Sika Unitherm Steel S - 60

Sika® Unitherm® Steel S-60 is a fast drying, thin film fire protection coating system for interior* and exterior structural steel work. Sika® Unitherm® Steel S-60 is forming a heat insulating layer under the influence of fire and improves the fire resistance of steel parts like columns, girders and framework.

USES
Sika® Unitherm® Steel S-60 may only be used by experienced professionals.

For exterior use on structural steel members like columns, girders and framework which are subjected to weathering, high humidity, maritime environment etc. with a highly effective protection to delay the steel from reaching critical temperatures.

* For interior use on structural steel members like columns, girders and framework as long as there is no demand for national emission schemes, i.e. German AgBB, etc.


CHARACTERISTICS / ADVANTAGES
  • Fast drying intumescent coating
  • Applicable on steel constructions exposed to weathering, the system meets Type X classification (i.e. exterior conditions)
  • Excellent corrosion protection properties according to ISO 12944, corrosivity class C3 (as coating system)
  • VOC < 320 g/l
  • Preserves the appearance of a steel construction
  • Applicable to filigree and complex steel building elements
  • Simple application, does not increase static load Individual coloration possible with corresponding topcoat, various colour shades in RAL, others available
