 How
to use Etchweld
Aerosol:
Always shake the can vigorously for 2 minutes before
use. Non-aerosol product should be stirred thoroughly before
use and can be thinned up to 50% with cellulose thinners.
Weld
Through:
Ensure that the surfaces are clean and free of contaminants
such as corrosion, grease, oil, and paint. Where etchweld
is to remain uncoated in weld-through applications such as
face-to-face flanges two light coats applied at a distance
of around 25 cm are recommended at 7 - 10 minute intervals.
Before welding it is important to ensure that full flash-off
of solvents has occurred - at an ambient temperature of 20
degrees C 1 hour is sufficient, in cold conditions allow
up to 3 hours.
Etchweld can be MIG, TIG, ARC or gas welded.
To ensure instant and perfect welds when using spot welding
equipment clamp components together initially using clamping
equipment such as quick release welder's clamps, mole grips
or g-cramps etc. Ensure welder setting is adjusted by testing
on scrap steel of identical gauge as the work-piece. Mig
welders should be set to produce an even, constant arc,
spitting unstable arc is indicative of too high wire speed and
can be eliminated by adjustment. After assembly of hollow sections
seal seams with seam sealer or further paint coatings,
internal sections should be wax injected.

Etch Primer:
Adhesion promoter for:
Cellulose, synthetic, two-pack, water borne, water based,
stoving enamel, powder coat, alkyd etc.
Etchweld should be applied as a uniform coating at around 25cm
from the degreased, clean surface, and normally allowed to cure
for a period of 30 - 45 minutes before over coating, shorter
times are acceptable when using most top coats, however for thick
film coatings allow up to 1 hour before top coat application.
Etchweld will continue to chemically anchor to the substrate
under paint films for periods of up to 3 hours. As with any paint
system it is good practice to test paint systems at small scale
before use.
