ISOSEAL ® P 0713, P 2729

ISOSEAL ® P consists of a polyester-fabric impregnated with a thermosetting epoxy-resin which remains flexible after curing.  ISOSEAL ® P 0713 and ISOSEAL ® P 2729 have a different B-stage grade.   ISOSEAL ® P 2729 shows lower resin flow.  The standard type is ISOSEAL ® P 0713.  The resin in ISOSEAL ® P is softening under temperature and gives a tight and smooth waterproof surface after curing.  ISOSEAL ® P remains flexible after curing and can be formed without damage to the insulation.  ISOSEAL ® P has very good tension and elongation properties and are therefore taping without wrinkles is possible.
