Rock West Expanding Foam Adhesive is an expanding syntactic epoxy film adhesive (51-301) produced by Newport / Mitsubishi Chemical. This adhesive is specifically designed as a core splice material, for strengthening the splice area where core joints meet. It is also suitable for inserts and edge member attachments as well as filling available space where bladder molding is difficult.
Recommended processing conditions 51-301 is typically cured at 250°F to 300°F (121°C -149°C) depending on part size and complexity. Low, medium and high pressure molding techniques may be used depending on the desired level of expansion. Recommended cure cycle is 25 psi (172.5 kPa); 4-8°F/min (2.2-4.4°C/min) ramp to 250°F (121°C), hold for 60-90 minutes, cool to <140°F (60°C).
