Name: Celotech Celopro MK400 Hydroxypropyl Methylcellulose
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Celotech Celopro MK400 Hydroxypropyl Methylcellulose

Highly effective thickener with excellent pseudoplastic rheology for controlled flow and sag resistance.
Outstanding water retention capability—critical for extended workability in cementitious and gypsum-based systems.
Superior thermal gelation profile with reversible gel formation above 55–65 °C, enhancing heat stability during processing.
Consistent batch-to-batch performance due to stringent purification and standardized etherification control.
Low ash content and high purity, meeting stringent requirements for pharmaceutical and food-contact compliant formulations.

Typical Applications Of Celotech Celopro MK400 Hydroxypropyl Methylcellulose

Tile adhesives and grouts requiring extended open time and anti-sag performance.
Self-leveling underlayments where viscosity control and surface smoothness are essential.
Exterior insulation finishing systems (EIFS) demanding robust water retention and film-forming integrity.
Pharmaceutical tablet coatings and controlled-release matrix formulations.
Water-based architectural paints and texture coatings for improved spatter resistance and brush drag reduction.
