HPMC For White Cement Based Wall Putty

Hydroxypropyl methyl cellulose (HPMC) is a cellulose ether that is commonly used as an additive in white cement based wall putty. It has a number of properties that make it well-suited for this application, including:

  • Water retention: HPMC can help to increase the water retention of wall putty, which can help to prevent it from drying out too quickly. This is important because wall putty needs to be wet in order to be applied and worked with properly.
  • Plasticity: HPMC can help to improve the plasticity of wall putty, which makes it easier to spread and work with. This is important because it allows for a smoother and more even finish.
  • Adhesion: HPMC can help to improve the adhesion of wall putty to the underlying surface. This is important because it helps to ensure that the putty will not crack or peel over time.
  • Slip resistance: HPMC can help to increase the slip resistance of wall putty. This is important because it helps to prevent the putty from slipping off of the wall during application.

In addition to these properties, HPMC is also non-toxic and biodegradable, making it a safe and environmentally friendly additive for wall putty.

The amount of HPMC that is added to white cement based wall putty will vary depending on the specific product and the desired properties. However, a typical amount is 0.5% to 1% by weight.

Here are some of the benefits of using HPMC in white cement based wall putty:

  • It can help to prevent the putty from drying out too quickly.
  • It can improve the plasticity of the putty, making it easier to spread and work with.
  • It can improve the adhesion of the putty to the underlying surface.
  • It can increase the slip resistance of the putty.
  • It is non-toxic and biodegradable.
