Adding hydroxypropyl methylcellulose to make putty powder, its viscosity is not easy to be too large, too large will cause poor workability, so how much viscosity does hydroxypropyl methylcellulose for putty powder need?

Please visit our website for more information on this topic.

It is best to add hydroxypropyl methylcellulose to the putty powder with a viscosity of 10 or 75,000, which can improve the workability of the putty powder, and its water retention is also very good. If it is used for mortar, it needs a slightly higher viscosity, such as 150,000 or 200,000 viscosity. Generally, hydroxypropyl methylcellulose has better water retention with higher viscosity.

What is the use of adding hydroxypropyl methylcellulose to putty powder? What is the main role?

HPMC is used in putty powder to thicken, retain water and improve construction performance. Thickening: cellulose can thicken to suspend, keep the solution uniform and consistent, and resist sagging. Water retention: make the putty powder dry slowly, and assist the ash calcium to react under the action of water. Construction: Cellulose has a lubricating effect, which can make the putty powder have good construction.

Hydroxypropyl methylcellulose does not participate in any chemical reaction in putty, it only plays an auxiliary role, and it is colorless and non-toxic. It is the most commonly used additive in modern buildings and is widely used in putty mortar

Three Considerations for Wholesale HPMC Powder

When purchasing Hydroxypropyl Methylcellulose (HPMC) powder wholesale, there are several important considerations to keep in mind to ensure that you select the right product for your specific needs. Here are three key considerations:

1. Quality and Purity:
   • Ensure that the HPMC powder meets high-quality standards and is of consistent purity. Look for suppliers who adhere to stringent quality control measures and have certifications or accreditations to support their claims.
   • Check for the absence of contaminants, such as heavy metals, residual solvents, or microbial impurities, which could affect the performance or safety of the product.
   • Request product specifications, certificates of analysis (COA), and other relevant documentation from the supplier to verify the quality and purity of the HPMC powder.
2. Technical Specifications:
   • Consider the technical specifications of the HPMC powder, including viscosity grade, particle size distribution, moisture content, and other relevant properties.
   • Choose a viscosity grade that is suitable for your intended application. Different viscosity grades of HPMC powder offer varying levels of thickening, water retention, and other rheological properties.
   • Evaluate the particle size distribution to ensure uniformity and consistency in the performance of the HPMC powder. Smaller particle sizes typically provide better dispersion and mixing characteristics.
3. Supply Chain and Logistics:
   • Assess the reliability and stability of the supplier&#;s supply chain to ensure consistent availability of the HPMC powder.
   • Consider factors such as lead times, shipping options, packaging, and storage requirements when selecting a supplier.
   • Evaluate the supplier&#;s track record in terms of on-time delivery, customer support, and responsiveness to inquiries or concerns.
   • Seek suppliers who offer flexible ordering options, such as customizable packaging sizes or bulk discounts, to accommodate your specific requirements and budget constraints.

By carefully considering these factors, you can make an informed decision when purchasing HPMC powder wholesale and ensure that you select a high-quality product that meets your technical specifications and supply chain needs.
