Description
ARMOUR - PRIME is a specialised, high adhesion primer
system designed to improve adhesion between polyurethane or
polyurea coatings and substrates. ARMOUR - PRIME is
particularly suitable when used in conjunction with Isothane
Polyurea coatings. It is a solvent free, zero VOC, two-pack
system. It acts as a sealer on porous substrates such as
concrete and will consolidate a friable substrate such as that of
asbestos cement. It acts as a barrier coat on bituminous
substrates and improves adhesion to difficult substrates such as
non-ferrous metals.

| Topcoat Application Time: |
The earliest overcoating time is when the primer system has dried but still has
a slight tack, eg; at 20°C this would be after ~ 2.5 hrs. The latest overcoating
time is 24 hrs after the primer application. After this it is necessary to re-apply
the primer. |
