Acacia gums are hydrocolloids obtained without any chemical treatment. They are non-polluting, non-toxic and biodegradable. CNI supplies these products to non-food industries which use them as protective, film-forming, dispersing, suspending or adhesive agents:

  • Lithography
  • carbon-free copy paper
  • water-based paint and water colour
  • Office glue, cigarette paper, envelopes
  • electronic porcelain, electrotechnical ceramics, spark plugs, "ferrites" electronic components
  • fine porcelain
  • floatation (phosphates)
  • fire paste for matches, fireworks and explosives, black powder
  • Agricultural sprays, etc.

The result of state-of-the-art technological research by CNI, LITHOGUM™ is a polymer combination. Fully refined it does not require subsequent purification.

The performance of LITHOGUM as a desensitising, film-forming and protective agent is recognised in all printing processes: offset, lithography, silkscreen printing, diazo processes, aqua fortis and wetting solutions, sensitisation with dichromate, etc.

CM acacia gums like TECHNOGUM are more specifically designed for very varied technical applications. SPRAYGUM is recommended when the production process or use requires safe products when in contact with food.

CNI acacia gums like TECHNOGUM® are more specifically designed for very varied technical applications:

  • Carbon-free copy paper:
    TECHNOGUM® is used in micro-encapsulation processes with other colloides.

  • Electronic porcelain, electrotechnical ceramics, spark plugs, "ferrites" electronic components:
    The high and medium viscosity properties of TECHNOGUM® make it ideal when used for binding and integrity properties as it produces no polluting gas when baked.

  • Fine porcelain:
    TECHNOGUM® maintains integrity and absorbs water in a concentration in clay before going into the cast.

  • Ore floatation (phosphates):
    The high viscosity of the TECHNOGUM® depressing agent, in a I20g/MT dose, is ideal in the cascade floating process, aimed at separating ore from its gangue.

  • Fire paste for matches, fireworks and explosives, black powder:
    TECHNOGUM® is used in low concentrations (I-5%) in the composition of basic powder for its binding and adhesive, non-polluting and non-toxic qualities.

  • Agricultural sprays:
    As an emulsifying, stabilising, binding and film-forming agent, TECHNOGUM® solutions are able to delay water evaporation and are easily dispersed. Contained in spray formulas, the gums are particularly effective for the agricultural sector in pesticides, insecticides or fertilisers.

  • Seed Coating:
    As a suspension, film-forming and adhesive agent, TECHNOGUM® represents 3% of the active and working ingredients in seed coating.

GD

SPRAYGUM™ GD is an association of acacia gums purified and spraydried, specially designed for technical applications:

  • Water based paint and water color :
    SPRAYGUM™ GD, a plasticising, binding agent satisfying food contact standards, is used to stabilise pigments and colourings in proportions varying from 25 to 30% of the base paste.
  • Office glue, paper, envelopes :
    A solution of SPRAYGUM™ GD concentrated between 25 and 40% gives paper excellent natural, transparent and non-toxic adherence.
