Products for the construction Industry
Our
products for the construction industry our based around VPI (Vapour
Phased Inhibitor) technology. Please see the section 'Inhibitors
Explained' for more information.
Widely used in the concrete repair industry, 580 or MargelTM
(trade name) is a multi-part corrosion inhibitor providing a quick
release vapour inhibitor and other slower release compounds. These
provide a broad spectrum of protection, both short and long-term for
steel rebar's, with a life of up to 10-15 years depending on
installation conditions. In the construction industry this has been
used successfully on a large number of renovation projects, such as
bridge renovation, office blocks, multi-storey car parks, listed
buildings and residential (PRC) housing.
Typically
this is installed from the exterior of a building by drilling small
holes, inserting the capsules and sealing. Very importantly, this
negates the need for the existing surface to be removed, saving time,
money and avoiding many of the important environmental problems
associated with other systems. The installed corrosion inhibitor once
installed will migrate from the capsule through the concrete structure
as a vapour and chemically bond to the embedded steel providing
long-term and highly effective anti-corrosion benefits. It is important
to note that this will not reverse corrosion in steel, but will stop it
from further corrosion.
VPI 600 MargelTM (Patented Product)
A
Gel version of the above 580 product, which is supplied in cartridges
for inserting into smaller diameter holes or difficult to access areas.
The components work in exactly the same way as the VPI580, except they
are applied in a fluid form and once applied will form a solid over a
period of 12 hours. VPI600 is supplied in both 300ml and 600ml
cartridge sizes.
VPI 610 PU Injection Resin with MargelTM NEW PRODUCT FOR 2008 (Patent Pending)
VPI610
is a highly flexible, one component, solvent free, polyurethane
injection resin incorporating Margel corrosion inhibitor. Suitable for
water cut-off, void sealing and for cracks in concrete. The PU expands
upto 15x initial volume on contact with water, sealing voids and
cracks. The embedded Margel vpi will work over time to stop corrosion
of embedded steel.
VPI 901 - Solvent Free Metal Paint (New in 2008)
We
have introduced a surface paint on product for steel, that incorporates
our Margel corrosion inhibitor. Very importantly, the product is water
based and so is compliant with all current legislation regarding VOC
emissions. The product is suitable for painting directly onto steel,
the surface does not need to be rust fee. The product was designed by
QED over 10 years ago and was subjected to long term salt spray tests
against a major brand and standard red oxide and performed extremely
well. Please contact QED for more information.
