Vector
protection
Vectors transmit germs from e.g.
mosquitoes, ticks, lice etc.
• Anti-mosquito protection
One-side instable foam coating with
TUBICOAT MOP + BEMATIN PER 40
(optionally including Comfort Control
Finish!)
Application on articles made of cotton
or cotton blends.

Wearer comfort
• Comfort Control Coating
One-side application of fluorocarbons to
obtain the bi-functional properties of
clothing articles.
The outside of the fabric becomes
water-repellent by the hydrophobic
coating. The inside of the fabric,
maintains its hydrophilic character and
makes humidity be fast absorbed.
