Characteristics

1) Highly water soluble and hydrophilic

  • FOM-03010 dissolves in water at 50 wt% or more. It is easily soluble in solvents such as methanol and ethanol.
  • Due to the betaine structure, it exhibits very high hydrophilicity. (CLogP = -10)
イメージ

Many of the hydrophilic monomers currently on the market have CLogP values of around -2 to +1, which is an index of hydrophilicity/hydrophobicity.
FOM-03010 has a CLogP value of -10 and much higher hydrophilicity than these general-purpose monomers.

イメージ

Also in the LogD value, which is a hydrophilicity index considering the dissociation of molecules under different pH environments, FOM-03010 shows high hydrophilicity with LogD = -4 (pH = 7).

Applications

Imparting biocompatibility to various products

Examples:Medical devices, materials for analytical instruments, materials for bioengineering

Hydrophilic/antifouling coating

Examples:Separating film, analytical instruments, building materials, water-absorbing materials, fibers, household products, cleaning agents

Water retaining/moisturizing materials

Examples:Additives for cosmetics and toiletry products, civil engineering materials, sanitary goods

Control of hydrophilicity/hydrophobicity of various cured components

Examples:Paint, coating, kneaded and molded products, printing materials, gel, drug formulation materials

Usage example

  • A functional coat with a high hydrophilicity can be formed.
  • Due to the high water solubility of the monomer and initiator, a coat solution can be prepared using water as a solvent.

Water soluble monomer (FOM-03010) 67
Water soluble light radical initiator (FOM-03011) 3
Methanol 400

Usage example and physical characteristics of Coat A

  • Apply to PET substrate, dry (50°C/5 min), and then photocure (3 J/cm2)

※Lamp used: High pressure mercury lamp (Exposure is controlled as UV-A)

Coats evaluated Water contact angle (°)
PET alone 75
Coat A 35
Impregnate Coat A with water and dry 44

In evaluation of wettability by water contact angle showing affinity with water, Coat A exhibits high hydrophilicity with a low contact angle, and maintains the hydrophilicity even when it is re-dried after being impregnated with water.
