Thermoplastic Coating Powder for Extinguisher Cylinder Inner Linings

PECOAT® Thermoplastic Coating Powder for Extinguisher Cylinder Inner Linings . Thermoplastic coating protects the extinguisher cylinder from corrosion and significantly extends the life of the cylinder. It can also protect the cylinder and extinguishing agent from chemical reactions with each other. This helps to providing longer and safer fire extinguishing time of usage. It also offer many advantages for applicators as well as end users, in temperate
and extreme environments.

We manufacture the internal thermoplastic coating powder for mild steel liquid-filled fire extinguisher. Thermoplastic powder coatings allow to build a relatively thick. Non-porous film with excellent corrosion and chemical resistance all in one step, which fulfils the most demanding properties i.e. foaming additives resistance & long-term protection.

Available Color: Gray

FEATURES

• Long term adhesion
• Foaming additives resistance
• Excellent corrosion resistance

HOW TO USE

Pre-treatment

Degrease – Alkaline/solvent degrease.
Cylinder should be Shot blasted or Iron phosphated.

Coating Parameters

• Pre-Heat Time : At 210°C-300°C for 90-120 seconds (depending on metal thickness)
• Dwell Time : 30 Seconds
• Post-Heat Time : 30 Seconds

There are two methods to use thermoplastic coating powder for extinguisher cylinder Inner linings

Roto/Spin Lining Coating

• In this method, the fire extinguisher is heated and then the powder is added inside the cylinder.
• The extinguisher is continuously tilted and turned.
• The powder melts and flows out uniformly inside the extinguisher.
• Once the article is coated, care should be taken to ensure it does not rub or come into contact with
  any surface, to prevent damage to the coating.
• At this stage, a rough powdery, but uniform coating on the article is obtained.
• The excess un-melted thermoplastic powder is shaken off with a slight jerky motion or light tapping.

Spray Lining Coating

• In this method, the fire extinguisher is heated up to optimum temperature.
• Now, the spray grade powder is sprayed inside the fire extinguisher with or without electrostatic
  charge.
• The powder melts and flows out uniformly inside the extinguisher.
• Once the article is coated, care should be taken to ensure it does not rub or come into contact with
  any surface, to prevent damage to the coating.
• At this stage, a thin and uniform coating on the article is obtained.
