Multifunctional coating dispersant LD-124
Multi-functional coating dispersant LD-124
(Similar to DEUCHEM 929)
First, Introduction
LD-124 solvent type coating dispersant (High Tech New Product of Jiangsu Province) produced with imported foreign advanced technology of Yangzhou Lida Resin Co., Ltd. has excellent performance and the quality is steady. It can totally replace the imported goods (similar to Hemmings 929).
Second, Main Physicochemical Properties
Appearance: Light yellow liquid
Density: 1.0-1.10
Viscosity: 200-350 Mpa.s
PH: 3-4
Effective content: 80-90%
Solubility: It can be dissolved in isopropanol、methylbenzene and mineral oil.
Third, Application performance
The product has the obvious performance in improving dispersity、anti-sink ability and storage stability in various kinds of pigment such as carbon black、phthalocyanine blue、titanium white、iron oxide red、medium chrome yellow. And it also has a good leveling effect, anti-sagging, saving the grind frequency and time, and improving the adhesive force and the appearance quality of the film. It can be used for general solvent type coating. Generally speaking, the main application performance is as follows:
1. Improving dispersity and anti-sinking ability for all kinds of organic pigments in organic phase.
2. Significantly reducing the system viscosity of inorganic substance in organic phase, adding the filling amount.
3. Increasing the color strength and reflectance of coatings obviously, improving cohesiveness of organic polymer to all kinds of metal, glass, concrete and inorganic materials.
4. Especially suitable for titanium dioxide, Improving the dispersity of titanium dioxide in polypropylene, hot melt terpene resin, epoxy resin, acrylic resin and alkyd resin.
Fourth, Application Scope
Nitro paint, alkyd paint, amino paint, chlorinated rubber paint, epoxy paint, acrylic paint, polyurethane paint.
Fifth, Usage and consumption (two usages)
1. Diluting the product with isopropanol or other solvent as per ratio 1:1, then grind in the pigment or filler. The recommended dosage is 1% of pigment or filler. The best used amount depends on test.
2. Adding 0.5%-1% of the total coating into paint vehicle, after mixing evenly then begin grinding and disperse by adding the pigment, filler.
Sixth, Points for Attention
This product has strong activity. You’d better add it in after sand milling to avoid reducing the product function, because it contains surfactant hydroxyl and carboxyl.
If adding excessive LD-124, it may lead to some defect of mobility aspect. And it may cause the possibility of extending the self-dry time for those coating which need to add drier, additional small amount of alcohol, ethylene glycol ether or other solvents and more adequate catalyst will make some compensation.
