Tikkurila Temadur 20 can be used as a single-coat paint for steel, zinc and aluminium surfaces with its anti-corrosion pigmentation, and also used as a primer or as a semi-matt topcoat in epoxy-polyurethane systems. It is also suitable for use on uPVC, please see the Tikkurila uPVC Refurbishment Case Study.

A two-component, semi-matt polyurethane paint containing anti-corrosive pigments, hardener aliphatic isocyanate.

Huge colour range available with RAL, BS & NCS shades

MED-Approved Product

Accepted for painting surfaces inside of ships with MED (Marine Equipment Directive) certificate no VTT-C-11979-15-17. MED approved products can be used for painting of interior furniture and other surfaces on board ships.

Materials used for interior decoration on board cruise ships must fulfil the fire safety requirements of the UN agency IMO (International Maritime Organization). If the ship sails under an EU flag, the product must be MED approved in accordance with the EU Marine Equipment Directive. At the same time, the quality system of the supplying company is regularly audited by an exterior quality system auditor.

For paint products, this means that the product has been flame spread tested, and the toxicity of its smoke and combustion gases has been assessed. The products that have passed the test have a low flame spread and do not emit toxic smoke or combustion gases.

Recommended Film Thicknesses and Theoretical Coverage

Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.

Drying Times

Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation.

Surface Preparation

Steel surfaces:

• Blast clean to grade Sa2½. (ISO 8501-1)
• If blast cleaning is not possible, phosphating is recommended for cold rolled steel to improve adhesion.

Zinc surfaces:

• Sweep blast clean with mineral abrasives, e.g. quartz sand, to an even roughness. (SaS, SFS 5873)
• If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with Panssaripesu detergent.
• For hot dip galvanized surfaces see separate application instructions or contact Tikkurila Technical Service or Rawlins Technical on 0113 2455450 (option 2) or send a message to [email protected]

Aluminium surfaces:

• Sweep blast clean with non-metallic abrasives to an even roughness. (SaS, SFS 5873)
• If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with Maalipesu detergent

Stainless steel:

• Roughen the surface by grinding or sweep blasting using non-metallic abrasives

Primed surfaces:

• Oil, grease, salt and dirt are removed from the surface by appropriate means
• Repair any damage to the primer coat
• Note the overcoating time of primer. (ISO 12944-4)

uPVC surfaces:

• Aged uPVC should be washed and cleaned, lightly abraded and 2 coats of Tikkurila Temadur 20 applied directly in the colour of choice

Recommended Primers

• Temacoat GPL-S Primer
• Temacoat GPL-S MIO
• Temacoat RM 40
• Temacoat SPA Primer
• Temacoat SPA 50
• Temabond ST 200
• Temabond ST 300
• Fontecoat EP 50

Recommended Topcoats

• Temathane 90
• Temadur 20
• Temadur 50
• Temadur 90
• Temadur Clear
• Temathane 50
• Temathane PC 50
• Temathane PC 80

Application Conditions

• All surfaces must be clean, dry and free from contamination
• The temperature of the ambient air, surface and paint should not fall below 5℃ during application and drying
• Relative humidity of the air should not exceed 80% during application and drying
• The surface temperature of steel should remain at least 3°C above the dew point
• Good ventilation and sufficient air movement is required in confined areas during application and drying

Mixing Components

• First stir base and hardener separately
• The correct proportions of base and hardener must be mixed thoroughly before use
• Use power mixer for mixing
• Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface and weaken the properties of the coating

Application

• For airless spraying, the product is thinned depending on the temperature of the components (base, hardener, thinner) and the required viscosity the paint approximately 0–20%
• Recommended nozzle tip is 0.011"–0.015" and pressure 120–160 bar
• Spray angle shall be chosen according to the shape of the object
• For conventional spraying, the product is thinned depending on the temperature of the components (base, hardener, thinner) and the required viscosity the paint approximately 0–20%
• Recommended nozzle tip is 1.6–1.8 mm and pressure 3–4 bar
• For brush application product should be thinned according to the circumstances

• Thinner 1048
• Thinner 1067
• Thinner 1061
• Thinner 1061 (fast) is also suitable for conventional spraying
