SpecSeal® CS105 Cable Spray is a latex-based, ablative elastomer that intumesces to protect electrical cables against flame propagation. This water-based coating limits flame spread according to IEEE 383, IEEE 1202, IEC 60332-3, and Factory Mutual Class 3971 standards while providing exceptional coverage rates and easy application by spray or brush methods.

Key Features & Benefits

Water-based formula – easy installation and cleanup with no solvents or asbestos
Thixotropic properties – high-build application for superior coverage
74% solids content – highest coverage rates at 17.1 sq ft/gal at 3/32″ thickness
FM Approved Class 3971 – meets Factory Mutual requirements for grouped electrical cables
Flexible coating – forms water and weather-resistant protective film
No ampacity derating – maintains cable performance per FM testing
Dual protection – ablative and intumescent properties for comprehensive fire protection
Circuit integrity – provides short-term protection per IEC 60331-21
