Aluminium Trihydrate (ATH)

ATH is a versatile inorganic additive widely used in construction and cementitious systems as a flame retardant, filler, and rheology modifier. In concrete admixture and drymix applications, ATH can contribute to improved fire resistance, enhanced dimensional stability, and controlled setting behaviour while also assisting with formulation consistency and workability. Commonly incorporated into repair mortars, grouts, coatings, and specialty cement systems where thermal stability and filler performance are required.
