Features & Benefits

  • Easier to disperse in formulations prior to hydration
  • Water soluble
  • No ionic charge
  • pH stable (2–13)
  • Thermal gelation
  • Gels go back into solution upon cooling
  • Rheology modifier
  • Excellent control over rheology at low concentrations

Problems Solved

Difficulty with thickening formulations using non-surface-treated METHOCEL™ grades
Unstable solution viscosity caused by extreme pH conditions
Splattering of paints and coatings when applied to surfaces
Instability of paint, coating, adhesive, and cleaning formulations
Dripping and sagging of paints, coatings, adhesives, and cleaners on vertical and overhead surfaces

Applications

METHOCEL™ K15MS is an ideal thickener for most coating, adhesive, and cleaner applications. METHOCEL™ K15MS will also reversibly gel at temperatures above 90°C and boost green strength to ceramics and adhesives. Surface-treated grades like METHOCEL™ K15MS are often used as thickeners in water-based architectural paints that also provide shear-thinning properties. They are easy to disperse, offer precise viscosity control, improve dried film durability, and increase shelf life. In addition, latex paints thickened with METHOCEL™ K15MS exhibit good spread, flow, and leveling.

METHOCEL™ K15MS provides delayed dissolution for adhesives, gel packs, and drilling fluids. It also can be used in asphalt emulsions and plastic injection processes.
