of tools used. For example, a sharper tool will be easier than a blunt-ended tool. Only use sharp tools when cables are de-energised. AC Cable  Solutions accepts no responsibility for damaged cables.

Cable Suitability
 Grey Stuff is a single-component neutral curing system containing no solvents. Our formulation does not damage the properties of a cable  sheath or stain surfaces.
