| Description: |
High build, solvent free, two component, tar modified polyurethane with outstanding
physical properties in terms of flexural strength, tensile strength, impact, abrasion
and penetration resistance. A rapid cure, very short pot life version for use with
automatic/line travel spray equipment is also available (see Data Sheet A24).

Uses: |
Protection of steel and concrete structures in aggressive environments, i.e. internal
and external protection of pipelines, offshore splash zones, chemical plants, piling,
effluent tanks, etc.

when spraying if non-flammable material is necessary. Flash point: 208¡ãC (406¡ãF).
Under no circumstances must paint be thinned prior to application.
|
| Surface Preparation: |
| Steel: |
Ensure surfaces are clean, dry and free from contaminants. Grit blast to BS7079
Standard Sa 2.5 to an amplitude of 50-100 microns.
|
| Concrete: |
Remove all laitence and other contaminates by most appropriate method, i.e. blast
cleaning. Ensure concrete is dry to protimeter reading of less than 5 on the concrete
scale. Seal with U-Coat 501.
