China [CN] GOODCELTM HPMC is mainly used to construction drymixed mortars, which improves multi-beneficial performance during the use of wet mortars. It provides the following benefits:
● Supply thickening & suspension performance
● Outstanding water retention
● Improve workability
● Prolong open time
● Improve anti-slip and anti-sag
● Odorless, tasteless
GOODCELTM HPMC may be used in a variety of cement based, gypsum based
and lime based building drymixed mortars as follows:
● Skim coat, plasters, renders
● CTA & CTG, repair mortar
● EIFS adhesive mortar & base coat
● Stucco and decorative mortars
● Masonry mortars
