Multifunctional anti flash rust agent LD-900A

First, Product introduction

Ld-900a is a new metal chelate anti-corrosion and anti flash rust agent, which mainly solves the flash rust problem of water-based coating in submerged arc welding substrate.

It is mainly used to solve the problem of flash rust in the early stage after the application of waterborne metal coatings. It can not only effectively achieve the purpose of oxygen isolation, but also produce effective corrosion inhibition effect, which helps to improve the long-term corrosion resistance and salt spray resistance of the coating. For different metal substrates, such as carbon steel, stainless steel, copper alloy, aluminum alloy and other materials have good corrosion inhibition performance. It does not contain nitrite and chromate to reduce the pitting corrosion of metal materials.

Second, Product features

1. Excellent flash rust resistance of submerged arc welding.

2. Under high humidity, the construction of base material with rust and oil helps to improve the corrosion inhibition ability of substrate, and improve the long-term corrosion resistance and salt spray resistance of the coating. The salt spray resistance is increased by 24-50 hours with 1% addition.

3. Excellent wetting and dispersibility of pigment. Adding in the grinding stage can reduce the amount of dispersant, and the wetting agent can not be added. After grinding, the color development, plumpness and brilliance of the slurry can be improved to a higher level.

4. The appearance effect of the film can be improved after adding, and the gloss can be increased by 2-5 ° in general

5. Suitable for water-based system with pH ≥ 6

6. When making water-based zinc rich paint, 10-30% of zinc powder added in D-90 can be used as one component zinc rich paint.

Third, technical data

Appearance: light yellow liquid

PH value: 7.0-9.5

Specific gravity (20 ℃) g / cm3: 1.0-1.1

Fourth,Product usage

Waterborne alkyd coatings, waterborne acrylic coatings, waterborne epoxy coatings, waterborne polyurethane coatings, other waterborne industrial coatings, etc

Generally, the dosage is 0.5% - 2% wt of the whole formula, which can be added at any stage. The epoxy two-component system needs to be added to the curing agent component. When the humidity is high and the temperature is low, the addition amount is increased. D-90 is weakly alkaline. Pay attention to labor protection during production and operation. Avoid contact with skin and eyes. Rinse with plenty of water after contact.

Firth,Packaging and storage

25kg / 50kg plastic barrel.

It is suggested that the product should be stored in a cool place at room temperature at about 5-35 ° C. the shelf life of the product is 24 months from the date of production if it is not opened.
