TAL GOLDSTAR 2 is classified as a C1TF adhesive (cementitious tensile adhesion strength (C1), slip resistant (T), fast setting (F), adhesive). When mixed with TAL BOND as a total water replacement, or when TAL BOND POWDER is incorporated in the mix, TAL GOLDSTAR 2 is classified as a C2TFS1 adhesive (improved cementitious tensile adhesion strength (C2), slip resistant (T), fast setting (F), deformable (S1), adhesive) When mixed with TAL KEYCOAT or TAL SCREEDBINDER as a total water replacement TAL GOLDSTAR 2 is classified as a C2TFS2 adhesive ( improved cementitious tensile adhesion strength (C2), slip resistant (T), fast setting (F), more deformable (S2), adhesive).
