Application Advice

Dissolving:

  • MCT5 is soluble in many organic solvents such as esters, ketones, aromatic hydrocarbons, and lower alcohols. By using water and either a fixed or fugitive alkali, an aqueous solution of MCT5 can be prepared. Solutions of solid content up to 50% can be made by incorporating a proportion of a lower alcohol such as methanol, ethanol, or isopropanol (IPA).

Melt:

  • MCT5 is thermoplastic and will gradually soften and flow with increasing temperature.
  • Heat activated coatings and adhesives can also be easily formulated, which show excellent adhesion to metal surfaces.

Compatibility:

  • MCT5 is compatible with other M Grade polymers, and can be mixed in any proportion to modify either solution or dry film properties.
  • MCT5 can be plasticized with many types of plasticizer to modify film properties.

Applications: 

  • Solvent-based adhesives, solvent-based inks & lamination adhesives, heat seal adhesives, alkali removable coatings, pigment dispersion, paper impregnation for automotive filters, hot stamping foils.

Storage & Handling

Storage Conditions
  • MCT5 is a thermoplastic solid. To prevent sticking of the polymer granules, the product should be stored in dry conditions, below +20°C (+68°F), out of direct sunlight.
  • Pallets should not be stacked.
  • Under these conditions, MCT5 has a storage life of at least 24 monthsfrom date of manufacture.
  • MCT5 which has been stored for longer than 24 months should be tested before use.
