What is KBS Coating and Application of KBS Coating to Cables
Cables are in pioneer need of this technology world and if we think about the Fire Protection then cables are not exceptions from this.
KBS Coating
Coating is a water-based fire protective coating which is invented for offering the Fire Protection to group or bundled electrical cables as well as to Penetration Seals.
Moreover, the main function of KBS Coating is to stop flame circulation along vertical as well as horizontal cable ways. Additionally where circuit integrity depends on the distance of the cables from fire and the incurred temperature that time KBS Coating can delay short circuit.
KBS Coating shields electrical cables via ablation instead of insulation. Further, it is dense as well as thermally conductive in duration of normal cable operating temperatures. There are different ways for applying the KBS Coating so, take a look to these methods.
Surface Preparation:
In this cleaning of cables is not required but oil or grease should be removed with dry rags (no solvent). Use of broom or vacuum cleaner is advisable to remove heavy layers of dust.
Spray:
This Fire Protection is done in the conventional way by spraying crosswise. In such type of application white of the coating should well cover the color of the cable jacket and the wet thickness of the coating must be at least 2.5 mm on all exposed sides. Normally, the required thickness may be applied in one coat.
Brush:
Cable Coating through the brushing application requires numerous coats to build up the required thickness. Further, a thin coat applied first and then allowed to dry will aid in building up the required thickness.
Hand:
This Cable Coating tactic is adaptable in large diameter single cables or bundles; however, to achieve a smooth finish use of wet brush is advised. Moreover, thin coat should be allowed to dry before the rest is applied, using both hands like an extruder.
