About the product
HENSOTHERM 421 KS is a water-borne intumescent coating for indoor use, which reacts under the influence of heat by swelling to many times of its orginal thickness and producing a layer of carbonaceous foam
that acts as an insulating layer to delay the steel from reaching its critical temperature.
Possible fire resistance rates are R15 - R150 for open steel profiles and R15 - R180 for closed steel profiles. Approved according to EN 13501-2, ETA No 16/0251, with CE markings applied according to 93/68/EWG.
Remove from the surfaces any contaminants that might be detrimental to surface preparation and painting. Remove also water-soluble salts by using appropriate methods. HENSOTHERM 421 KS is designed to be applied over suitable prepared and primed steel substrate. Steel preparation by blast-cleaning to grade Sa 2½ (ISO 8501-1). Suitable primers are epoxy primers TEKNOPOX PRIMER 4, TEKNOPLAST PRIMER 5, TEKNOPLAST PRIMER 7, INERTA PRIMER 5, water-borne epoxy primer TEKNOPOX AQUA PRIMER 3, alkyd primer TEKNOLAC PRIMER 0168-00 and water-borne acrylic primer KORRO AQUA 2741.
