| Coating | Advantages | Disadvantages |
|---|---|---|
| PVC | Easy to flame retard Weldable Totally water resistant Some chemical resistance High coating weights possible |
Poor solvent resistance (not drycleanable) Embittles on weathering Needs special additives for adhesion to synthetics |
| PU | Good chemical resistance Waterproof and drycleanable Bonds well to basecloths |
Subject to hyrolysis with age Difficult to flame retard Generally expensive |
| Acrylic | Excellent weathering Can be drycleanable Can be low cost |
Not easy to flame retard Needs special forulations to give good water resistance. |
| PVAc | Good adhesion Low cost |
Poor chemical resistance Poor water resistance |
| PTFE | Good stiffening power Heat and water resistant Excellent chemical and weather resistance Naturally fire retardand |
Expensive Difficult to weld |
| PE | Good adhesion Easy to heat weld Good chemical resistance |
Low melting point Relatively poor flex crack resistance Somewhat stiff UV stabilisers attacked by acid conditions |
