Types Of HEMC For Mortars

The HPMC for wall puttys produced by our company mainly include the following types:

Construction Grade HPMC

Hydroxypropyl methyl cellulose (HPMC for short) is an important mixed ether, a non-ionic water-soluble polymer, widely used in food, medicine, daily chemical, coatings, polymerization reaction and construction fields as dispersion suspension, thickening, emulsifying, stabilizing and adhesive.

Cellulose Ether HPMC

These products are used in textile industry as thickener, lens, mucus, oil-resistant coating, filler, emulsifier and stabilizer. Also widely used in industries such as synthetic resin, petrochemicals, ceramics, paper, leather, medicine, food and cosmetics.

HPMC For Wall Putty Advantages

Excellent Water Retention

HPMC is a reliable and consistent ingredient for creating a uniform putty solution ready for application. It is created to ensure enough moisture remains in the substrate and achieve full hydration.

Increase Operationality

HPMC is a highly efficient ingredient that dissolves rapidly in cold water. It increases the solution’s viscosity. As it has a hydrophilic nature, HPMC can also extend working time. Consequently, waiting times are shortened, and productivity is increased.

Enhance Workability

HPMC offers superior thickening, dispersion, and film-forming capabilities. It reduces moisture evaporation during wall putty application. And it greatly improves work efficiency. Thus, HPMC is an ideal selection for wall putty applications.

Sag Resistance

HPMC for wall putty excels in preventing drips and sags. It keeps wall putty firmly in place on vertical surfaces, ensuring a smooth finish for your wall putty projects. Whether you’re a professional or a DIY enthusiast, HPMC simplifies your work.

Applications of HPMC For Wall Putty

Thickener

Using HPMC in putty powder can thicken putty powder to enhance its suspension ability, anti-sagging ability as well as keep the solution uniform.

Water–retentioner

Using HPMC in putty powder can keep it in a moist state and make the auxiliary ash calcium react to underwater action.

Lubricant

Hydroxypropyl Methyl Cellulose has a lubricating effect. Using HPMC in putty powder can make the putty powder have good workability and keep it smooth during the construction process, saving manpower.

Mixing Precautions of HPMC For Wall Putty

Water-to-Powder Ratio
Follow the instructions on the packaging to determine the correct water-to-powder ratio.
Avoid adding too little water, as it makes the putty too thick and difficult to spread, reducing HPMC’s water-retaining efficiency.
Avoid excessive water, which makes the putty too thin, prone to dripping, and weakens adhesion.

Mixing Process
Pour water into a clean container, then gradually add the putty powder.
Start the electric mixer at a moderate speed and mix for 5–10 minutes until the mixture is smooth, free of lumps, and forms a paste.
Proper mixing ensures HPMC fully dissolves and enhances the putty’s performance.

Safety Precautions and Handling of HPMC For Wall Putty

Safety guidelines: Wear appropriate personal protective equipment (PPE) such as gloves, goggles, and masks when handling HPMC. This protects against potential skin irritation or respiratory issues.

Storage and disposal practices: Store HPMC in a cool, dry place away from direct sunlight and moisture. Follow the manufacturer’s instructions for proper storage conditions. Dispose of unused or expired HPMC according to local regulations to minimize environmental impact.

Handling considerations: Avoid inhaling or ingesting HPMC. In case of contact with eyes or skin, rinse thoroughly with water. If irritation persists, seek medical attention. Handle HPMC with care to prevent spills or accidents.

FAQ

Q: What is HPMC used for in construction?

A: HPMC could be used as a thickener, binder, and water retention agent in cement-based mortars, grouts, and plasters. It also acts as a lubricant during the extrusion of gypsum-based materials.

Q: What is HPMC for gypsum plaster?

A: HPMC is the perfect additive to increase the tensile strength of your gypsum plaster and other building materials. It is an adhesion agent that tremendously improves flexural strength and bonding strength. Gypsum plaster is also called POP.

Q: What is the safety of HPMC?

A: HPMC is generally recognized as safe and non-toxic in terms of its interaction with the human body. When used as a food additive, HPMC is inert in the digestive system and is not digested or absorbed by the gut.

Q: How do you prepare HPMC?

A: HPMC/PC blend films were prepared by the film casting technique. Briefly, at a ratio of HPMC : PC at 0.95 : 0.5 (HPMC95/PC5), HPMC solution was prepared by dispersing HPMC powder (0.95 g) in 70 mL of deionized water and constantly stirred using a magnetic stirrer at room temperature until a clear solution was obtained.

Q: How do you test for HPMC?

A: These test methods cover the testing of hydroxypropyl methylcellulose. The test methods are as follows: moisture; ash; chlorides; alkalinity; iron; heavy metals; methoxyl content; hydroxyproproxyl content; viscosity; pH; solids; and density.

Q: What are the different grades of HPMC?

A: The most commonly used grades of LV HPMC are E3 LV, E5 LV, E6 LV, E15 LV, E50 LV, and K100 LV. Besides grade, viscosity of HPMC dispersions also depends on vehicle composition and presence of additives.
