CONSTROMIT is a suitable blend of organic Hydro Colloids & is ready to use product.  CONSTROMIT is formulated by our Technical Experts keeping in mind Adhesion, Gellation  & Binding properties required to manufacture Construction Chemicals.

CONSTROMIT  is a unique product designed in a such a manner that it gives all the required properties like Water Retention, Thickening, Binding, Regulation of working time, Workability ,Open time etc.
CONSTROMIT   replaces all the expensive products like H.E.C.( Hydroxy Ethyl Cellulose ), Hydroxy Propyl Methyl Cellulose ( H.P.M.C. ) & other related products like Starches, Redispersible Powders etc.

CONSTROMIT  has properties which gives positive effect on open Time, & setting behaviour which results in  a noticeable increase in viscosity. When mixed with water it raises the viscosity by a factor of several thousands.


Physical Appearance : Fine Whitish Free Flowing Powder
Solubility in Water : Completely soluble in Water
Moisture Content : 10 %

Constrofix Binder is a white free flowing redispesible powder having pH 5 - 7,used in manufacturing of construction chemicals like tile adhesives,wall putties,etc.


Constrapel is a tailor made product  for water repellency & anti staining properties in construction materials like vitrified/porcelain tiles, gypsum boards, pavment tiles etc.

Constrapel develops its water repellant properties by reaction with air.

Applications  :

CONSTRAPEL is used in following products for water repellent properties:

- very effective as water repellent/ anti-staining agent for vitrified/porcelain tiles.
- Low-fired clay products immediately after they have been made e.g. roofing tiles.
- It is very effective for external Building walls, Brick walls , Pavement tiles & also for building foundation.
- Aerated Concretes
- Gypsum and gypsum-based Plasterboards

Storage Stability :

Constrapel should be stored in plastic drums. Constrapel has a shelf life of  12 months from the date of manufacturing.

Constrapel  should be always stored in normal temp ( above 0 C ) as it has a tendency to form crystals if stored in freezing temp.

If the  material is kept beyond recommended shelf life, it is not necessarily unusable but it is advisable to check the properties before use.

Processing :

Constrapel is ready to use product for water repellency application in construction industry. Constrapel is having different grades which are used as direct spray or it can be diluted with the water as per the final application. Like in vitrified/porcelain tiles it can be sprayed/applied on the tile surface immediately after the polishing application. For the best results of the final product it should be kept for drying for atleast 24 hrs & then the anti staining properties can be checked.

Packing :  Available in 50 kg plastic Drums.

Hydroxy Propyl Methyl Cellulose
Hydroxy Propyl Methyl Cellulose is nonionic cellulose ether polymer. It has uncommon & valuable composite physical & chemical properties according to different replacement degree of replacement group & modified degree.
Hydroxy Propyl Methyl Cellulose is an enteric film coating or a matrix Binder in solid forms. It is used as a viscosity control agent, Gelling agent , Film former, stabilizer, dispersant, lubricant, Binder, emulsifying agent & suspending agent in many industries .
It can dissolve in water at any ratio, their max. Concentration depends on their viscosity. It is nonionic polymer & hence will not act to metal salt & ionic organic compound, complex forming to insoluble precipitate.
When its water solution is heated to certain temp it will form a Gel & after cooling the formed gel becomes a solution again. It has a broad pH stability range ( 3-11) . It has Thickening power. It can make clean, pure, tough&tensile, flexible film& has excellent oil resistance. It has excellent bonding properties & can be used as bonding agent for pigment, tobacco products, paper, & coating.
It can prevent solid particles from precipitating thus inhibiting formation of deposition. It has better anti-enzyme ability & has long term viscosity stability.
It is a protective colloid & can prevent droplet & particles to be changed to agglomerate state. It is also used as emulsifying agent .
Appearance : White to off white free flowing Powder
pH : 5 8
Viscosity : 100000 cps ( 2 % solution )

Hydroxy Ethyl Cellulose (HEC A 200)
Hydroxy Ethyl Cellulose (HEC A 200) possesses trustworthy properties in respects of thickness promotion, emulsification, suspension, dispertion, cohesion, moisture keeping & anti-microbic fuction etc.
Nitin Chemicals/Nitin Specialites manufacture H.E.C. with various viscosities which finds various applications in suspension polystyrene, emulsion & new type acrylic resin emulsion paints, Colourful paint, construction chemicals, cosmetics, tooth paste manufacturing, ion exchange resin, daily use chemicals, textile printing & dying, & mintage machining, Gypsum board manufacturing etc.
HEC A 200 provides good properties in thickness promotion emulsification, suspension, dispersion, moisture resistance & anti-microbic function.
HEC A 200 is non-ionic therefore may be used safely with pH ranges between 2 to 12 & can give excellent compatibility with other compositional materials such as pigments, additives, salts, or electrolytes.
Products prepared with HEC is pseudo plastic, therefore possess excellent evenness while applied, without dropping or waving on surface. It is a very good film forming agent.
Important characteristic of H.E.C. A 200 :
  • HEC A200 itself is a thickner.
  • HEC A200 is a very effective binder in Paints.
  • HEC A200 has a good water holding capacity.
  • HEC A200 will give good coverage area when applied to surface.
  • HEC A200 will prevent sliding of Paints during the application stage.
  • HEC A200 has good adhesion properties which is useful in manufacturing of paints / construction chemicals.
  • HEC A200 is compatible with any pH ( 2 12) of pigments.
