1. Product classification

According to product color, spot colors can be prepared as required, and their type designations conform to the requirements of ZBA17005.

1. Technical requirements

The technical indexes of this product shall conform to the following requirements:

Item/Index:

Color / approximately the standard sample

Fineness (um) / ≤20

Tinting strength (%) / 90-110

Viscosity (coating No. 4 cup, seconds /25℃) / 50±30

Initial dryness (cm) / 30-50

Alkali resistance, water resistance / good

Storage stability (5-30℃) / good

Gloss (reflection gloss meter 60℃) / >40%

1. Test methods

5.1 Color is tested in accordance with the method specified in GB/T14624.1.

5.2 Tinting strength is tested in accordance with the method specified in GB/T14624.2.

5.3 Fineness is tested in accordance with the method specified in QB559.

5.4 Viscosity is tested in accordance with the method specified in GB/T1723.

5.5 Initial dryness is tested in accordance with the method specified in GB/T13217.5.
