Water-based acrylic paint crystal

Water-based acrylic paint crystal series products use imported high-performance water-based acrylic resins as the main film-forming substance, supplemented with high-performance environmentally friendly pigments and additives, and use deionized water as the main dispersion medium, completely replacing traditional solvent-based coatings. Organic solvents such as benzenes and esters.

A detailed description

Product introduction

This crystal series product is a single-component baking varnish. It has excellent adhesion to the substrate and the appearance of the paint film after curing to form a film at a specific baking temperature. It has high hardness, excellent feel, good flexibility, high gloss, and fullness. Good wait.

The performance of this crystal series product has reached the American (AAMA-2603) standard. It can be widely used in aluminum products such as aluminum veneer and aluminum profiles, providing extremely excellent protection and decorative effects for the substrate.

Product Application Features

1. Convenience: no need to use hazardous chemicals and solvents, diluted directly with water when used;

2. Safety: high flash point, non-flammable, non-explosive, non-corrosive, and not a hazardous chemical;

3. Environmental protection: Direct emission of ultra-low VOC, solve the problem of environmental protection emission inspection, without using combustion emissions;

4. Energy saving and emission reduction: No irritating odor and soot are generated during the construction process, and the baking temperature of the paint film is reduced to 170-180 ° C to achieve the purpose of energy saving and emission reduction.

5. Easy spraying: suitable for a variety of water-based spraying equipment such as Japanese blue, French SAMES

Remark：

1、The above-mentioned process is aimed at the workpiece to be sprayed that has been processed, and the pre-treatment method of the workpiece can be made without special changes, which is the same as the original solvent-based coating.

2、During the construction process, to ensure a good construction environment, the production line should always be in a clean and dust-free state.

3、The water used for coating dilution is deionized water.

4、The low-temperature baking temperature should be appropriately adjusted according to the actual construction environment and equipment conditions of the spraying line. The recommended temperature setting range is 50-80 ° C.

5、After the paint film is cured at high temperature, the relevant performance test can be performed by leaving it at room temperature for 24 hours.

6、Before using this water-based product, make sure that the pipes of the spraying equipment are clean and free of impurities, oil, and other solvent residues that are incompatible with this product. Do not use strong solvents such as xylene, turpentine, and ethyl acetate to clean the pipes. Roads to avoid pollution and other irreversible effects.

7、Water-based coatings have extremely strong electrical conductivity during the construction process. Construction workers should ensure that electrostatic protection measures are taken to prevent electric shock.
