Inks, Paints & Coatings

We manufacture a variety of coating chemicals in India such as stabilisers, curing agents, dispersing agents as well as solvents to help improve the overall performance of virtually every kind of coating product in the ink and coating industry.

CRISTOL™ surface-active agents (surfactants) provide properties that are necessary to wet, disperse and suspend pigments in coating formulations effectively rendering a superior performance edge. Specific agents include:

  • Emulsifier for Emulsion Polymerisation
  • Pigment Dispersants
  • Flow & Levelling Agents
  • Grinding Aids
  • Wetting Agents

CRISTOL™ range of speciality surfactants were developed specifically to incorporate versatility and ease of use. A representative selection of CRISTOL™ surfactants is described on the following pages. More data can be found in CRISTOL™ product bulletins, product specification sheets and material safety data sheet.

KAPL effectively provides your paints and coatings with superior performance edge.

Surfactant for Emulsion Polymerisation

Krishna Antioxidant Private Limited (KAPL) offers a range of non-ionic and anionic CRISTOL™ surfactants for emulsion polymerisation industry. The emulsion polymer system uses a variety of surface-active agents to disperse reactive monomer in water and to stabilise the resulting polymer latex. Anionic surfactants are blended with non-ionic surfactants to improve latex stability.

Every emulsion polymer has its own proprietary formulation and in-depth knowledge of the applications for a particular latex. The physical data and properties of CRISTOL™ surfactants for emulsion polymerisation may enable the polymer producer to make an effective selection of surfactants.

Dispersants

CRISTOMER DISPERSANTS offered by KAPL should not be confused with the more familiar wetting agents or surfactants and they are quite different. Unlike surfactants,

CRISTOMER DISPERSANTS will not emulsify liquids.
Another more relevant difference arises due to the design of CRISTOMER DISPERSANTS, as they are of much higher molecular weight. Unlike classical surfactants, they are more inert and have no adverse effects on durability. Indeed, in many applications, such as automotive finishes, durability has been enhanced when

CRISTOMER DISPERSANTS have been used.
Coatings made from these dispersants will exhibit better viscosity stability, particularly on storage, excellent gloss and flocculation, resistance and less colour change on exposure to weathering.

It is therefore important to optimise the dispersion process and to use CRISTOMER DISPERSANTS efficiently in order to ensure that high quality formulations are produced.

Wetting, Flow & Levelling Agents

Wetting the pigment particles is essential for them to be finely distributed in liquid. Air entrapped in the pigment powder must be fully removed and the pigment particle completely surrounded by the liquid medium.
Wetting agents are important to impart excellent wetability to the pigments enhancing their dispersion in the emulsion based paints and the overall stability of the paint.
These additives are useful in preventing the accumulation of concentration of pigments at the surface of the paint (floating) or in stains and patches inside the coating film (flooding). This defect leads to a change in color.

Formulation Aids

Stabilizers prevent thermolytical polymer decomposition during production (for example in powder coatings) or processing (stoving systems), and provide long term heat stability.


KAPL stabilizers act as radical scavengers and showing high extraction resistance.


Coalescing agents are used in dispersion paints for optimizing the film formation process of the polymeric binder particles. The film formation process in dispersion paints involves the coalescence of the polymeric particles, during and after the evaporation of the diluents (notably water), thereby permitting contact and fusion of adjacent polymeric dispersion particles.


KAPL easily dispersible defoamer is used in waterborne coatings like dispersion paints as well as in aqueous inks and pigment dispersions.


CRISTOL Defoamers are extremely versatile in application and efficient in various waterborne systems for defoaming and anti-foaming purposes during manufacturing and application.
