APP/Sbs Modified Bitumen (asphalt) Self-Adhesive Waterproof Membrane

Description
SBS/APP is a modified bitumen base sheet consisting of polymer modified asphalt added viscosifier inside covering with different upper separated materials and underside with silicone antisticking layer. There have two kinds of thickness: 3.0 mm and 4.0 mm.

Where to use
Roofs or undergrounds.
Swimming pools, fire pools and reservoirs;
Subways or tunnels;
Open fires-forbidden construction areas;
Cold construction areas.

Advantages
Self adhesive, safe and environment-friendly;
Good tensile strength and elongation;
Strong adaptability for substrate shrinkage, deformation and cracks;
It will be a high-strength membrane to resist water;
Penetration-resisting and corrosion-resisting;
Excellent flexibility in low temperature;
Strong self healing ability for penetration and cracks.

Standards
GB 23441-2009

Storage
MBAAC material should be stored in well-ventilated place and avoid being exposed to the sun or rain. The temperature in stored places can not be higher than 45° C. It should be put vertically not more than in two levels.
 
Transportation
In order to prevent inclination or lateral drift, SAM-930A material can not be put vertically in double-level.
 
Application System
CANLON adhesive waterproof system includes substrate, primer, membrane waterproof underlayment, protection layer.
CANLON also provide a complete line of compatible accessories and components, including primers, pipe clamps, terminal battens and screws.
 
Surface Preparation
Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and uneven places need to be filled by polymer mortar.
 
Priming
Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.
 
Membrane laying
After substrate treating agent drying, lay MBAAC material according to application designs.
 
Sealing, fixing and constraining on vertical surfaces
On vertical surfaces, fix with metal battens and seal with sealants for membranes.
 
Application on protection layer
After membrane laying, apply on protection layer according to waterproof layer design.
