How to Choose Correct Cellulose Ethers for Putty Powders?
1. What are wall putty and its functions Cellulose ethers play a significant role in the formulation of wall putty, a versatile application of cellulose ethers. Wall putty , a finely powdered substance, serves to smoothen surfaces and establish a level base for subsequent paint coats by filling in minor cracks and pores on walls. Additionally, it aids in rectifying any unevenness present on the wall surface. In essence, it is an indispensable preparatory step before commencing painting. Ideally, a minimum of two coats of putty should be applied for optimal results. Characterized by high plasticity akin to clay, wall putty is augmented by the addition of cellulose ether. This additive enhances the functionality of wall putty, imparting improved strength and a superior finish to the surface. 2. Functions of cellulose ethers for putty Cellulose ether is a non-ionic semi-synthetic polymer derived from cellulose, available in two main types: water-soluble and solvent-soluble. It
