Ink dispersant HH2016D

• HH 餐厅-2016D Solvent-based dispersant

It is a wetting and dispersing aid for solvent-based coatings, used to disperse organic pigments, inorganic pigments and carbon black in organic solvent media. It can improve pigment wettability, reduce the time required for the grinding process and stabilize pigment dispersions.

It deflocculates the pigment through the steric hindrance of the polyacrylate chain and prevents pigment flocculation and precipitation during storage. Since the deflocculated pigment particles are very small, high gloss and enhanced color strength can be obtained.

另外, transparency and hiding power are increased. These products can reduce the viscosity of the system, thereby improving the leveling of the product and increasing the pigment content.

• 应用

特点和优势

1、Improves the wettability of the pigment, reduces the time required for the grinding process, improves the gloss and leveling, reduces the viscosity and avoids thixotropy.

2、Prevents the re-flocculation of the pigment through the steric stabilization of the polyacrylate chain in the block polymer, so that the tinting power and hue of the pigment in the coating and pigment paste can be stabilized, preventing the flocculation and precipitation of the pigment during storage, and keeping the pigments and fillers in the system evenly dispersed.

3、Since the dispersant has a high molecular weight and similar properties to the resin, it will not affect the durability of the coating base material.

• 推荐用途

Used in industrial printing coatings, architectural coatings, coil coatings, 汽车涂料, wood and furniture coatings, anti-corrosion coatings, pigment concentrates and other systems.

添加量

Recommended Levels:

Organic pigments: 10~20

二氧化钛: 2-5

Carbon black: 20~30

Inorganic pigments: 2-10

*.Please do a step experiment for the specific amount of addition, the above dosage depends largely on the particle size and specific surface area of the pigment.

Instructions for use

实现最佳性能, 应先将添加剂添加到研磨中, 其次是颜料. 预混合研磨的树脂和溶剂成分, 然后在搅拌的同时慢慢加入添加剂. 在添加剂充分混合之前不要添加颜料.
