2. Hydrophobic Additives These additives repel water, providing hydrophobic properties to the mortar. This is essential for outdoor applications where moisture exposure is high. By using hydrophobic additives, masonry work can resist water infiltration, which can lead to deterioration over time.

The distinct properties of HPMC contribute to its widespread popularity across various industries. Key benefits include

Hydroxyethyl cellulose (HEC) is a water-soluble polymer derived from cellulose, a natural component of plant cell walls. This versatile compound is widely used in various industries due to its unique properties, making it a critical ingredient in applications ranging from personal care products to construction materials and pharmaceuticals.

Degree of Substitution

From an environmental perspective, MHEC stands out as it is derived from renewable resources — namely, cellulose sourced from plants. Its biodegradability contributes to a lower environmental impact compared to many synthetic alternatives. Furthermore, MHEC is generally recognized as safe (GRAS) by health authorities when used as a food additive, which renders it a preferred choice across industries seeking to maintain consumer safety.

Hydroxyethyl Cellulose is a white, free-flowing granular powder, prepared from the alkali cellulose and ethylene oxide (or ethylene chlorohydrin) by etherification, and belongs to non-ionic soluble cellulose ethers, both soluble in hot and cold water. Owing to good thickening, suspending, dispersing, emulsifying, film-forming, water-protecting and providing protective colloid properties, Hydroxyethyl Cellulose has been widely used in oil exploitation, coating, building, medicine, food, textile, papermaking, polymerization and other fields.

The chemical formula of hydroxyethyl cellulose is (C2H6O2)n, where n indicates the degree of polymerization and can vary widely depending on the manufacturing process. HEC is identified by the CAS number 9004-62-0. This unique identifier helps researchers, manufacturers, and regulatory bodies to catalog and reference the compound accurately.
