Internal Mold Releases

 

MARBALEASE® IMR Internal Mold Releases

Marbalease® IMR Internal Mold Releases are blends of polymers that form a mold release when added to a thermoset resin system in the pultrusion process. Added to thermosets and rubbers at 0.1-2.0 % levels by neat resin weight, these products can -

  • improve productivity with better demolding
  • provide less tool down time and better looking parts
  • reduce resin viscosity facilitating resin flow
  • improve fiber impregnation
  • improve wetting of tool surfaces
  • provide antistatic properties
  • parts exit ready for painting, bonding or other post-finishing without degreasing
  • also useful in stubborn demolding situations with open molding, RTM and filament winding operations when used with external mold releases
  • Marbalease® IMR Internal Mold Releases contain no wax, silicone or metallic stearates and do not affect part color
  • Unregulated for shipping: non-flammable, non-hazardous

MARBALEASE® IMR-1 Internal Mold Release – Polyester, Vinylester & Phenolic Pultrusion Resins

Marbalease® IMR-1 Internal Mold Release is a liquid process aid for use in the pultrusion thermoset composite production method with Polyester, Vinylester and diallyl phthalate phenolic (DAP) pultrusion resins. Typically added at rates of 0.75 – 2.0% to the pultrusion resin formulation, MARBALEASE® IMR-1 Internal Mold Release aids the release of pultruded composite from the die wall as the composite moves through the die. With a superior neutralization package it offers corrosion resistance to metal dies and improved processing. Contains no wax, silicone or metallic stearates. Benefits can include improved part mechanical and cosmetic properties by improving wetting of the reinforcement, better dispersion of fillers and other additives, reduced matrix viscosity, enhanced antistatic properties, and lower pulling force requirements during processing of pultruded composites. MARBALEASE® IMR-1 Internal Mold Release is a non-exuding polymeric blend of phosphate esters, fatty amines, and fatty acids, allowing parts to emerge ready for post-finishing without solvent wash or abrasion. MARBALEASE® IMR-1 Internal Mold Release is specified for or use with polyester and vinylester resins using BPO, Peroxydicarbonates and esters, TBPB, Dicumyl Peroxides, and Peroxyketal Peroxides; and with diallyl phthalate phenolic (DAP) resin.

Effective within a range of 0.75 to 2.0 parts per 100 parts neat resin by weight. Heavily loaded matrices may require a higher percentage of Marbalease® IMR Internal Mold Releases.

Mix with resin prior to addition of catalyst, fillers and other resin additives.

This product can improve productivity, promote better demolding, gives less tool down time and better looking parts.

Also useful when mixed into thermoplastics and rubbers at 0.1 – 1.0% wt.

MARBALEASE® IMR-2 Internal Mold Release – Epoxy Pultrusion Resins

Marbalease® IMR-2 Internal Mold Release is a liquid process aid additive for use in the pultrusion thermoset composite production method using Epoxy resins. Especially recommended for amine cured systems. Typically added at rates of 0.5 – 2.0% to the pultrusion resin formulation, MARBALEASE® IMR-2 Internal Mold Release aids the release of pultruded composite from the die wall as the composite moves through the die. It contains no wax, silicone or metallic stearates. Benefits can include improved part mechanical and cosmetic properties by improving wetting of the reinforcement, better dispersion of fillers and other additives, reduced matrix viscosity, enhanced antistatic properties, and lower pulling force requirements during processing of pultruded composites. MARBALEASE® IMR-2 Internal Mold Release is a non-exuding polymeric blend of fatty acids and amines, allowing parts to emerge ready for post-finishing without solvent wash or abrasion.

MARBALEASE® IMR-3 Internal Mold Release – Phenolic Pultrusion Resins

Marbalease® IMR-3 Internal Mold Release is a liquid process aid for use in the pultrusion thermoset composite production method with phenolic resins. Added at rates of 0.5 – 2.0% to the pultrusion resin formulation, Marbalease® IMR-3 Internal Mold Release aids the release of pultruded composite from the die wall as the composite moves through the die. With a superior neutralization package it offers corrosion resistance to metal dies and improved processing. Contains no wax, silicone or metallic stearates.

Benefits can include –

  • improved part mechanical and cosmetic properties by improving wetting of the reinforcement
  • better dispersion of fillers and other additives
  • reduced matrix viscosity
  • enhanced antistatic properties
  • lower pulling force requirements during processing of pultruded composites
  • parts to emerge ready for post-finishing, coating or bonding
  • decreased die wear

Marbalease® IMR-3 Internal Mold Release is a non-exuding polymeric blend of phosphate esters, fatty amines, and fatty acids, allowing parts to emerge ready for post-finishing without solvent wash or abrasion. Also used in conjunction with external mold releases to ease difficult demolding in open molding, RTM and filament winding.
