Name: Ashland LHB550C Cellulose Ether
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Ashland LHB550C Cellulose Ether

High viscosity build and excellent pseudoplastic rheology for superior workability and sag resistance.
Outstanding water retention performance, critical for extended open time in cementitious systems.
Enhanced compatibility with common admixtures including superplasticizers and retarders.
Consistent batch-to-batch performance ensured by Ashland’s stringent GMP-compliant manufacturing controls.
Low foam generation during high-shear mixing, minimizing entrapped air in final formulations.

Typical Applications Of Ashland LHB550C Cellulose Ether

Cement-based tile adhesives (C2TES, C2TE, C1T classifications per EN 12004).
Exterior insulation finishing systems (EIFS) base coats and finish coats.
Self-leveling underlayments (SLU) requiring controlled flow and edge stability.
Repair mortars and grouts where extended working time and reduced cracking are essential.
Decorative stucco and textured exterior renders.
