Iran's construction sector faces severe challenges due to extreme thermal expansion and contraction cycles. In regions like Tehran and Isfahan, the rapid evaporation of water from mortars necessitates the use of high-quality hydroxymethyl propyl cellulose to ensure adequate water retention and prevent shrinkage cracks.
Furthermore, the prevalence of saline soils in southern coastal areas demands chemical additives that can mitigate the corrosive effects of sulfates. The integration of polycarboxylate admixture has become essential for creating high-strength, low-permeability concrete that resists chemical ingress.
Economically, the Iranian market is shifting toward prefabricated components and dry-mix mortars. This transition has spiked the demand for redispersible latex powder to improve bond strength and flexibility in tile adhesives and external thermal insulation systems (ETICS).
