Description

3LPP (Standard ISO 21809-1:2018)

The epoxy powder coating is the implementation of ISO 21809-1:2018 standard, which

is the bottom design of the three-layer structure of polypropylene in buried steel-made pipe, using appropriate epoxy resin, curing agent, pigment, filler, etc., and can form a composite anti-corrosion system with excellent performance with intermediate layer adhesive and outer polypropylene.

1. Application scope and characteristics

●External anti-corrosion of steel pipe and pipe fittings.

●Compared with other forms of anti-corrosion, it has the characteristics of good adhesion, strong cathode disbondment, and collision and damage prevention.

●It has the characteristics of mature process, wide application range, long anti-corrosion life, and wide operating temperature range (-20℃ ~100℃).

2. Method and dosage

1 Coating method: Electrostatic spraying.

2 Theoretical dosage: 150g/M2/100μm.

3 Surface treatment: Sandblasting or Pelblasting.

4 Curing instructions: Apply the powder coating on the surface of 200~220℃. When the powder coating forms a gelatinized state, the middle adhesive layer is squeezed and wound, so that the two layers are integrated into one, and then wrap the polypropylene layer, and finally form a complete three-layer coating structure.
