Fusion Bonded Epoxy (FBE) Super Anticorrosion Powder Coatings for
Rebar
Introduction:
This series of products is one kind of thermoset pure epoxy powder
coating made of epoxy resins and epoxy hardener.
Feature:
---The film has high density and adhesion
---Excellent chemical corrosion resistance
---Excellent physical mechanical properties
---Curing reaction speed can be adjusted according to the customer
request to satisfy the requirement of different spraying
---Not suitable for outdoor use directly, without good
weatherability
Property:
Density: 1.2~1.8g/cm3(Owing to the different formula and different
colors)
Particle size: Different purposes varies, the standard for the
average particle size is 40 ~ 50um,
150μm powder on sieve ≤3%,250μm powder on sieve ≤0.2%
volatilization: ≤0.6%
Gel time: under 200℃≥12s, and in accordance with manufacturer’s
value ±20%
Thermal properties: ΔH≥45J/g,Tg2≥95℃
Storage stability: Pure Epoxy Powder Coatings should be stored
below 30°C in a dry and well ventilated place away from source of
heat and direct sunlight. If stored in an air-conditioner room, in
order to avoid damp again, before using the powder, the powder
should be kept at the room temperature or at the same temperature
with the spray equipment. Under such condition, the powder can be
stored stably for 12months.
Extended, retest will be required. If the testing result meets the
requirement, the powder can still be used.
Note: For the low temperature curing powder and powder with the
gloss below 40%(60°),the stored temperature should be below 30℃.
Film characteristics:
| Properties | Method | Value |
| Adhesion | GB/T 23257-2009 | ≤2 grade |
| Cathodic Disbonding | | (65℃,48h)≤8mm |
| Cathodic Disbonding | (65℃,30d)≤15mm |
| Anti-bending | (-20℃,2.5°)no crack |
| Coating thickness of test is 300-400μm |
Spraying: This series product is recommended to use high voltage
electrostatic spraying method to coat
Curing guide: 160-230℃/3-5min or customizing design according to customer’s
spraying condition
Field of application: Rebar,single, double and three layer FBE anticorrosion coating for
all kinds of steel pipeline of oil and gas
