Winter Primer Freeze-Thaw Stability: HPMC + RDP
Winter construction puts primers to a severe test. In low temperatures, water freezes and expands, damaging the internal structure. Repeated freeze-thaw cycles cause the primer layer to peel, powder, and lose bond strength. Ordinary primers see sharp performance drops below zero, becoming a hidden quality risk for winter work. The synergy between HPMC and RDP
