Kejian Receives High-temperature Vacuum Tape and Steel Structure Butyl Sealant Patent

SHANGHAI, Oct. 22, 2013 /PRNewswire/ -- Shanghai Kejian Chemical Co., Ltd. has received invention patent certificates for its high temperature vacuum bag sealing tape and steel structure butyl sealant from the Intellectual Property Office of the PRC.

The vacuum bag sealing tape was developed for the wind power, aerospace and yacht industries, etc. Based on advanced technology, the products have a high surface adhesion force on vacuum bags and a variety of tools.

This product has a wide temperature range and can be firmly adhered to the surface of a variety of tools used for autoclaving and oven curing. During the curing cycle it maintains its excellent seal and is very easy to remove from cold or heated surfaces once the curing has been completed.

1. Butyl sealant is a neutral sealant composed of single butyl rubber with excellent anti-aging/corrosion/oxidation, water resistance, and tightness properties. It also able to withstand deformations and cracking especially under low temperature circumstances and is a highly advanced sealing material.

2. Application:

Applies to all kinds of seams, holes and cracks in steel roofs. Butyl sealant has a perfect tolerance on structure strains resulting from tough weather such as strong winds, floods and storms, which often account for natural siphonage, i.e. leakage.

3. Features and Advantages

1). Butyl sealant is a permanent sealant with excellent elastic deformation along with steel plate expansion when hot and shrinking when cold, and will not result in sealant peeling off, thus outshining silicon sealant by offering unmatchable water resistance and tightness properties.

2). Butyl sealant is a neutral sealant without any corrosion for steel plates. It provides protection against cracks, seams and bridgings.

3). Butyl sealant has excellent anti-aging properties that last for 20 years.
