FAQ
Wall putty manufacturers commonly use cellulose ethers such as HPMC, HEMC, and RDP to improve water retention, workability, adhesion, and application performance. The suitable additive depends on the putty system, raw materials, and required finishing properties.
Cellulose ether is non-toxic, biodegradable, and widely regarded as safe for use in construction materials, aligning with international environmental and safety standards.
Yes. LANDU provides samples and technical information for customers who want to evaluate cellulose ether performance in their own wall putty formulations. Testing with your existing raw materials is recommended to select the most suitable grade.
