Applications
1). Papermaking industry: Hydroxypropyl starch is used for internal sizing and surface sizing of paper to make the film smooth and reduce ink consumption.
2). Textile industry: Hydroxypropyl starch can be used as warp slurry to improve the wear resistance and weaving efficiency during weaving. Hydroxypropyl starch with a high degree of substitution can be used as printing paste.
3). Oil drilling industry: Stabilize well walls, improve drilling conditions, prevent collapse, flocculate drilling cuttings, etc.
4). Daily chemical industry: Hydroxypropyl starch is used as adhesive, suspending agent and thickener in daily chemical industry, cosmetics or coatings.
5). In building materials: Hydroxypropyl starch can be used as an adhesive, coating or gelling agent for organic liquids in building materials.
Various types of (cement, gypsum, gray calcium based) interior and exterior wall putty additives.
Various types of facing mortar and plastering mortar additives.
As a molding adhesive in various types of plaster, ceramics and porcelain products.
It has good thickening and stability, and plays the role of suspension and emulsification in aqueous solution.
Storage: Store in a dry, clean environment, away from heat and fire. Unused product must be kept sealed after opening.
