Walocel 228 or METHOCEL™ 228 is a hydroxypropyl methyl cellulose (HPMC) designed for use in tape joint compounds, crack fillers and similar construction materials. A cold water dispersible cellulose ether, Walocel 228 is a low viscosity thickener with slightly delayed solubility. It imparts good workability and excellent crack resistance, and reduces lump formation. It also enhances water retention.
