For Inorganic Acid Resistance
Concrete, because of its alkaline nature, is particularly susceptible to attack by inorganic acids. Whenever acid attack or mechanical damage creates the need for rebuilding as well as protection, this can now be achieved in one step using Belzona® 4181. In addition Belzona® 4181 is the ideal choice whenever there is a risk of impact damage or abrasion.
This totally novel trowelable material when exposed to inorganic acids, has the unique ability to form a protective surface barrier layer which further enhances its acid resistance. This is achieved using a complex acid catalysable hybrid resin system which also incorporates carefully selected close packing acid resistant fillers.
For Heat Resistance
Another feature of Belzona® 4181 is its exceptional heat resistance. When exposed to heat, the product's sophisticated chemistry forms a densely crosslinked polymer matrix which maintains its strength at elevated temperatures. By post-curing prior to service, therefore, Belzona® 4181 can withstand service temperatures in excess of those normally undertaken by more conventional polymer-based concrete repair materials.
Wherever resistance to heat or inorganic acids is important Belzona® 4181 is the concrete repair material of choice.
