Hydroxypropyl Starch ether (HPS)
MELOTEL HPS is extracted from natural plants, with the same chemical structure and similar properties compared with HPMC that not only provide HPMC-like function,but also has good compatibility with other building additives.
Used in building mortar, starch ether can significantly increase the consistency of mortar and improve the construction performance and sag resistance of mortar. Starch ether is usually used in conjunction with non-modified and modified cellulose ethers. It is suitable for both neutral and alkaline systems, and compatible with most of the additives in gypsum and cement products, such as surfactants, HPMC, starch and polyvinyl acetate and other water-soluble polymers.
In combination with HPMC,MELOTEL HPS can play a better thickening effect,with better crack resistance and improve workability.And by adding starch ether ,the cost of the mortar formulation can be significantly reduced.
