Product Description

We no longer stock this product, but can recommend International Interchar 212 as a great alternative.

Sika Unitherm Platinum is an epoxy fire protection coating to be used on structural steel for interior and exterior conditions. It forms a heat insulation layer under the influence of fire and improves the fire resistance of steel parts like columns, girders and framework. Sika Unitherm Platinum is independently fire tested and approved to international test standards like EN 13381-8 and BS 476 part 20-22.

Sika Unitherm Platinum is for interior and exterior use on structural steelwork like columns, girders and framework with a highly effective protection to delay the steel temperature from reaching its critical temperatures for longer time. Particularly beneficial as a workshop material.
