Product Description

 Product Introduction
PSA self-adhesive reactive cementation high polymer waterproof membrane (APF****0) is researched and developed by Keshun Company. It is the promotion project of Ministry of Construction (MOC), and the preferred product of national key projects and municipal works.
Keshun Company, striving for perfection and keeping innovating, cooperates with America Valéron™ Company to combine with special strong cross laminated film and Keshun’s pressure-sensitive self-adhesive cementation, which brings to a new level of APF and also the new self-adhesive waterproof membrane for waterproof area. Because of strong double superposition film and crisscross network design, the tear resistance, size stability, thermo stability and anti-ultraviolet will be greatly enhanced.
By patent construction method of moist substrate applied, the pressure-sensitive self-adhesive cementation of membrane reacts cross-linked chemically with cement glue, just like producing a strong waterproof layer on base course. This layer will never fails to bond with base course so that can make sure no water leaking and permanent of water barrier.

Precautions
The waterproof layer shall be protected by protective layer after acceptance check
The substrate should be clean and dry with method of applying substrate curing agent, and use patent finishing agent for substrate treatment.
Air of membrane must be exhausted with method of wet-application, and then roll it to make the pressure-sensitive self-adhesive cementation completely saturate with cement glue. Avoid stepping on the waterproof layer after constructed.
Transportation and storage
The storage environment should be dry and ventilated, avoid raining and shining before construction;
Preventing the inclined and horizontal pressure, the height is no more than 3 layers.
