51-301 is a syntactic expanding epoxy film adhesive designed for core splicing applications, with a cure temperature range of 250-300¬8F (121-149¬8C). It features an expansion ratio of 2:1 to 3:1, making it suitable for strengthening splice areas where core joints meet, as well as for inserts and edge member attachments. The adhesive does not slump during curing, adheres to ASTM E-990 standards, and provides uniform expansion and cell size for enhanced strength. This product is resistant to humidity and chemicals, exhibits low exotherm, and can be co-cured with most 250¬8F (121¬8C) epoxy systems. It is available in standard film weights from 0.25-0.5 psf (0.05-0.10,Äù thick) and comes in sheets measuring 24,Äùx36,Äù, with other sizes available upon request. The recommended processing conditions include a cure cycle at 25 psi (172.5 kPa) and a ramp rate of 4-8¬8F/min (2.2-4.4¬8C/min) to 250¬8F (121¬8C), followed by a hold time of 60-90 minutes. The adhesive has a shelf life of 6 months at 40¬8F (4¬8C) and 12 months at 0¬8F (-18¬8C), with a 30-day out life at 70¬8F (21¬8C). Mechanical testing shows a tube shear strength of 930 psi (6.4 MPa) at room temperature and 980 psi (6.7 MPa) after a 3-day water boil, indicating strong performance in various conditions.
