Product Details

Composition

It is madeofSaturated polyester resin, curing agent, pigment, filler and additives through melting, extruding, grinding and processing

Main features

● Ultra-durable performance;

● Good leveling property, excellent gloss for film; and

● Good physical mechanical performance, chemical resistance and heat resistance.

Application

It is applicable to coating on long-term exposedproducts

Product series

It can be made into many colors, such as products with aluminum powder color, bronze powder color, pearl powder color and other products with metal flash effect.

Technical indexes




Residue on sieve %125μm

0 or under discussion


Color and appearance of coating film

The coating film is complete with a little crocodile skin; the color meets requirements for color difference


Hardness

≥2 H


Gloss (60°)

Highlight ≥86, half light 21-85, non-light ≤20


Bending mm

2


Adhesive force (1×1 mm) Grade 6×6

0


Impact resistance kg.cm

≥50


Salt spray resistance 400 h

≤ Grade 1


Damp-heat resistance 500 h

≤ Grade 1


Thickness of film μ

50~60

Surface treatment

The corresponding treatment methods should be used according to different basis materials, such as phosphating, chromizing, shot blasting or sand blasting

1. After treatment of shot blasting or sand blasting, the surface should reach Grade Sa 2.5 and the surface roughness is 30 ~75 μm.

2. Phosphating: degreasing- derusting- neutralizing- surface control- phosphating- passivating

Appearance of phosphating film: The crystals on phosphating film should be compact, which shall be mixed continuously and uniformly.

3. Chromizing: degreasing- rinsing- immersion cleaning- deoxidating- rinsing- chromizing

Method of usage

It is applicable to high voltage static spraying and coating

Spraying and coating voltage: 50-90 kV; air pressure for spraying and coating: 0.1-0.2 Mpa; the distance between spray gun and work piece: 200-300 mm

Curing condition: 200℃/10-15 minutes, other curing conditions can be provided according to requirements of clients.

Repairing: The sand paper should be used for polishing missing points and coating the whole surface prior to the entire spraying, coating and curing.

Safety measures

The dusts should be avoided when using the powder coating regardless of the non-toxic features. Operators should wear suitable dedust masks and glasses. If possible, the skin should be avoided from touching powder coating for a long time and the coating on skin should be cleaned with soap.

Storage period

It should be stored in dry and well ventilated areas under 30℃ rather than exposed to direct sunshine; the service life lasts for 18 months and products should be inspected again if exceeding the period above. The products exceeding the period above can be still used as long as they meet the requirements.

Notes:

1. The surface under coating should be clean, and free from water, acid, alkali or oil;

2. All tools for construction should be dry and clean;

3. The powder coating should be used in one kind or one category and it is not allowed to be used by mixing with the coating of other categories;

4. The curing condition should meet regulations; otherwise, the film cannot meet requirements. The temperature for curing refers to practical temperature of work piece and the time refers to that for heat preservation after the work piece reaches regulated temperature; and

5. The construction site should be well ventilated and necessary protective articles should be needed.

Remarks

Please read Product Manualcarefully for correctly using the products.

Statement

The materials and data of products above are accumulated from our tests and experience, and can be used as guideline for construction. Since the service conditions of products are out of our control, we do not guarantee the information above. We have the right, from time to time, to modify the operating instructions with the constant improvement of the products.
