HPMC For Joint Filler

Hydroxypropyl Methyl Cellulose HPMC

Hydroxypropyl methylcellulose (HPMC) CAS9004-65-3 is a non-ionic cellulose prepared from natural polymer materials through a series of chemical processing. It contains methylcellulose (MC) with almost all properties and is your first choice for the production of high-quality building materials additives. In order to meet the needs of environmental protection, our HPMC powders have high water retention, dispersibility, good fineness, good workability, and easy-to-use dissolution characteristics.

HPMC hydroxypropyl methyl cellulose is suitable for building dry powder mortar, internal and external wall putty powder (paste), adhesives, caulking agents, joint cover, interface agents, coatings, and self-leveling agents for new building materials additives.

Joint Filler HPMC PROPERTIES:

* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.

* Charring temperature: 280-300℃.

* Bulk density: 0.25-0.70 g/cm³ (Usually around 0.5 g/cm³ )

* Real specific gravity: 1.26-1.31.

* Browning temperature: 190-200℃.

* Surface tension: (2% water solution) 42-56dyn.cm.

* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.

Performance in joint cover

In joint cover, the addition amount of HPMC is very low, only 0.1%-1%, but it plays an irreplaceable role and can significantly improve the water retention, fluidity and lubricity of building materials. Building materials added with HPMC are easier to mix and use, improve the work efficiency of construction workers, extend the open time, improve the bonding strength, and form a smooth and delicate surface coating.

Features of HPMC for joint filler

• Crack-Resistant Strength: Enhance mortar and caulking agents with HPMC for superior anti-cracking strength, ensuring robust and durable constructions.

• Structural Integrity: Optimize mortar air content to reduce the risk of cracks, providing a solid and resilient foundation for your projects.

• Extended Workability: Improve construction efficiency with Haoshuo's HPMC for joint filler, offering extended working time and enhanced water retention for consistent results.

• Adhesive Reliability: Integrate HPMC cellulose ether for improved joint sealant adhesion, high abrasion resistance, and minimal shrinkage, fortifying against water damage.

Joint filler application guide

• Increase the bonding strength of wet mortar

• Good water retention can make sure the cement and other additives fully hydrated which can increase the woking time and reduce the risk of cracking.
