THERMORA — PRODUCT SELECTION BRIEF
Cable fire-protective coating
Cable-coating enquiries for electrical infrastructure, trays and service tunnels.

Editorial selection guidance; dimensions in examples are enquiry examples, not confirmed supply specifications. Tested properties require grade-specific company documentation.

OVERVIEW
Cable fire-protection coating is specified around the actual cable route: jacket material, tray arrangement, installation access and the required fire-protection objective. It is a different material selection from a structural-steel coating. Coordinate coating compatibility and application requirements with the cable and project documentation.

SELECTION PARAMETERS
Product family: Fire-protective cable coating enquiries
Product form: Liquid coating concept in a sealed industrial pail
Illustrated finish: Off-white coated cable route; exact dry-film colour by grade
Substrate: Identify cable jacket material, cable types and bundle arrangement
Route details: Tray width, length, cable fill, access and service environment
Coating build-up: Wet and dry film requirements follow the documented product system
Application method: Confirm permitted brush, roller or spray procedure in the TDS
Compatibility: Check jacket adhesion, cable markings and electrical-service constraints
Quantity basis: Coated surface area and route geometry; not route length alone
Site coordination: Include isolation, access, curing and inspection requirements

REFERENCE ENQUIRY — NOT A SUPPLY SPECIFICATION
Example enquiry only: a 500 mm-wide tray route over 200 m, with cable layout photographs and required treatment extent. Coated area and consumption must be calculated from the actual arrangement.

GRADE-SPECIFIC EVIDENCE TO REQUEST
• Cable-specific test scope and treatment configuration
• Adhesion / compatibility, film thickness and coverage
• Drying conditions, handling data and storage life

Describe the cable system
Include cable jacket types, tray arrangement, fill and any existing treatment. Keep electrical performance requirements separate from coating-related fire behaviour.

Coordinate work on electrical services
The project team must plan access, service isolation where required, surface condition and compatibility checks. Follow the grade-specific instructions and local site procedures.

Separate coating from penetration seals
A coated cable route does not define the firestop at a compartment wall or floor. Schedule the coating and each penetration system as coordinated but distinct items.

FREQUENTLY ASKED QUESTIONS
Can structural-steel coating be used on cables?
Do not assume interchangeability. Cable coatings need documentation covering the relevant cable substrates, installation and intended performance.

Does cable coating provide a wall-penetration firestop?
Not by itself. Select a documented penetration system for the wall or floor opening and coordinate it with the cable route.

Can quantity be estimated from tray length alone?
Tray width, cable arrangement, treatment extent, required film and product consumption also matter. Provide layout information before calculating purchase quantities.
