Precautions (please learn carefully earlier than use): 1: Resin glue curing velocity is said to volume size and temperature, the thicker the adhesive layer, the speedier the curing, the better the temperature, the speedier the curing.Therefore, the extra mixing, the shorter the operating time, the larger the scale of the seal will be, the slower the reverse. 2: Resin and curing agent reaction could be hot, the thicker the glue layer will produce extra heat, heat assembly has bubbles produced, so the matching glue to be used quickly, brush thin will solidify slowly. 3: A,B two groups needs to be strictly proportional weighing, B components too much or too little will influence the performance of the curing; A, B two ingredients mixed, should stir evenly, stirring choppy will trigger part of the curing, part of the non-curing condition. If you're a beginner, please use an electronic scale to simply confirm the ratio of A glue to B glue. 4: Glue within the curing process, curing agent will suck tide, when the air humidity is large, after curing the outside will have a layer of oily feeling, so the curing activity to maintain dry, do not solidify in the humidity of the environment, when the oil is produced, you might dry the surface, after which sandpaper grinding. 5: When the temperature is low, the A section will have crystallization phenomenon, corresponding to the production of granular rubber slag or completely frozen, when the use of a glue can be heated, the temperature may be open, after the opening can be utilized normally, does not impact the performance. 6: Use is careful not to contact the skin, contact with the skin sometimes there will be allergic phenomenon produced! Please wear disposable gloves through the DIY crafts making process.
