Raw Material Cellulose Ether HPMC for Wall Putty

Cellulose ether HPMC (hydroxypropyl methylcellulose) is a versatile raw material that is widely used in the construction industry, including for wall putty. It is a non-ionic, water-soluble cellulose derivative that is known for its excellent thickening, water-retention, and adhesive properties. These properties make it an ideal additive for wall putty, as it can help to improve the workability, adhesion, and overall performance of the putty.

Benefits of using cellulose ether HPMC for wall putty:

  • Improves workability: Cellulose ether HPMC helps to make wall putty easier to mix and apply, reducing the amount of effort required. This is because it acts as a lubricant, reducing friction between the putty particles.

  • Enhances adhesion: Cellulose ether HPMC helps to improve the adhesion of wall putty to walls and other surfaces. This is because it forms a strong adhesive bond with both the putty and the substrate.

  • Increases water retention: Cellulose ether HPMC helps to prevent wall putty from drying out too quickly, which can lead to cracking and other problems. This is because it absorbs water and forms a gel, which helps to retain moisture in the putty.

  • Improves smoothness and finish: Cellulose ether HPMC helps to create a smoother and more finished appearance for wall putty. This is because it helps to fill in voids and gaps in the putty, and it also helps to prevent sags and drips.

Typical dosage of cellulose ether HPMC for wall putty:

The typical dosage of cellulose ether HPMC for wall putty is 0.1% to 1% by weight of the putty. The exact amount will depend on the specific properties of the putty and the desired performance characteristics.

How to use cellulose ether HPMC for wall putty:

Cellulose ether HPMC can be added to wall putty in either powder or slurry form. If adding it in powder form, it should be dispersed evenly throughout the putty before mixing with water. If adding it in slurry form, it should be premixed with water to form a smooth paste before adding it to the putty.
