The document describes an elastomeric coating system that provides superior protection for concrete and other materials. It combines physical and functional properties including high adhesion, flexibility, resistance to weathering and chemicals. The system uses a two-part primer and proprietary elastomeric top coat to stop corrosion and deterioration from acids, chemicals, weathering and other environmental threats. Independent lab tests show it outperforms epoxy coatings in elongation, adhesion, flexibility and durability.

4. Comparison to Epoxy
ROK Flex C
 Greater than 500% elongation compared to 5% for epoxy
 250% greater adhesion strength for superior bond
 Does not degrade with flex/stretch, freeze/thaw,
with solar cycling or UV exposure
Acrylic/Epoxy coatings
 Inherent brittleness
 Minimal elongation capacity
 Severe cracking during flex/stretch, freeze/thaw
and solar cycling
 Corrosive agents to penetrate epoxy cracks
resulting in corrosion, material degradation
and failure.
