PMA 1200HD
Intumescent Waterborne Basecoat for structural steelwork. Indoors
Renitherm® PMA 1200 HD is a white thin-film waterborne intumescent coating
for the fire protection of internal structural steelwork.
For semi-exposed and exposed surfaces in combination with
Renitherm® TC Top Coat
Approval / Classification
Approved according to BS 476
Certified Certificate No. CF 5352
Environmental Benefits
Water-based 1C system
Free from halogens, APEO, borates,
plasticizers and silicones
Fire resistance rates from R15 up to
R180 for open and hollow profiles
Non-VOC acc. to ISO 11890-2,
LEED v4 confirmed
Application Area
• For indoor use only
• Structural steel profiles as columns / beams / girders / I - / H - sections
• R 15 – R 180 open steel profiles
• R 15 – R 180 hollow sections
• Up to R 180 usable without a top coat in dry indoor conditions** according to BS 476
• Coated steel components shall not receive coverings or miscellaneous jackets which prevents the in tumescent fire protection coating from foaming / expanding! Only those components may be connected force-fit, which complies with the same fire resistance rate
• The drying time depends on temperature and relative humidity
• At a temperature of approx. +20 °C and relative humidity of approx. 65% the drying time for layer ( up to 1,000 g/m² ) is at least 24 hours till the next application
• Each layer must be dried through ( fingernail test positive ) before the next application
• Lower temperatures, higher relative humidity, and insufficient air movement can prolong drying time
