3mm/4mm APP Modified Bitumen Roofing Waterproofing Sheet Membrane

What combines APP? (Atactic Polypropylene)

--- Base materials:  polyester felt, or glass fiber

--- dipped and coated with:  APP, or APAO plastomer modified bitumen

--- Both sides covered with:  fine sand, mineral granular, PE film, aluminum foil.

APP Advantage?

A thermoplastic polymer, which forms a uniform matrix within the asphalt. This enhances the bitumen's performance by increasing its UV resistance, increasing its flexibility at low temperatures, and improving its flow resistance at high temperatures. APP modified bitumen sheets are generally applied using a propane-fueled torch. Applicators use the heat to soften the modified bitumen on the underside of the sheet. The sheet's bottom surface becomes a molten adhesive, which flows upon the substrate and then cools to form a waterproof adhesive bond. Some APP sheets can also be applied with cold-process adhesives

Models and Performance Index

Attention:

Make sure the roof deck smooth,clean,and dry (moisture<9%),then apply the surface of roof deck homogeneously with a kind bitumen paint,till dry to start application.

1) Heating and melting method

Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted(not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.

2) Cold adhesive method

Pour the cold adhesive homogeneously on the roof deck, then roll the membrane to install it to be fully sealed to roof deck.

By heating and melting method and by cold adhesive can be used in alternation in application as requested. After application, a full serious inspection is required to sure no air bubble, no fold, no falling away. ect.

Storage and Transportation:

1) Separate storage for different models.

2) Temperature should be below 50 ℃.

3) Avoid direct sunshine, rain, keep ventilated.

4) Do not piled horizontally, keep stand and not more than 2 floors.
