Barisol(Barium Sulphate)

Barisol(Barium Sulphate)is chemically synthetic Barium Sulphate with modified surface. The chemical is snow white in color and gives good shade and brightness to the product it is used in. The ultra fine particles act as a spacer for prime pigments and hence contribute to the hiding with very high gloss in end application.

Paint & Pigments
Barisol(Barium Sulphate)or Blanc Fixe is used in industrial paints and its good mechanical properties makes it a high quality functional extender for standard powder coating systems. The chemical is suitable for the cost optimization of formulations via increased hiding power and possible partial replacement of pigments.
  1. Good loading properties
  2. Good rheological properties
  3. Excellent compatibility with colored pigments
Natural Properties of Barisol(Barium Sulphate) or Blanc Fixe:
  1. Resistant to acids and alkalis
  2. Insoluble in water and organic solvents
  3. An inert product which is lightfast
  4. Weather resistant
  5. Colour neutral, due to its low refractive index
  6. Extremely narrow particle size range for high gloss specifications
  7. Extremely good wettability due to low specific surface area
  8. Low abrasion during processing, due to low Mohs hardness

Automotive Paint Systems
For use in ex-tender systems, due to gloss retention and excellent mechanical properties.

High Solids Paints: Partial substitution of Sachtleben micro for other pigments achieves significant reduction of volatile matters.

Due to its chemical resistance to acids and alkalis (e.g. acid-glued papers), BARISOL (BARIUM SULPHATE) OR BLANC FIXE is particularly suitable for use as a filler in the pulp. For use in black and colored pigmented, wax and resin impregnated papers, thanks to its color neutrality. Blanc Fixe has a beneficial effect on porosity (reduction of mottling). Can also be used as a pigment in paper sizes, with a high whiteness. Plastics and rubber For use as an extender in color sensitive thermoplastics systems and for high gloss plastic surfaces. Also suitable for use in glazes and impregnation agents, grinding pastes, lubricants and separating agents, additives and soaps.

Decorative Papers : By expelling air in the pores. More uniform resin penetration and reduction of mottling in colored decorative papers.

Ideal Properties for Paper Making: High whiteness, gloss and good printability (in cardboard and paperboard sizes, Heaviness increases the GSM of paper.

Plastics and Rubber Thermoplastics: Enhances the efficiency of coloured pigments in master batches and pastes. imparts a feeling of quality and luxury. Has a positive effect on mechanical and visual properties, in particular impact strength and gloss, in thermoplastic compounds. Elastomers: Particularly suitable as an extender, since free of rubber effects on storage stability and resistance to aging.

Diatomaceous Earth Powder

Caltron's diatomaceous earth powder is very effective for bed bugs treatment, pest and ticks treatment. It is 100% safe for use and non toxic. Being food grade It certainly ensures safety and hygiene. Used by many throughout India and abroad with high success rate, this product is certainly very effective and economical.

Caltron's Diatom Powder food grade for bed bugs/ pest/ ticks is made from the fossilized remains of tiny, aquatic organisms called diatoms. Their skeletons are made of a natural substance called silica. Over a long period of time, diatoms accumulated in the sediment of rivers, streams, lakes, and oceans.

How does Caltron's Diatomaceous earth work?
Caltron's Diatom Powder food grade for bed bugs/ pest/ ticks is not poisonous; it does not have to be eaten in order to be effective. Diatomaceous earth (DE POWDER) causes insects to dry out and die by absorbing the oils and fats from the cuticle of the insect's exoskeleton. Its sharp edges are abrasive, speeding up the process. The diatomaceous earth powder dries up the water content and forces the bugs to dehydrate and die. It remains effective as long as it is kept dry and undisturbed.

What Types of Critters is DE Useful On?
DE - both food grade and forms containing additional pesticides - is effective on anything with an exoskeleton. This means insects (anything with six legs) and non-insect arthropods (eight or more legs). Crawling and hiding insect, spider, and scorpion pests will contact crack and crevice treatments, so DE is an excellent option for these areas.

Some Unknown Facts:
Bed bugs are persistent.  Eradicating, exterminating or just killing an entire infestation requires persistence.
  • Bed bugs can hide in extremely small cracks and crevices making it difficult to locate breeding sites.
  • Bedbugs are rarely seen in daylight. They emerge from their hiding spots at night.
  • Bed bugs can live a year or longer without food¬† (blood) and thus stay in their hiding places.
  • Bed bugs can travel long distances and survive in suitcases, clothing, vehicles, aircraft, cruise ships and other modes of transportation.
  • Bed bug females lay about 300 eggs.
  • Bed bugs hatch from eggs in 10 days.

Bed Bug Bites
  • Bed bugs feed by piercing skin with an elongated beak.
  • Saliva is injected, containing an anesthetic to reduce pain, and an anticoagulant to keep blood flowing.
  • The reaction to bed bug bites varies among individuals, from no reaction to sever skin inflammation and irritation.
