DSC — Double Siliconized Cloth
DSC (Double Siliconized Cloth) is APCO's double siliconized canopy fabric. Per the manufacturer it sits at the top front — the most porosity-critical area, where most of the lift is generated — and is covered by the 3-year/250-hour warranty.
Also known as: DSC · Double Siliconized
What the manufacturer says
APCO describes DSC on its product pages with two statements:
“double siliconized cloth — top front is critical area in terms of porosity as this is where most of the lift is generated”
“double siliconized cloth for maximum durability”
The double siliconized cloth thus sits at the top front of the canopy — where porosity loss costs the most lift.
Warranty
APCO covers the fabric explicitly: “Double coated siliconised cloth (covered by 3 years / 250 hours warranty)”.
Where it is used
DSC appears on the product pages of current models including the F3 MKII, F7, NRG III, Game MKIII and Karisma II Paramotor. The exact cloth combination of a model is in its datasheet under “Sail Cloth”.
