Specifications of Low Viscosity Hydroxypropyl Methyl Cellulose HPMC E5 for Coating Applications

Descripción Nxoge ar producto

HPMC E5 is a low-viscosity grade of hydroxypropyl methyl cellulose. It dissolves easily in cold water and forms clear, stable solutions. This makes it ideal for use in film coatings for tablets and capsules. The product meets pharmacopeial standards including USP-NF, Ph. Eur., ne JP.

Key Physical Properties

Viscosidad: 4–6 mPa·s (measured at 2% njäts'i, 20°C)
Methoxyl content: 19–24%
Hydroxypropoxyl content: 4–12%
pH (2% njäts'i): 4.0–8.0
Moisture content: ≤5%
Ash content: ≤1.5%

Performance in Coating Systems

HPMC E5 gives smooth, uniform films with good adhesion to tablet surfaces. It dries quickly during the coating process, which helps reduce production time. The polymer does not require organic solvents—water alone is enough for dissolution. This supports safer, more environmentally friendly manufacturing. Films made with HPMC E5 are flexible and resist cracking under normal handling conditions. They also allow controlled release of active ingredients when needed.

Manejo ne almacenamiento

Store HPMC E5 in a cool, lugar seco ya'bu̲ ar hyadi directa. Keep containers tightly closed to prevent moisture absorption. The material remains stable for up to 36 Ya zänä nu'bu̲ ar almacena correctamente. Avoid contact with strong oxidizing agents. Use standard industrial hygiene practices during handling.

Regulatory Compliance

This grade complies with current Good Manufacturing Practice (cGMP) guidelines. It is suitable for use in pharmaceutical products approved by major regulatory agencies worldwide. Certificates of Analysis and Compliance are available upon request.

Applications of Low Viscosity Hydroxypropyl Methyl Cellulose HPMC E5 for Coating Applications

Applications of Low Viscosity Hydroxypropyl Methyl Cellulose HPMC E5 in Coating Systems

Enhanced Film Formation and Surface Smoothness

Low viscosity HPMC E5 works well in water-based coating systems. It helps form smooth, even films during drying. The polymer dissolves quickly in cold water, which makes mixing easy and fast. This leads to better surface uniformity and fewer defects like streaks or bubbles.

Improved Workability and Application Performance

Coatings with HPMC E5 show good flow and leveling. Painters find these products easier to apply with brushes, rodillos, Wa pulverizadores.. The additive reduces splatter and drag, giving a cleaner finish. It also keeps pigments and fillers evenly suspended, so the mixture stays stable over time.

Strong Adhesion and Durability

HPMC E5 boosts adhesion to common surfaces such as drywall, c, and masonry. It forms a flexible film that moves slightly with temperature changes. This flexibility helps prevent cracking or peeling under stress. The coating remains intact longer, even in humid or changing conditions.

Water Retention for Better Curing

In cement-based or plaster coatings, HPMC E5 holds water in the mix. This gives cement particles more time to hydrate fully. r, the final layer gains better strength and bonds more tightly to the substrate. Reduced water loss also means fewer surface flaws like pinholes or dusting.

Compatibility and Stability

HPMC E5 mixes well with other common ingredients in coatings—such as thickeners, dispersantes, ne conservantes. It does not react badly with most additives. The solution stays clear and consistent, even after long storage. This reliability helps manufacturers keep production smooth and reduce waste.

5 FAQs of Low Viscosity Hydroxypropyl Methyl Cellulose HPMC E5 for Coating Applications

Frequently Asked Questions: Low Viscosity HPMC E5 for Coating Applications

What is HPMC E5?

HPMC E5 is a type of hydroxypropyl methyl cellulose with very low viscosity. It dissolves easily in cold water and forms a clear, smooth solution. This grade is often used in coating applications where light film formation and good flow are needed.

Why choose low viscosity HPMC for coatings?

Low viscosity HPMC spreads evenly on surfaces. It helps the coating mix stay stable and prevents ingredients from separating. The thin consistency also makes spraying or brushing easier without clogging tools.

How does HPMC E5 improve coating performance?

HPMC E5 acts as a binder and thickener. It holds solid particles together and sticks them to the surface. It also slows down water loss, giving more time for the coating to level out and dry smoothly. This reduces cracks and improves finish quality.

Is HPMC E5 safe for use in coatings?

Hä. HPMC E5 is non-toxic and widely approved for use in pharmaceuticals, nts'i, and construction products. It does not react with other common coating ingredients. Always follow safety instructions on the product label.

How should HPMC E5 be mixed into a coating formula?

Add HPMC E5 slowly to cold water while stirring. Let it hydrate fully before adding other ingredients. Avoid using hot water—it can cause clumping. Proper mixing ensures even distribution and full performance benefits in the final coating.
