1.Description
Kailai Self-adhesive polymer modified bituminous waterproof coiled material is composed of base material, including synthetic rubber like SBS, good heavy-duty road asphalt. The surface is coated by PE film, fine sand,aluminum foil film,and the silicon depositing release film or crepe paper is covered on the lower surface as anti-sticking layer.
-Classified by filler base: without filler(N),Polyester filler (PY)
-N lassified by upper surface isolation materials: Polyethylene film (PE), Polyester film (PET) and Double-sided self-adhered without film (D).
·PY Classified by upper surface isolation materials: Polyethylene film (PE),Fine sand (S) and Double-sided self-adhered without film (D).
·Classified by the physical and mechanical properties:Type Ⅰ and Type Ⅱ .
*Width :1000mm
*Length:10m,15m, 20m,30m.
*Thickness:-N:1.2mm,1.5mm,2.0mm
-PY:2.0mm,3.0mm,4.0mm
2.Feature
1)Excellent flexibility elongation,strong adaptability for substrate shrinkage, deformation and cracks;
2)Available for wet ground,low requirement for basic level,short construction period.
3)Lasting bonding and sealed performance;
4)Excellent adhesive properties, ,self adhesive joints with coil with life;
5)Strong self healing ability for penetration and cracks;
6)Excellent adhesive performance guarantees the integrity of waterproof layer,so as to prevent the occurrence of water channeling phenomenon
7)Safe application for low temperature,no pollution.

- Application Range
(1)(PE)Self-adhering polymer modified bituminous waterproof sheets is widely used for
* non exposed level, underground and indoor engineering;
*cut-and-cover metro,tunnel,pool,canal and etc.
*Especially in the waterproof engineering can not use open flame.
- The upper surface which is coated by aluminum foil film and fine sand is widely used for exposed waterproof engineering.
- Double-sided self-adhered sheet is widely used for pre-laid and assistant waterproof,
It can also compound with variety of materials to form multiple waterproof system.
