Applications of HEC in Pharmaceuticals HEC finds extensive usage in the pharmaceutical industry, where it serves multiple purposes: Tablet Coatings HEC is commonly employed as a film-forming agent in tablet coatings. It provides a smooth and protective layer, facilitating easier swallowing and protecting the active ingredients from degradation. Controlled Drug Release Systems By utilizing the thickening and film-forming properties of HEC, pharmaceutical manufacturers develop controlled drug release systems. HEC-based matrices can control the release of active compounds, ensuring a sustained and prolonged effect. Ophthalmic Solutions HEC is used in ophthalmic solutions, such as eye drops and lubricants, due to its ability to enhance viscosity and provide a soothing effect. It aids in the retention of the solution on the ocular surface, promoting optimal therapeutic outcomes. HEC in Personal Care Products The personal care industry extensively utilizes  KDOCEL Hydroxyethyl Cellu...

Product Description Sulfonated melamine formaldehyde (SMF) is a Sulfonated Melamine Superplasticizer polymer used in cements and plaster based formulations to reduce water content, while increasing the fluidity and the workability of the mix. In concretes, addition of SMF in an appropriate mix design results in lower porosity, higher mechanical strength, and an improved resistance to aggressive environments. Category:   Superplasticizer ether (powder) HS Code:  3824401000 CAS:  64787-97-9 Sulfonated melamine formaldehyde (SMF) is used as an additive in all types of grouts, mortars, and as a component of concrete admixtures. Powdered superplasticizer is a spray dried powder with free flowing characteristics ideal for dry blending and water dissolution. Sulfonated melamine formaldehyde (SMF) is also an anionic polymeric dispersant that deflocculates the particle agglomerations that form when cement and water are combined. Dispersion of the cement causes a reduction in the ...

KDOCEL   Hydroxyethyl Cellulose   (HEC) is one kind of non-ionic soluble   cellulose ether , which can be dissolved in hot or cold water and has the characteristics of thickening, suspending, adhesive, emulsion, film forming, water retention and protective colloid etc., which is widely used in water based paints, following is our lab testing steps to make water based paints using HEC:  1. Add the prescribed amount of water, and add KDOCEL Hydroxyethyl Cellulose at a low speed of stirring, after Cellulose Ether dispersed, then add the prescribed amount of pH agent.     2. Add Bactericidal and mildew repellent agent, Dispersant, Defoamer, Glycol and other auxiliaries in sequence.    3. After dispersing and stirring evenly, increase the stirring speed and start to add pigments and fillers such as titanium dioxide and heavy calcium.  4. Disperse at high speed for 30-40 minutes, then reduce stirring speed, add emulsion, defoaming agent, Texanol ,p...

HPMC  can be divided into quick-dissolving (surface treated) and hot-dissolving (non-surface treated) types. The quick-dissolving product quickly disperses in cold water and disappears into the water. At this time, the liquid is not viscous, because HPMC is only dispersed in water, not really dissolved. About 2 minutes, the viscosity of the liquid gradually increases and forms a transparent viscous gel. For hot soluble type, it clumps in cold water, but in hot water, it disperses rapidly and disappears in hot water until the temperature drops to a certain temperature, then it slowly appears viscous until it forms a transparent viscous colloid. The reason for cold water caking is that the outer layer of cellulose powder encounters cold water and immediately starts to be viscous and thickens into a transparent colloid, while the cellulose inside does not come into contact with water and is surrounded by colloid, or is in powder form but slowly dissolves. In practice, hot water is not...
