Finishmat is the Lantor range of surfacing veils for the composites
industry. Finishmat is used to improve surface quality in the broadest
sense of the word.
For instance:
- Improved cosmetics
- Greater chemical resistance
- Reduced abrasion of moulds
Each Finishmat product has its specific properties that make it
suitable for specific processes and applications.
Finishmat® D7760
The Finishing Touch!
 Finishmat D7760 is a needled
felt made of polyacrylonitrile fibres. D7760 is applied in RTM
processes, like vacuum infusion, RTM light and RTM. It prevents fibre
print through from glass fibres. For instance, It is used for truck
cabins, which are made with continuous filament mat in RTM, and are
painted afterwards.
Finishmat D7760 is a 60 grams mat of polyacrylonitrile. The standard
width is 1.10 m, but is available in other widths on request.
Key benefits of Finishmat D7760
- D7760 is applied right against the gelcoat in an infused laminate. It
reduces fibre print through and is often used in conjunction with Soric
TF applied against the skin coat. The most important benefit of D7760 is
that it reduces fibre print through of glass fibres in the surface.
This means a better surface quality. If painted, less treatment is
necessary. D7760 can be used in combination with a gel coat or as a top
layer without a gel coat.
- D7760 is chemical resistant.
- D7760 is heat resistant and can be applied in pre-forming processes.
- The refraction index of the PAN fibres in D7760 is the same as the
refraction of
polyester resin. This means that the fibres are not visible in the
resin.
Finishmat® 6691 range
The Right Protection
 Finishmat 6691 is a chemical
bond, polyester tissue. Finishmat 6691 veils are e.g. used in filament
winding and pultrusion processes. They create a smooth, resin rich
layer. This layer serves as a chemical barrier and creates a smooth
surface finish. The binder system used in 6691 is partially soluble in
styrene. This means that the material becomes softer when it is wetted.
This makes it easier to shape 6691 into curved products.
The Finishmat 6691 range consists of two weights:
- 6691 SL weighs 20 g/m2 (0.066 oz/ft2)
- 6691 LL weighs 40 g/m2 (0.13 oz/ft2)
The standard width of Finishmat is 1 m wide. Wider widths, up to 2 meter
(6.6 ft) are available on request. Lantor can slit 6691 into tapes if
necessary.
