TEKNOPUR 360-800
Elastomeric coating
- 2-component
- 2-component
TEKNOPUR 360-800 is a two-pack, solvent-free elastomeric coating. Coating is applied by spraying. TEKNOPUR 360-800 is based on pure polyurea.
Used for special applications and for objects which are not exposed to chemicals and require longer geltime. TEKNOPUR 360-800 withstands impacts and abrasion. Coating yellows due to the impact of UV-light. When a surface with good colour retention is desired, the surface needs to be overcoated with TEKNODUR 0090 polyurethane top coat. The coating is usually applied to 2000 - 3000 µm total thickness

Surface preparation
Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods.
The place and time of the preparation are to be chosen so that the prepared surface will not get dirty or damp before the subsequent treatment.
More detailed instructions available in separate system descriptions.
Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.
Application
For two component application the components must be kept at a temperature of +20 - +25° C before use so that they are fluid enough for the feed pumps. To ensure that the product is uniform the base needs to be stirred thoroughly before use.
The ratio of the dosage pump must be 1 : 1. The heating shall be adjusted so that the temperature of the components is +75 - +80°C. The hoses are heated to the same temperature. Temperature of the mixture in the nozzle must be at least +70°C.
The film thickness is controlled from reference plate by dry film gauge. The maximum recommended amount to be applied in one application is 1500 µm. Thicker films are applied in phases so that the film is left to cool down between layers.
The mixing ratio is ensured by controlling the pressure on the feed pumps and consumption of the components and also by measuring the hardness of the coating (Shore A, ISO 868).
Directions given by the manufacturer of the twin-feed spray are to be followed when working.
Application conditions
The surface to be treated must be dry. During the application and drying period the temperature of the ambient air and the surface shall be above 0°C and the relative air humidity below 90%. The temperature of the surface to be treated must be at least +3°C above the dew point of the ambient air.
Storage
The storage stability is shown on the label. Store indoors in a cool and dry place and in a tightly closed can.
The hardener reacts with air humidity. Opened can is to be carefully closed after the use and it is recommended to be used within 3 days from opening. Barrels are to be equipped with desiccant tubes.
Product is applied by hot twin-feed spray, e.g. Graco Reactor or PMC PHX-2. The components are mixed in the pistol (e.g. Graco Fusion AP or PMC AP-2). The mixing chamber and nozzle are chosen according to the object to be painted. Recommended spraying pressure is 150-160 bar.
