Iron Oxide Pigments
 

SunferroxTM inorganic iron oxide pigments are chemically inert and stable in all weather conditions. They are safe, non-toxic colours with excellent resistance to UV radiation, fading and leaching, and are virtually maintenance-free.

Coloured Concrete and asphalt materials serve as methods of demarcation, design and beautification in several constructions. Our product's performance is consistent across the wide variety of shapes of coloured concrete materials. SunferroxTM iron oxide pigments can not only be used to add colour but also to meet the highest demands for colourfastness and weather resistance.

Generally, iron oxide pigments are resistant to alkalis and are characterized by high colouring power, which is case of SunferroxTM is guaranteed by no filler usage and their inherent synthetic origin. Additionally, a short agitation time is required for wet mixtures, and use SunferroxTM pigments gives an optimum homogenization of the product.

Cellulose Ethers
 

CennloseTM cellulose ethers are water-soluble polymers derived from cellulose, the most abundant naturally available polymer. Cellulose unlike any other types of natural polymers, such as starch and gums, fails to dissolve in water. CennloseTM cellulose ethers when dissolved in water, offers a variety of functions such as thickening, surface activity, protective colloid, water retention, shape retention, etc. These functions can be used in a wide variety of industries.

The water retention and protective colloid properties of CennloseTM are especially useful in the construction industry, as mixing of cellulose ethers into building materials can improve operation properties of the material and increase the efficiency and quality of the same. Use of CennloseTM has also shown to improve the properties for masonry mortars, plasters, and water-proofing mortars.

Divnova offers the following range of cellulose ethers under the CennloseTM brand, specifically for the building and construction industry:

Cellulose Ethers

Viscosity Range (mPa.s) Viscosity Range (mPa.s)
Hydroxypropyl methyl Cellulose (HPMC) 400 – 1,00,000
Methyl Hydroxyethyl Cellulose (MHEC) 5 – 1,00,000

CennloseTM HP cellulose ethers series products helps building materials application with more ease and increased performance.

  • Increased water retention
  • Decreased water usage
  • Stability in formulations with low water content
  • Increased cohesiveness
  • Greater thickening control
  • Sag resistance
  • Increased workability
  • Increased material strength

Different grades are chemically and physically optimized for adjusting and controlling specific properties of dry mortars and building products (cement and gypsum based).

CennloseTM HP series cellulose ethers’ quality is well qualified in the industry and special care is taken to continually provide our customers with best-in-market products and service.

Redispersible Polymers
 

AccopolTM are water-redispersible polymer products, produced by spray-drying of aqueous polymer dispersions (latex). Once a latex powder containing dry mortar is mixed with water, latex powder particles redisperse, desagglomerating into small elementary particles.

AccopolTM has applications in thermal insulations, wall putty, water-proofing cementitious slurries, and tile adhesives. Depending on application the AccopolTM of latex powders are available as co-polymers of:

  1. Vinyl Acetate and Ethylene
  2. Vinyl Acetate and VEOVA
  3. Vinyl Acetate, Acrylic and VEOVA
  4. Vinyl Chloride, Vinyl Acetate, and Ethylene

Incorporation of AccopolTM latex powders enhances the properties of cement or gypsum based formulations:

Before Setting After Setting

The inherent properties and single component packaging allows for higher cost savings compared to liquid polymers.

AccopolTM is made in a ISO 9001:2000 certified plant meeting the highest quality standards.
