RDP Tg: The Key to Cement Mortar Flexibility
rittleness and cracking have long been major concerns in cement‑based mortars. Adding redispersible polymer powder (RDP) greatly improves flexibility, yet the actual performance can vary widely. The root cause is often the glass transition temperature (Tg) of the RDP. Tg is not just a technical number. It directly determines whether the polymer film stays soft
