Company Description

Distribution of thermoplastic powder coatings and technologies. Thermoplastic powders base on PE, PP, PA for anticorosive protection of metal. 

Range of products / Services

Characteristic of POLISINT and THERMOFIX

Polisint and Thermofix are thermoplastic coating powder which has been specifically designed to provide a long lasting, tough coating for interior and exterior application to mild steel, galvanized steel and aluminium. It is based on an alloy of modified polyethylene.

 


Advantages

Excellent anticorrosion treatment of metal
Very good water resistance
Very good chemical resistance against acids, solvents and salts
Excellent mechanical properties – flexibility, impact and abrasion resistance, stress cracking resistance,
Very good touch feeling
Water and food contact approval
Electro insulation properties
Very good weather resistance
UV stabilization for external use
Excellent adhesion to the metal
Heavy metal free, halogen free
Higher thickness of coating - specific weight of polyethylene powder is that is more than 40 % lower then that of thermosets. That mean double size thickness can be reached with the same quantity of powder.

 

Processing of POLISINT

Polisint is applied by electrostatic (CORONA) spraying or electro kinetic (tribo) spraying.
Metal should be solvent degreased by phosphate system before application of powder. Aluminium should be chromate degreased to remove lubricants and processing soaps. For most purposes no further treatment is necessary. For better adhesion it is recommended sand blasting to Swedish Standard SA 2˝ to 3. Then powder is applied using a Corona Discharge gun or Turbocharged gun. After application the heating schedule should be 160°C to 220°C for 5-40 min depending on metal thickness. Thickness of coating ranges from 150 to 250 microns.

 

Processing of THERMOFIX

Thermofix powders are applied through the process of fluid bed. It is suggested to pre-heat the metal at a temperature within 250°C - 320°C, thicker thickness of the metal requires higher temperature of pre-heating. Suggested immersion time in bath is 3-5 seconds. It is suggested a heating after the application at 170°C-180°C to optimise the surface finishing. Thickness of coating ranges from 300 to 600 microns.

 

Application

Polisint is a new product on the market. It offers new possibility of polyethylene coating powder usage. Thanks to its above-mentioned characteristic and advantages it can be used mainly at:

Wire program
Fences, fencing columns and panels
Garden furniture
Battery boxes
Hand rails and holders
Pipes, fitting including potable water
Fan blades protection
Holders of any kind for exterior
Others
