preparatory solutions used to create bonding conditions
Clean & Deoxidise Solution This
general-purpose solution is
suitable for the electro-cleaning of
most metals including FERROUS
and STAINLESS materials and
ALUMINIUM. It will remove
surface oxide films, light rust
and/or corrosion
specially developed electrolyte for
use on COPPER, BRASS AND
SIMILAR ALLOYS. This is
generally the only pre-treatment
required for these materials
Etch Activator D.C.F. Solution
When maximum adhesion is
required on IRON & STEELS
(excluding stainless steel) an
etching step must be used. The
presence of "flowed" metal
caused by surface machining or
grinding can cause poor adhesion
as the crystalline structure of the
Etch Activator D.C.N. Solution
When maximum adhesion is
required on ALUMINIUM and its
alloys an etching step must be
used. The presence of "flowed"
metal caused by surface
machining or grinding can cause
poor adhesion as the crystalline
structure of the surface is less
Activator SO1 Solution An

with Depassivating to activate/re-activate
chromium
Dalic Depassivating Solution
Used on certain metals such as
CHROMIUM, NICKEL AND
STAINLESS STEEL to remove
passive films not removed by
Cleaning & Deoxidising operation.
This solution is also useful when
plating onto two adjacent
dissimilar metals such as NICKEL
Should COPPER, BRASS or
SIMILAR ALLOYS require etching
then the most satisfactory
electrolyte to employ is
Etch/Activator No. 3. Its uses also
include the activation of Zinc and
Zinc based ALLOYS and also the
de smutting and activation of
When maximum adhesion is
required on STAINLESS STEEL,
ALLOYS with HIGH NICKEL
contents or high temperature
steels such as "WASPALLOY",
an etching step must be used.

This Cadmium
has been developed specifically for
the Aerospace industry and like
the Cadmium 1032/2022 system,
which it has superseded, can be
used to plate ultra high strength
steels without the need for post
plating embrittlement relief. The

Copper Alkaline A highly adhering
deposit normally used as a flash
coat before deposition of copper
acid. It can be deposited directly
on to steel and cast iron, with
good adhesion, but is not
intended for use a thick

compression areas
deposit, similar to
cadmium but relatively cheaper. It
is ideal for the repair of existing
zinc plate, zinc sprayed structurally
steelwork, and continuous zinc
coated wire and damage caused
by welding or fabrication. Unlike
hot dipped galvanising, Dalic Zinc
Tin is a soft metal widely used as
a non-toxic coating in the canning
industry, where tinned steel sheet
is produced by a molten dip
process.
Electroplated tin is more generally
employed to improve conductivity
and solderability, reduce
corrosion, prevent fretting attack
Nickel Epais HB A variation of the
standard Nickel Epais Solution
giving a more ductile deposit.
Suitable for uses where a change
from one solution to another for
build-up purposes is impractical.
Has the requirement of needing
high currents to achieve
satisfactory efficiency. This is the
work-horse of the Nickels.
Can be used with ease for the
reclamation of undersized parts.
Its efficiency factor is reasonably
consistent over the current
density range, even at low current
density rapid deposition is
possible. By using suitable
techniques deposits of 0.020"
DALINICKLE PLUS solution is
used to deposit non-fissured,
ductile nickel-plating with low
internal stress. It provides
excellent corrosion protection for
steel, even when applied in thin
coatings.
Thicknesses of around one
millimetre are quickly obtained.
cobalt has rarely been used in the
past because of the high cost of
bath plating. Dalic cobalt, with
properties similar to nickel, is
available and being used at
present as a wearing surface on
the slides of scientific equipment.
It has also been used on
alternative deposit to straight
nickel where additional resistance
is required and / or when the
component is subject to
temperature increase during
service. Thickness is virtually
unlimited
The brush electrolysis of the
ZINIDAL AERO solution is
particularly designed to protect
steel from corrosion. This binary
alloy is more suitable than
Cadmium or Zinc if a superficial
hardness is required or if the
treated part is to be occasionally
subjected to higher than normal
temperatures. In colouration it very

designed for plating a nickelcobalt
alloy. It is most often used
to bring parts up to dimension.

CADMIUM/ZINC PASSIVATING
SOLUTION
Suitable for producing an
iridescent chromate film on Dalic
electroplated zinc or cadmium.
PASSIVATION NO. 3 for ZINIDAL
AERO This solution has been
specially formulated to passivate
zinc-nickel electroplatings.
This treatment increases their
corrosion resistance thanks to the
growth of a layer of chromates in
surface.
CHROMIC ACID ANODISING
Selective area anodising is
particularly useful in cases where
the original anodic film has been
damaged during for example rework
or assembly. For the best
results the coating should be
sealed by treatment with boiling
water, however, where this is not
