The adhesives furnished under this specification shall be products which are authorized by the qualifying activity for listing on the applicable qualified products list at the time of award of contract (se

25、e 4.3 and 6.3). adhesives on the applicable qualified products lists shall be dependent on periodic verification of continued compliance with the requirements of this specification (see 4.3.3). In addition, the retention of the qualification for 3.2 Materi al s. 3.2.1 Formulation. The adhesives shal

26、l be thermosetting. There shall be no restrictions on the chemical structure of the adhesives. 3.2.2 Curinq aqents. Curing agents shall be supplied for mixing with the adhesive or shall be incorporated into the adhesive. 3.2.3 Solvent. When a solvent is required for the adhesive, it shall be furnish

27、ed as part of the adhesive system by the manufacturer and its function shall be identified on the label. 3.2.4 Filler. A filler may be incorporated into the adhesive. Any such filler shall be considered as a part of the adhesive system and shall remain uniformly dispersed and suspended in the mixed

28、adhesive during its normal pot life. The filler shall be readily dispersible throughout the adhesive during its entire usable storage life. The filler shall be highly moisture and corrosion-resistant and shall withstand the maximun! temperatures stated for the adhesive. 3.2.5 Forms (see 1.2.3). 5 Pr
