​​​​​​​MasterSeal 735 AT

APP plastomeric bitumen torch-applied membrane with stabilized non-woven polyester felt reinforcement

MasterSeal 735 AT is a plastomeric modified bitumen waterproofing membrane (APP), industrially manufactured by impregnation of the reinforcement with the waterproofing compound-based on distilled bitumen modified with polyolefin polymers, which gives to the compound superior technical characteristics.

The composite reinforcement, made of nonwoven polyester in combination with fiberglass, conveys good mechanical characteristics, excellent dimensional stability and elastic performance. Shaping of sheets, straightness, dimensional and surface uniformity are accomplished by hot calendering of the mass at hot melt fluid state.

The upper surface is protected by a thin layer of talc. The lower surface is coated with a thermofusible polyolefin film.

Fields of Applications:

MasterSeal 735 AT is an excellent performance membrane. It is particularly suitable as top layer and as under layer in multi-layer waterproofing systems, with compatible membranes.

General roofing, vehicles parking roofs, foundations, on or under floors or ground slabs, wall constructions, are valid examples of the design application of this product. It is not suitable for roof gardens. It can be applied onto every substrate (concrete, masonry, steel, wood, insulation panel, membrane, etc.) and under heavy protection.

The excellent mechanical characteristics and high level thermo-dynamic stability make it suitable for any climate conditions and all the situations where a barrier against water is required.​
