surfacing veil / for composites

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.
