Stoner TraSys® WB400 RotoFlow™

Stoner TraSys® WB400 RotoFlow™  is a mold release coating that facilitates the flow of polyolefin and nylon resin into the hard-to-reach areas of rotational molds. RotoFlow™  helps fill those areas around inserts, tight radii, threads, and deep cavities. This water-based release coating prevents pinhole bridging, thinning, blowholes, and static lines in the rotational molding process.  

Stoner TraSys® WB400 RotoFlow™ Advantages:
  • Removes pinholes, voids, and blowouts
  • Reduces scrap and increases productivity during the mold release process
  • Improves quality and consistency of rotomolded polyolefin, nylon, and cross-link parts
  • Increases the strength of inserts
  • Water-based, low-VOC formula
  • Compatible with PSI Brand Graphics
  • Improved appearance and operational performance of inserts
  • Contain no CFC or HCFC propellants or solvents

Stoner M520 ZIP-SLIP® 

Stoner M520 ZIP-SLIP®  is an excellent preventative mold cleaner when applied to the parting line of a rotational mold. ZIP-SLIP® eliminates any unwanted buildup of chemical resin on the mold's parting line that causes gaps, leaks, increased equipment maintenance, and prolonged cleanup time. ZIP-SLIP® improves efficiencies by maintaining a tighter seal on the parting line, which helps prevent pinholes, voids, and blowholes.

Stoner TraSys M520 ZIP-SLIP® Advantages:  
  • Maintains a tighter mold seal and reduces leaks
  • Eliminates unwanted buildup of resin in the parting line
  • Improves appearance and reduces defects caused by parting line gaps 
  • Colorless and nonstaining
  • Save time on equipment maintenance and cleanup

Stoner TraSys® 420 Mold Release

Stoner TraSys® 420 mold release coating is a clear water-based dispersion for rotational molding applications. When applied to a mold, it exhibits excellent release and antistick properties and has a very low coefficient of friction. It is clean, nonoily, nonstaining, and chemically inert, and it can function in high temperatures. 

Stoner TraSys® 420 Mold Release Advantages: 
  • Semipermanent mold release coating can provide multiple releases
  • Great for nylon, polyolefin, and cross-linked resin
  • Water-based formula with more strength and durability than a solvent-based release
  • It contains no alcohols that may form flammable vapors 
  • Unmatched capabilities as a durable lubricant mold coating

Stoner A320 Mold Cleaner

Stoner A320 mold cleaner is a water-based, concentrated cleaner for rotational molding applications. When applied, it efficiently cuts through the mold release, color build-up, grease, oil, dirt, stains and other tough grim.  This is a powerful, high pH concentrate cleaner that helps remove the left behind resin on rotational molds.

Stoner A320 Mold Cleaner Advantages: 
  • Reduces the need for sandblasting and breaking down molds
  • Quickly cleans and rapid stripping of mold residuals within seconds
  • Powerful, concentrated, water-based all-purpose cleaner for rotational molds
  • Safe for use on rotational mold applications, plastic, rubber, waxes and metal
