QM-9025 Paint Drying Agent

Product Overview:

QM-9025 is a closed-type acid catalyst that can significantly reduce the crosslinking reaction temperature of paint in baking processes. Compared with unclosed catalysts, it has excellent storage stability.

Physicochemical Parameters:

Composition: Blocked acid salt

Appearance: Yellow transparent liquid

Effective content: 30%

Soluble: Isopropanol

Product Characteristics:

When used in solvent-based baking paint systems, it can significantly lower the crosslinking temperature of the paint. Within the recommended addition range, it will not adversely affect the paint film:

It can increase crosslinking density, increase the hardness and gloss of the paint film, and improve the corrosion resistance, hydrolysis resistance, solvent resistance, and mechanical properties of the paint film;

It can reduce production costs, improve the efficiency of coating production, and has good storage stability.

Application Systems:

Suitable for high-temperature baking paint, roll materials and tinplate coatings, etc. The unsealing temperature of this product is 90°C, and the recommended curing temperature is 100-225°C.

Recommended Dosage: 

The amount added varies depending on the system and baking temperature, generally ranging from 0.2% to 4% of the total (see table below). (Drying agent solids/resin solids):

Temperature (°C) – Dosage:
90 – 5.80
100 – 4.53
110 – 3.54
120 – 2.57
150 – 1.61
175 – 1.08
200 – 0.72
225 – 0.55
250 – 0.42

Packaging and Storage:

25kg/drum.

The product should be stored in a cool, ventilated place. Unopened, the shelf life is 24 months from the production date.
