Product Details


Brief Introduction

1K water-based long-lasting antibacterial plastic coating is composed of high-quality water-based acrylic resin as the main film-forming material, long-lasting antibacterial material, supplemented by environmentally friendly pigments and water as a single component water-based plastic coating. The coating is long-lasting antibacterial properties, good adhesion, and good decorative effect. It can be widely applied on the surface of ABS, PS and other products for vehicles, toys, and household appliances, and provides long-lasting protective performance when matching used with long-lasting antibacterial varnish.

 

Component

Waterborne thermoplastic acrylic resin, long-lasting antibacterial materials, environmentally friendly pigments, water and additives.

 

Application

1. Toys and household appliances are decorated with plastic surfaces such as ABS, PS, and PC.

2. Electronic product coatings, etc.

3. Vehicle plastic coating water-based primer and top-coating.

 

Features

1. Broad spectrum sterilization: Quickly kill over 99% of Escherichia coli, Staphylococcus aureus, Streptococcus albicans, fungi, etc.

2. Long lasting effect: The antibacterial lifespan is synchronized with the coating lifespan.

3. This product is packaged as a single component and can be diluted with water-based solvents or water as a coating and cleaning tool. The operation is simple and convenient, and it meets with environmental protection requirements.

4. Matching used with long-lasting antibacterial UV varnish and long-lasting antibacterial PU varnish, the paint film is high hardness, good chemical resistance, and fullness after matching used.

Precautions

1. Before use, the paint solution must be thoroughly stirred and diluted with deionized solution to the operating viscosity, with a dilution rate of about 10-30%. Filter with a 200-300 mesh filter before operation.

2. The relative humidity of the operation environment shall not exceed 80% and good ventilation shall be maintained.

3. During operation, the surface of the coated material should be kept clean, dry, flat, and free of pollutants such as dust and oil.

4. Coatings should be stored in a cool and dry place, with a storage temperature above 0 ℃.

5. The storage period of the paint is six months, please be sure to exhaust it within six months.
