Primesol E is a thinner specifically intended for Primelack B and Primelack S steel primers, which are part of the PROTELACK SFP system.
Application
PROTELACK SFP system
Primesol E is an integral part of the PROTELACK SFP fire protection coating system.
The PROTELACK SFP system consists of:
- Primer coatings
PRIMELACK B, PRIMELACK S - Intumescent coatings
PROTELACK SFP, PROTELACK SFP FAST - Top coatings
PROTEFILM T
External applications
For outdoor use (category X), the Protelack SFP system must be protected with a polyurethane topcoat Protefilm T with a dry film thickness of 120 µm.
Internal applications
For internal conditions (category Z1), the system may be applied without a topcoat – the white fire-resistant paint provides an aesthetically suitable interior finish.

Characteristics
The PROTELACK SFP system consists of:
- anti-corrosion primer,
- intumescent fire protection coating,
- solvent-based topcoat.
System characteristics:
- High fire resistance (up to R120/R90).
- Suitable for both internal and external applications.
- High-quality finish, with topcoat colors available in the full RAL palette.
- Can be applied over steel elements already primed with other epoxy primers (no removal required), reducing project costs.
