YRFC-11 is faintly acid dispersant which has excellent powder dispersion and viscosity reduction effect. It is recommended to be used for single component silicon PU materials with high powder content, runway materials, etc., without affecting the curing speed of materials.
Product Name: High efficiency Dispersant YRFC-11
(Viscosity Reducer / Leveling Agent / Anti-settling Agent)
Property:
Brown transparent liquid with slight odor, slightly soluble in water, soluble in general polyurethane system. Typical physical property data are as follows:
Density g/cm3 (25℃)： 0.936
Chroma(Fe-Co)： ≤10
Viscosity mPa.s (25℃)： 850±200
Function and Application:
YRFC-11 is an efficient anti settling dispersant designed for solvent-free runways and silicon PU materials. The characteristic groups contained in its structure can be dispersed and adsorbed on the surface of a large number of powder particles by adding a very small amount, which effectively reducs the adsorption between powder particles, so as to reduce the viscosity of the system, improve the leveling property, reduce scratches, and prevent the accumulation and hardening of powder fillers. The application characteristics of the product are as follows:
The effect of viscosity reduction is immediate. The experiment shows that for the medium viscosity system (the viscosity is about 10000mPa.s), the viscosity can be reduced by 70% if only 0.1-0.3% of the system powder is added; For some very high viscosity systems (the viscosity is about several hundred thousand centipoises), the viscosity can even be reduced to 1/10 - 1/20 of the blank.
Prevent settlement and hardening. Even if cheap large particles (400 meshes) are used, they will not agglomerate and harden at the bottom of the barrel after long-term storage, and will disperse with a little stirring.
Effectively reduce surface defects such as bubbling, bulging and depression.Significantly reduce the viscosity, improve the material fluidity, greatly improve the leveling during construction, reduce scratches, improve the wetness and filling of small holes on concave and convex substrates (such as cement foundation), and facilitate the timely discharge of air in the holes to reduce bubbles.
Reduce costs. Benefit from the excellent viscosity reduction effect, the amount of filler can be increased to a certain extent to reduce the overall cost.
User's Guide:
Add it into the filler components while stirring, and cut them properly for even dispersion without special temperature control. The recommended dosage is 0.1-0.3% of the powder.
Handling & Storage:
Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain. And pay attention to airtight storage.
Package: 25kg/200kg in HDPE drum
Shelf Life:
The unopened shelf life is 24 months from the date of manufacture. After the shelf life, if the dispersion and anti sedimentation are not reduced, it can still be used as qualified products.
