Guar Gum Modified Hydroxyethyl Cellulose GM-HEC HEC-35/HEC-40

Product Description of Guar Gum Modified Hydroxyethyl Cellulose

Guar Gum Modified Hydroxyethyl Cellulose (abbreviated as GM-HEC) is a high-performance modified cellulose ether additive specifically developed for water-based coating systems. Utilizing a graft copolymerization modification process of natural guar gum and hydroxyethyl cellulose, it integrates the core advantages of both, breaking through the performance limitations of traditional single thickeners. It provides a comprehensive solution for water-based coatings, including thickening, rheology control, water retention stability, and application optimization. Combining environmental attributes with excellent compatibility, it is widely used in various water-based architectural, industrial, and special coating applications

Key Properties of Guar Gum Modified Hydroxyethyl Cellulose

◆ Synergistic Thickening: Combines the rigid chain of cellulose ethers with the flexible chain of guar gum, providing superior rheological properties.
◆ High Water Retention: Significantly reduces the water evaporation rate during coating drying.
◆ Improved Leveling: Effectively reduces brush marks and roller marks, enhancing film surface smoothness.
◆ Anti-Spattering: Suitable for roller application, reducing paste spatter.
◆ Biostability: Enhanced resistance to microbial degradation after modification.
◆ Environmental Safety: Free from harmful substances such as formaldehyde and APEO, suitable for various indoor and outdoor environmentally friendly coating projects.

5 FAQs of Guar Gum Modified Hydroxyethyl Cellulose

Q1: What is the main advantage of GM-HEC compared to regular HEC?
A: It gives better overall performance. It combines the thickness of HEC with the smooth flow of guar gum, resulting in better leveling (fewer brush marks) and less spattering than regular HEC.
Q2: What is the difference between HEC-35 and HEC-40?
A: The main difference is viscosity. HEC-35 has a medium viscosity (22,000-30,000 mPa·s), while HEC-40 has a higher viscosity (28,000-40,000 mPa·s). Choose based on how thick you need your final product to be.
Q3: How should I add GM-HEC to my product?
A: Add the powder slowly to water with strong agitation. The typical dosage is 0.5% to 1.0% based on the water weight. Adding it during the grinding/dispersion phase helps prevent lumps.
Q4: Is GM-HEC compatible with other ingredients?
A: Yes. As a non-ionic thickener, it is generally compatible with most common ingredients in coatings and personal care products. However, testing in your specific formula is always recommended.
Q5: What does “enhanced biostability” mean?
A: It means the product is more resistant to degradation by microbes, which helps your final product last longer in storage. The powder itself has a 12-month shelf life when stored in a cool, dry place.
