Performance:
SL-4720 has primary OH groups for reaction with isocyanate, epoxy, silane or other condensation cured polymers and films. This provides durable properties to a cured system.
Due to the unique mono-functional silicone backbone and the difunctional reactivity of SL-4720, it is likely to be very effective at assembling and providing an effective molecular surface. SL-4720 contains no fluoroalkyl, so it is without the possible downsides of these materials.
Typical use levels for anti-graffiti properties are 1-5%. For slip properties alone, lower use levels can be used. In this case 0.1% is a good screening point.
