Product Description of Hydrophobically Modified Hydroxyethyl Cellulose HM50
HM50 is a non-ionic water-soluble associative polymer after chemical modification of cellulose. It is specially used to form high-quality color dots in water-based sand multi-color coatings. The recommended dosage is 0.3%-0.9%.
Packaging: 20kg/bag
Shelf life: 1 year
Main Performance of Hydrophobically Modified Hydroxyethyl Cellulose HM50
Excellent color dot appearance: presents a more textured appearance, reducing the fragility of color dots and the impact of color bleeding on the appearance;
Good thickening property: has better thickening performance than conventional cellulose due to hydrophobic association;
Good construction performance: has good anti-splashing, film-forming, water retention, and good storage stability;
Good dispersibility: will not agglomerate in acidic and neutral water, and is easily dispersed in organic solvents such as ethylene glycol;
Good compatibility: compatible with various synthetic polymers and emulsions;

HM50 Mildew Resistance Test
1. Dissolve into 1% aqueous solution and test the initial viscosity;
2. Add a certain amount of biological enzyme solution and test the viscosity after 24 hours;
3. Remaining viscosity percentage = viscosity after 24 hours/initial viscosity x 100%.

FAQs of HM50
1. What is Hydrophobically Modified Hydroxyethyl Cellulose (HMHEC)?
HMHEC is a type of cellulose ether that has been modified to include hydrophobic groups. This modification enhances its ability to thicken and stabilize water-based systems, making it useful in a variety of applications such as paints, coatings, adhesives, and building materials. The "HM" stands for "hydrophobically modified," and "50" typically refers to a specific grade or product line within the HMHEC family.
2. What are the main benefits of using HM50?
The main benefits of HM50 include:
Thickening: It effectively increases the viscosity of aqueous systems, which can improve the handling and application properties of products.
Stabilization: It helps to stabilize emulsions and suspensions, preventing settling or separation over time.
Enhanced Performance: It can improve the wetting, leveling, and anti-sagging properties of formulations.
Compatibility: It is compatible with a wide range of other additives and materials, making it a versatile ingredient in many formulations.
3. How does HM50 differ from other cellulose ethers?
HM50 differs from other cellulose ethers primarily due to its hydrophobic modifications. These modifications:
Increase Viscosity: Provide higher thickening efficiency, especially in low-shear conditions.
Improve Stability: Enhance the stability of formulations, particularly in high-temperature and high-humidity environments.
Reduce Water Sensitivity: Make the polymer less sensitive to water, which can be beneficial in applications where water resistance is important.
4. What are the typical applications of HM50?
HM50 is commonly used in:
Paints and Coatings: To improve flow, leveling, and sag resistance.
Construction Chemicals: In mortars, plasters, and tile adhesives to enhance workability and open time.
Adhesives and Sealants: To improve cohesion and adhesion properties.
Personal Care Products: As a thickener and stabilizer in creams, lotions, and gels.
Textile and Paper Coatings: To improve the quality and performance of coatings.
5. How should HM50 be handled and stored?
To ensure optimal performance and shelf life, HM50 should be:
Stored in a Cool, Dry Place: Avoid exposure to high temperatures and humidity, which can degrade the polymer.
Kept Sealed: Store in airtight containers to prevent moisture absorption.
Handled with Care: Use appropriate personal protective equipment (PPE) when handling to avoid skin or eye contact.
Disposed of Properly: Follow local regulations for the disposal of unused or waste material.
