Each year
millions of aerosol cans of WD40 are sold worldwide; whilst
WD40 is an excellent product with a long successful record,
we believe that we can offer a superior product to any person or organisation
wishing to break into this market.
As
most people will know, WD40 and other similar (generally inferior)
products are used in most households, workshops and garages, etc,
as a:
The
product offered by Vapor-Tek is sold under the tradename "Steelgard",
mainly to the industry for the protection of metal goods in storage,
transit or export. When packed in aerosol cans, it has shown itself
to be technically superior to WD40 in that it offers better
proven corrosion prevention.
The
product can be supplied in bulk in concentrated form to be blended
with White Spirit (Mineral Spirit) prior to aerosolisation. Blending
is a simple mixing operation that requires no specialised equipment.
Vapor-Tek
has no objection to the rebranding of this product under a distributor's
"own label".

- Mixing & Filling Data
Preparation
of Finished Steelgard
Steelgard GP concentrate is a viscous liquid at room temperature.
It can be easily pumped or poured. Moderate heating (30-35°C)
can help.
It is
mixed with "dearomatised" white spirit (mineral spirit)
of flashpoint approximately 40°C to yield the finished product.

| White

75% |

Note:
Suitable white spirit included Exxon's Exxol D40, Clairsol 310 (Carless)
and Finalan 40 (Fina). The concentrate is added to the white spirit
with agitation - a simple propeller mixer is quite suitable.
The concentrate can be poured or pumped into the agitated solvent
with agitation being continued for a few minutes after the addition,
or until a clear homogeneous solution is obtained.
Aerosol
Packing
Although Arcton (Freon) 12 propellant has been used in the past, hydrocarbons
are now preferred due to the phasing out of CFCs under the Montreal
Protocol. A suitable hydrocarbon is:
Butane:
80%
Propane: 20%
Specific Gravity: 0.56
Vapour pressure 40 psi (2.8 bar)
The proportions
are as follows:
Steelgard:
65% by weight
HC Propellant: 35%
The yields
for 200ml and 400ml cans are 8.5 cans per litre and 4.25 cans per
litre respectively.
