ABABOL
RELEASE
Release agents bring to the surface of the mould
a special anti-adhesion characteristics and lubricity, being a barrier between the mould and the
piece manufactured, avoiding sticking and helping
the extraction.
For many years washes have been used directly
of diluted on some solvents, in majority of cases
with high toxicity. In the 70’s appeared the first semi-permanent release agents, based on polymers,
and then with a high concentration on solvents
(90-98 % of total)
In the 90’s appeared the first high performance
water based release agents. Those products were
widely used because of they were seemed as environmental and health friendly. Those products
have a high anti-sticking capacity and give the
surface a lubricity that helps the release process.
Some problems could appear when the mould had
to be painted with a gel coat or other kind of paint.
For those situations ABABOL has a range of products where the release capacity lubricity could be
under control.
With ABABOL PRODUCTS, they are free of solvents release agents, for gel coats, pieces that
need to be painted after demoulding or easy release keeping the same release capacity.
ABABOL DEMOULDS have 3 standard products,
based in an concentrated emulsion of high performance polymer on the field of antisticking, lubricity of plastic materials as polyester, epoxy, polyetilen, fenoplastics, vinyl and acrylic derivatives,
glass, metal, etc…. They have been formulated
with no organic solvents or alcohol, and no VOC’sbeing environmental friendly.
·ABABOL R recommended for use where the mould
must be painted with a Gel Coat, paint and high possibility of auto release.
·ABABOL R+ recommended for use where the
mould must be painted with a Gel Coat, paint and
some lubricity is needed to release the pieces.
·ABABOL G recommended for uses where a high
capacity of release is needed.
ABABOL DEMOULD, can also offer a range of specific release agents for other industries as rubber
and polyurethane, with a characteristics adapted
to that use. Also free of VOC’s and environmental
and healthy friendly.

Apply instructions
There are two main ways of applying release
agents: manually of with a spray gun.
SPRAY SYSTEM
MANUAL APPLY
It is important to follow the instructions for each
release agent application
1. Do not use cotton towels sponges and other absorbent materials because they could absorb important material.
2. Each piece of paper or towel you use to apply the
release agent must be discarded. You must avoid
mixing release agent polymerized with new ones.
3. Never use materials with pigments or other materials soluble on water because this can have an
influence in the polymerization of materials.
4. Adding more quantity of release agent other
than the recommendation does not improve the
release capacity.
We recommended a piece of cellulose paper. First of
all wet a clean paper with the release agent, and apply
uniformly on the surface of the mould, and then wipe
off. Due to the fact there is not solvent the wipe off
process does not have to be done immediately, except when the surface is hot.You can also use some
manual spray systems to apply the material.
The wipe off process helps a uniform distribution
of the material.
Standard cure time of release agents it is around
15-20 minutes at 25ºC. Some orientate data ( Fig.1)
After that time mould is ready for a new coat or
to start production.
Attached are links of some videos where you can
see manual applications of release agents.

When using a spray system there are some recommendations to follow:
1. The nozzle must be similar or lower than 0.3 mm
and air assistance. The volume of material must
be controlled.
2. The movement of the gun must be uniform
to guarantee a uniform proportion of sealer.
(Fig.2,3,4)
3. Hand speed must be adjusted with the volume of
release agent applied.
4. Every sealer has special regulations between
air and product. That regulation permits a perfect
spray. As orientate for 25ºC.
This is incorrect movement
This is the correct movement procedure.
Fig.1
Fig.2. The arm movement must follow the mould and not only the hand.
First picture OK.

Fig.4. In that picture you can see 3 kinds of marks consequence of:
excess of air, ideal use, excess of liquid.
Second picture incorrect
Fig.3. The movement must be left to right and not up and down.
In the last video, a product free of solvents and
water based, the spraying technique can be difficult, you must be sure of a perfect atomization,
and avoid excesses of release on the surface.
To do a correct spray is recommended 6:1 air/material relation and a low pass of product. The best
way is apply several coats with low volume. In that
case water evaporates immediately.
In the video you can see how keeping the gun
several minutes an accumulation of the sealer is
produced.
Mould temperature is also important. In a hot
mould polymerization occurs quickly. More material must be applied by step.
