Hypro

Whatsapp Order

Hypro is a high-quality, non-ionic, water-soluble cellulose ether used primarily as a thickening, suspending, and stabilizing agent. It is derived from cellulose and chemically modified to achieve excellent water retention, rheological control, and film-forming properties. Hypro 88 is widely valued in industries such as construction, paints and coatings, adhesives, pharmaceuticals, and personal care for its ability to enhance texture, improve workability, and stabilize formulations.

Hypro

Primary Uses

Construction Industry

Used as a thickener and water retention agent in cementitious mortars, tile adhesives, plasters, and renders, improving workability and open time.
Enhances adhesion and flexibility of construction materials, reducing cracking and shrinkage.
Provides improved consistency and pumpability in cement-based formulations.

Paints and Coatings

Acts as a rheology modifier and thickener in water-based paints, coatings, and emulsions to optimize viscosity and application properties.
Stabilizes pigment dispersions and prevents settling and flocculation.
Improves sag resistance and brushability.

Adhesives and Sealants

Serves as a binder and thickener in water-based adhesives, improving bonding strength and film formation.
Enhances stability and consistency of adhesive formulations.

Pharmaceutical and Personal Care

Used as a thickening and suspending agent in topical gels, creams, and ointments.
Provides controlled viscosity and improved texture in eye drops, lotions, and other formulations.

Food Industry

Occasionally used as a stabilizer and thickener in certain food applications, following regulatory approval.

Secondary Uses

Oil & Gas Industry

Applied as a viscosifier and suspending agent in drilling fluids and hydraulic fracturing fluids.

Textile Industry

Employed as a thickener and binder in textile printing pastes and finishing products.

Ceramics and Paper

Used as a binder and rheology modifier in ceramic slip casting and paper coating formulations.
