Hydroxypropyl Starch Ether (HPS)

Grade: Construction Grade Modified Starch

Brobond HPS is a modified plant-based starch ether. When blended into drymix formulas alongside MHEC or RDP, it prevents heavy tile slippage, eliminates mortar slumping on high walls, improves yield, and lowers overall formulation cost.

Packaging & Supply: Supplied in standard 25 Kg Multi-wall Bags. Bulk palletized container orders and customized shipments available.
