ELASTOMERIC (MS) SEALANTS / PAINTS

Elastomeric simply means 'stretchy' or elastic in nature. The letters 'MS' stand for Modified Silicone polymers (ie paints or sealants).

Elastomeric or MS are any of various polymers having the elastic properties of natural rubber.

A material that at room temperature can be stretched repeatedly to at least twice its original length, and upon release of the stress, will return with force to its approximate original length.

The following table demonstrates the properties of Elastomeric or MS polymers compared to polyurethanes and silicones.


 

Examples of Elastomeric SEALANTS:


Henkel http://www.loctite.com.au/

The Loctite® brand, part of the Henkel portfolio since 1997, is renowned for the excellence of its adhesives and sealants. Since the original development of a unique anaerobic technology more than fifty years ago, Loctite® products have become vital components in many of the machines and products that are at the core of everyday life.

Bostik  http://www.bostik.co.nz/

At Zenith roofing we prefer to use Bostik Industrial Grade Silicone Sealant/Adhesive as it is a high performance premium quality neutral cure silicone sealant designed for sealing and adhering a wide variety of products and surfaces while also offering glazing and weather seal applications. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant.

Sika http://www.sika.co.nz/

We also use Sika Fosroc Silaflex MS because it was formulated specifically for sealing joints in and around concrete, brick, masonry, pre-cast panels, stone cladding, windows and doors.
