A few tips/cautions in using Eotite p-102: 1) Keep the mixture ratio of 100:2 correctly, which is understandably not easy because the total amount of mixture is small 2) Mix throughly. This is very critical because the amount of hardner is very little. Mix at least ONE MINUTE! 3) When heated for curing, make sure the temperature around the glue is really that temperature. 4) This glue can be cured at room temperature in 24 hours. However, there is a critical temperature, about 22 deg.C, below which the glue does not cure or curing takes very long hours.
