                 Guar ether : Superior Water-retention agent
                               Thickener & Rheology-modifier
                                     Guar Gum is a polysaccharide extracted from the
                                     seeds of the guar beans, grown in Southern Asia
                                     for centuries. Jingkun has been souring the unique
                                     material from this region for 20 years, controlling
                                     each stage of the extraction and processing to
                                     assure consistent quality.
                                     The exceptional properties of this biocompatible and
                                     renewable plant are the basis for Jingkun’s guar
                                     ether products for construction industry.
What is HPG?
Guar gum is extracted from the seed of the leguminous
shrub of Cyamposis tetragonoloba. Leguminous is
cultivated in the semiarid region of tropical countries
particular in India/ Pakistan. It is usually found in the form
of "splits", that are the endosperms of the seed derived from
the husk and from the inner proteinic part. Guar gum in the form
of powder of different particle size, which is obtained from
the splits by milling.

Hydroxypropyl guar gum (HPG) is synthesized by the
etherification reaction with nonionic propylene oxide
reagent with guar gum. This modification can significantly
improve the important properties of unmodified gum like
alkaline stability, hydrophobicity, solubility, biostability etc.
in context to their application in construction application.

The adequate degree of molar substitution in HPG lead to excellent water retention properties,
which is most important parameter in most of the construction application. The HPG improve
the performance / workability when typically applied in tile adhesives, tile grouts, cement based
wall putty, cement / gypsum based plaster, cement based texture plaster, cement / gypsum
based crack filler, flooring and leveling compound etc.
Due to its excellent thickening efficiency and pseudo plastic rheology behavior, this product
also helps to improve the sag resistance of plaster/ mortar when apply on vertical wall.
Characteristics of HPG


Water retention
Water retention in most of the building materials is one of the most important parameters.
It gives the capability of the mixture to maintain water inside, by allowing a better setting of the
binder and reducing the unpleasant effects of the plastic shrinking.

As per the picture showed, we made two sets of mortar.
One containing HPG JK-705, and one without.
Place same weighted quantity of two mortar separately
on a filter paper.
The filter paper absorbs the water from the mortar
without JK-705; while the mortar containing JK-705
remains the water inside for a long time.
In this case, JK-705 shows good water retention ability
when it applied in the mortar.

Characteristics of HPG


Consistency
Consistency is an important parameter to avoid the plaster sagging and improve the resistance
to the tile sagging when applied on the vertical wall.

As per the picture showed, we made two sets of mortar.
One containing HPG JK-705, and one without.
The mortar contains the JK-705 gives good standing
and still strength on spatula while another mortar
straight runs out from the spatula.

Characteristics of HPG


Rheology modifying

The water contain in the mortar acts as lubricants for the solid particles when mortar is spread
on the surface of the objects to which it is applied. The proper amount of water gives mortar the
“ pastiness” or “ creaminess” which is suitable for uniform and easy application.

This rheological characteristic of the final mortar mixture are very important and it depends on
the kind and amount of different ingredients used in the mortar.
The simple mixture of cement, sand and water is not suitable for use as a good mortar because
of the lack of the above rheological characteristics and also because of its poor processing.

This problem can be overcome by selecting the additives used in the formulation of mortars
which act as a both water retention aid and rheology modifier.

This additive is HPG, which exhibits the specific characteristic of bonding and coordinating a
large amount of water once they are dissolved in water.
Why Choose HPG?


  ●   Compared with cellulose ether, HPG is easier to soluble in water.

  ● Due to similar water retention ability, HPG can replace cellulose ether with
  x equal quantity for application of low viscosity & small dosage.

  ● For application of high viscosity & big dosage, HPG can’t completely
  x replace cellulose ether. But use HPG together with cellulose ether can get
  x better performance.

  ● When applied in gypsum based mortar, HPG can distinctly enhance
  x workability and ease of application.

  ● When applied in cement based mortar, HPG can replace cellulose ether with
  x equal quantity. HPG can endow cement based mortar with better anti-sagging,
  x thixotropy and ease of application.

  ●   Due to its cheaper price, end-users can get considerable cost-cutting.

JK-701 is nonionic hydroxypropyl guar derived from natural guar gum. It is developed to be applied in water paints,
latex paints.
JK-701 has a special rheology, which allows the user to reduce the sagging and spattering problems of paint products.
And it guarantees an excellent viscosity to improve film building and resist spattering of paint products.
We recommend the usage of JK-701 is determined by your own formulation. The normal usage level in paint is 0.3% to
1.0%.

Chemical name: Hydroxypropyl Guar
CAS Number: 32491-75-5
Applications:
JK-701S is nonionic hydroxypropyl guar derived from natural guar gum. It is developed to be applied in water paints,
latex paints.
JK-701S has a special rheology, which allows the user to reduce the sagging and spattering problems of paint products.
And it guarantees an excellent viscosity to improve film building and resist spattering of paint products.
In order to facilitate its dispersion in water, solubility of JK-701S is delayed by a surface treatment.
To develop its full viscosity, it is necessary to raise the solution pH up to 8~10, with a suitable alkali.
We recommend the usage of JK-701S is determined by your own formulation. The normal usage level in paint is 0.3%
to 1.0%.
