BENTONITE RHEOLOGY MODIFIER HY-70W-2

Product introduction:

HY-70W-2 is a specially modified synthetic lithium magnesium silicate.The product expands by hydration solution, it will be forming a colorless, transparent and liquid glue solution.25% solution can remains liquid for a year.HY-70W-2 can rapidly form high thixotropic gel in the presence of a small amount of electrolytes, or when the formula contains resin and pigment wetting agents.

Application:

Products need to be pre-dispersed in water,Its dispersant can be added at any step.Including water-based coatings, industrial paints, household cleaning agents, ceramics and pesticide products.HY-70W-2 dispersions can be used to paper or other surfaces to form smooth, complete, conductive paint film.

 

Use Method

It is used to make 25% dispersion liquid. The process is as follows:

Adding the HY-70W-2 gradually under the condition of rapid mixing,and then continue to stir after 20 minutes, the viscosity of the system increases rapidly.stopping stir after it disperse evenly, and the dispersion aging for 1 hour, the viscosity will become lower than in the begining. Then stir it for evenly.The HY-70W-2 dispersing liquid does not require high shear force.

 

Package&Transport

HY-70W-2 should be stored in a dry place.and it must to avoid moisture absorption.

Generally, a 20%-25% dispersion of HY-70W-2 is used. The production process is as follows: Gradually add HY-70W-2 under rapid stirring conditions. Then continue stirring for 20 minutes. The viscosity of the system increases rapidly. After uniform dispersion, stop stirring and let the dispersion mature for 1 hour. At this stage, the viscosity begins to decrease. Then restart stirring to make it uniform. The production of the dispersion of HY-70W-2 does not require particularly high shear.
It needs to be pre-dispersed in water. The dispersion can be added at any step. It can form a highly thixotropic structure in various aqueous systems, including water-based coatings, industrial paints, household cleaning agents, ceramics, and pesticide products. The HY-70W-2 dispersion can be used for coating paper or other surfaces to form a smooth, complete, and conductive coating film.
HY-70W-2 should be stored in a dry environment to avoid moisture absorption.
