Processing
Version 1 Scenario 1: Room-temperature bonding between silicone rubber substrates 1. Surface thoroughly cleaned prior to bonding 2. Apply adhesive evenly, coating thickness controlled under 5mm 3. Keep compressed for over 120 minutes; full curing completes in 24 hours at 25°C Scenario 2: Room-temperature bonding of silicone rubber and metal 1. Wipe bonding surfaces clean with anhydrous ethanol 2. Coat thin layer of CL-24S-4 primer once on treated surfaces 3. Cure primer naturally for 30 mins at room temp, or 5-15 mins at 90°C 4. Spread KN-300 glue after primer sets, press no less than 120 mins; fully cured in 24h at 25°C Scenario 3: Room-temperature bonding of silicone rubber and plastic 1. Purify bonding surfaces using or absolute ethanol 2. Apply a single thin coat of CL-24J activator on cleaned areas 3. Leave for 30 minutes to finish room-temperature curing
