better performance than BYK-163 dispersing agent LD-1650

Descripción del producto

First, Product Description
 
LD***3 is kind of polymer type super dispersant which contains multi-alloy group. It is applied in all kinds of system and has great wetting and dispersion to all kinds of organic pigments especially carbon black. It is excellent for viscosity reduction, steady and hue strength improving. Also it can lower operation viscosity of grinding system and increase pigment filler amount. At the meantime, It has strong ability of prevent flocculation from returning thick. Whats more, it can improve storage stability of color paste, this product is similar to BYK***3.
 
Second, Physical and Chemical Parameters 
 
Composition: High polymer typepolyurethane Block Copolymers which containspro pigment group
Appearance: Light yellow liquid
Activity content: *0%
Solvent: Mixed solvent ofpropylene glycol monomethyl ether acetate and butyl acetate
 
Third, Features
 
 

1. LD***3 is suitable for middle and high polarity system. It matches well with common coating resin and applied well in coating system.
2. LD***3 can improve base materials wetting and dispersion ability to pigment/filler. Meanwhile, lower system viscosity, enhance fluidity and shorten grind and dispersion time.
3. LD***3 possesses excellent ability of prevent seeding. Compared with small molecular type wetting dispersant, it can improve colorants storage stability.

1. Adding the product into the base material and mixing well, then add pigment/filler for dispersion. It is suitable for any dispersion method such as sand milling, roll mill and ball milling.
2. Consumption is 0.**2.0% of formulation amount. If applied in colorant, the consumption is 3%.
3. High pigment carbon black, acetylene black and high grade organic coatings need pre-immersion treatment. We can firstly make LD***3 dissolved treatment liquor, then add pigment and mix at high speed for ****0 minutes. After *2 hours placement, grinding it to required fineness, the effect will be great.
