AP-910 Sealant® : Water-repellent, High bonding strength Weathering, UV and Ozone resistant

  • AP-901 is a fire-resistant sealant based on a single component silicone compound.
  • In the event of fire or at temperatures in excess of 200℃ the sealant expands to about five to ten times its original volume. During this process a porous mass is formed, which has excellent thermal insulation properties. In contrast to conventional materials that swell under severe heat exposure, the expansion of AP-910 sealant is not caused by intumescence, but by a chemical process (Intumescence means then occurrence of volume enlargement under the effect of heat, caused by the surface structure being inflated by fumes origination from the product). The advantage of this is that the expansion of AP-910 of not accompanied by formation of large amounts of fumes.

Fire-Resistance Test : Accroding to FTP Code(2010) Resolution MSC.307(88)


FTP Code(2010) Resolution MSC.307(88) "A bulkhead which includes the cable transit should be constructed in accordance whit 2.1.1 of the recommendation and should be insulated to class A-60 on the stiffened side, which should be the face which is exposed to the heating conditions of the test" Systems tested with insulation at the exposed side have a limitation in the application. The bulkhead must then be totally insulated at both sides.
