Micon Intusayf

Dry film thicknesses to achieve a one hour fire rating on steel sections have been calculated by the CSIR and are easily obtainable through computer software. It is essential that a Micon, or similar, base coat is applied to the steel section prior to the application of Intusayf and finished with a protective Micon top coat. For protection of PVC armoured cables a base coat must first be applied followed by two coats of Intusayf to achieve a DFT (dry film thickness) of 250 micron. It is recommended that a protective Micon top coat is then applied.

Micon offer a range of intumescent coatings for fire protection of structural steel and other substrates. Intusayf provides fire resistance to structural steelworks when applied in accordance with predetermined dry film thicknesses. Intusayf can also be applied to combustible materials such as electrical cables, PVC pipes and wood to enhance fire resistance by limiting spread of flame.

Micon Intusayf products are non toxic and environmentally acceptable.

At temperatures in excess of 200 degree Celsius, Micon Intusayf first softens and then expands up to 20 times its applied thickness to form an insulated foamed carbonised char that reduces the rate of temperature increase in steel and hence prolongs its load bearing capability. Toxic gas emissions are neglible, water resistance good and char stability excellent. There were no signs of cracking or loss of adhesion when applied to a PVC armoured cable

Micon Intusayf can be applied either by brush, roller or airless spray to most surfaces free from dusty, oil, grease and other contaminates.
