Properties / Benefits
GOODCEL GPK provides the following benefits:

• Supply thickening & suspension performance
• Outstanding water retention
• Improve workability
• Prolong open time
• anti-enzyme, odorless, tasteless

Application

• Skim coat, Plasters, renders
• CTA & CTG, Repair mortar
• EIFS adhesive mortar & base coat
• Stucco and all kinds of decorative mortar
• Masonry mortars

Dosage and Handling
GOODCEL GPK is added to other powdery components and mix to get a homogenous formulation. The dosage may vary from 0.1%*0.3% of the total dry material by weight. The actual required dosage should be evaluated in suitable tests prior to final application.

Storage
GOODCEL GPK may be stored in sealed bags under dry cool place for at least *2 month. The product is hygroscopic. In case of high-viscosity grades, a slow loss of viscosity would be measured after long-term storage (>1 year). Once package is opened, it must be resealed and kept tightly closed to avoid absorbing water from moist air.

Package
*5kg/bag: multiply paper or plastic woven bag with polyethylene interlayer
