①All data above were tested under standardized condition.
②All data listed in the chart were for the generalized item in the series; please refer to the related data sheet for special items.
③Storage condition has a direct impact to the products’ shelf life, Please refer to the instruction for special items’ storing
1.Mix Part A and Part B by proper rate evenly, remove bubbles by vacuumize. Potting the product within application time, if the product is too big, advice to potting by times, then curing in 80℃/90min or 25℃/10hr
2.Part A will have sediment if stay for long time. Advice to stir Part A evenly before using. Seal the parts after using.
3.Stirring by one direction for avoiding the bubbles; the frame and bottom also need to be stirred evenly, or it will cause not cure situation.
4.Vacuumize again after potting for removing the bubbles, which can improve the general properties
5.Low temperature will slow the curing speed, advice to heat cure; if the potting thickness is over 2cm, the sealant can’t cure under 80℃ for avoiding the implosion.
6.The curing process is exothermic reaction, the amount of sealant will influence the application time. So the application time of 100g is just for reference.
