QM-3704 Substrate Wetting Agent

Product Overview:

QM-3704 is the most common acetylenic diol wetting agent, possessing strong dynamic wetting ability and widely used in the printing industry, exhibiting good anti-foaming effects. Acetylene diol wetting agents have extremely low dynamic surface tension, while silicone-based wetting agents have very low static surface tension; typically, combining the two yields excellent results. QM-3704 also functions as a pigment wetting agent; when used in combination with dispersants, it can accelerate grinding speed, promote color development and stability of pigments, and also provide a certain degree of anti-foaming effect.

Physicochemical Parameters:

Composition: Alkynesidiols

Appearance: Pale yellow liquid

Active component: 50%

Solvent: DPM

Product Characteristics:

Reduces the dynamic and static surface tension of the system:

Issesses defoaming and foam-suppressing effects due to unstable foaming;

Adjusts the hydrophilic-oleophilic balance of the system, improving the color development and storage stability of the coating, and preventing color floating and blooming;

Low water sensitivity, with excellent substrate wetting and pigment wetting effects.

Application Systems:

As a substrate wetting agent, it is suitable for various water-based coatings and water-soluble coatings;

As a pigment wetting agent, it is suitable for the preparation of various water-based color pastes, added before grinding.

Recommended Dosage:

As a substrate wetting agent, its addition amount varies depending on the requirements, generally ranging from 0.1% to 1% of the total formulation;

As a pigment wetting agent, the addition amount is generally 0.1% to 0.4% (of the total formulation) or 30% of the effective amount of the dispersant.

Packaging and Storage:

25kg/drum or 200kg/drum.

The product should be stored in a cool, ventilated place. Unopened, the shelf life is 12 months from the date of production.
