How can we coat inserts to protect a particular
part of the hand?
During the production of coated gloves, gloves
are immersed in a vat with the substance up to the level, to which we want to
obtain coating. However, first, the liner must be degreased and coated with
substances that allow the liner to bind with the coating. This allows to avoid
the coating disconnecting from the insert in whole sheets, which is often
found, for example, in cheap nitrile gloves.
What are
the types of glove coating?
- Coating only the fingertips – Provides the best breathability of the
globe. This coating is used in gloves intended for precision operations, e.g.
RS CONDUCTOR LEICHT.
- Palm coverage – provides protection to the inside of the hand, e.g. the RS
Ultra Tec glove.
- ¾ – a coating that also covers the fingers, but without the top of the
glove – allows the fingers to be submerged during work (e.g. the RS CITRIN
glove)
- Complete coating to obtain complete tightness of the glove and the
possibility of full immersion of the hand during work (e.g. the RS Opal 800, Topas
Voll glove).
In turn, what structures can we get by subjecting
gloves to further processing after coating?
- Smooth – without any additional treatment – the advantage of this
coating is tightness, but a worse grip especially in wet environments and lack
of breathability.
- ‘Crinkle’ – a sealed Surface, but wrinkled, which is achieved by the
action of corrosive substances. This coating gives us a better grip, but no
breathability. You need to pay attention to the diverse quality of these
products – they often have a large admixture of other substances and are in the
cheapest varieties.
- Sandblasted/sandy – the still warm glove is immersed in a substance that
etches the surface making it fluff to provide it with grip properties. The
advantages are breathability and a better grip. There are a lot of gloves and qualities
of these products.
- Foam – It has a sponge structure and a greater thickness – but a lower
density, it is less dense. Water passes through it much easily, but it provides
good insulation and is softer. It may brittle.
- Double coating – for the best sealing, some gloves are coated twice.
Tightness and porosity are obtained while combining the advantages and
disadvantages of both coatings.
