Usage Instructions
Mixing weight ratio of WSD-302AB: A:B = 10:10. Please finish usage within 4 hours after mixing.
Weigh A and B components according to the ratio and stir uniformly.
Put mixed adhesive into vacuum equipment for defoaming, then pour it into sealing parts or coat it on bonding joints.
Heat at 200℃ for 10–15 seconds; the adhesive will form silicone elastomer after complete curing.
