Description
Two component polyurethane enamel, hardened by aliphatic polyisocyanate with high dry residueс.Scope and specifics of application
Polytex 3390 HS G95 enamel is used to create high-gloss (with gloss of ≥95%) finishing coatings with to high requirements for appearance.
They are used to paint commercial vehicles, special equipment, rolling stock (mainly for painting motive-power units and passenger compartments), large-sized vehicles, antenna-mast, support and modular structures, as well as other primed metal surfaces with high requirements for appearance.
The enamel coating has an even gloss, accelerated open time, excellent adhesion, excellent resistance to shocks, bends and other mechanical impacts.
Information on the material resistance to various media is available on request.
Main fields of application: mechanical engineering, power engineering, railway transport facilities.Instruction for use
Two component polyurethane enamel Polytex 3390 HS G95 is applied on primed surface. The surface can be abrasive blasted with grain Р-180 to Р-320.
Conditions
Basis temperature higher than dew point no less than 3°C.
Ambient temperature from +5°С to +30°C.
Relative air humidity no more 80%.
The process of applying
|
Blending |
Polyurethane enamel consists of two components: component А - basis, component B - hardener. Before use, pre-mix component A with a low-speed drill with mixing nozzle, then mix with component B in stoichiometric ratio in the delivery form. Mix the resulting material thoroughly until smooth. After the hardener is added into the semi-finished product, the material should be allowed to stand for at least 5-10 minutes. |
