4. xerofire®HP Fire Retardant Clear System

• xerofire® Isolator - a clear barrier-coat to prevent potential discolouration by acid-sensitive timbers.

• xerofire® Clear Topcoat - a clear acid-catalysed lacquer topcoat for use over xerofire® Basecoat.

xerofire® Isolator

A one-pack clear barrier-coat designed to isolate timber extractives. This is recommended to avoid potential discolouration, particularly with acid-sensitive timbers and fruitwoods such as maple, cherry and ash.

xerofire®HP Clear Fire Retardant Basecoat

A two-pack waterborne basecoat offering exceptional clarity and designed to retard the propagation and spread of fire to B-s1,d0 and National Class 0.

During a fire, the basecoat swells to form an insulating charcoal layer. This layer prevents oxygen and heat from reaching the substrate, preventing ignition:

1. Heat initiates degradation of the coating at around 250°C
2. The basecoat reacts to form char
3. The char expands
4. Expansion prevents heat from reaching substrate
5. Char eventually solidifies

xerofire®HP Clear Topcoat

A two-pack acid-catalyst furniture grade clear lacquer topcoat rated to FIRA 6250 Severe Use.
