ACRONAL® S 430 P is mainly used to modify hydraulic binders. Because it has low glass transition temperature and high elasticity, it can be used to reduce the elastic modulus of mortars and increase their elongation at break, their abrasion resistance and their adhesion. It provides a large increase in flexibility, even at temperatures below 0 ºC. The special additive system employed in ACRONAL S 430 P ensures excellent workability, a long shelf life and no cracking when the mortar sets. This product is completely free of cellulose derivatives and inorganic extenders.

ACRONAL S 430 P can be added to dry powders that are employed as construction adhesives and in cementitious waterproofing systems. Its high binding strength and rapid redispersibility also allow it to be used in formulations in which the polymer acts as the main binder or the sole binder.

Examples of cementitious waterproofing systems include flexible waterproofing slurries for balconies, patios and cellars. Up until now, most of the products on the market have been two-component systems which were often based on ACRONAL S 430 P. With ACRONAL S 430 P, it is now possible to formulate single-component powder products with exceptionally high flexibility and good adhesion on difficult substrates.

ACRONAL S 430 P can be used in highly flexible ceramic tile adhesives which do not fail even if they are exposed to large fluctuations in temperature outdoors Single-component products formulated with ACRONAL S 430 P also perform very well on substrates that are subject to movement such as wooden floors, because these demand very flexible tile adhesives. ACRONAL S 430 P can also be used to improve the properties of adhesive sealants.
