HP 400


HP 400 is a high-performance industrial-grade hydroxypropyl methylcellulose (HPMC) specifically developed for self-leveling mortar applications. As a premium cellulose additive, HP 400 has excellent water retention capacity, which prevents rapid water loss of mortar during construction. This avoids cracks caused by premature drying and ensures sufficient hydration of cementitious materials. HP 400's outstanding thickening properties ensure the mortar maintains a stable consistency for smooth application.
HP 400 is ideal for self-levelling mortar, which requires high fluidity to form a flat, smooth and robust base under its own weight.
