First, the chemical name : Rapid prototyping of plastic ,
Chemical Product name : AB Water or PU glue
Second, the use
(1) Measurement. A liquid, B The weight of the whole liquid mixing ratio : 1: 1. Paper cups or other containers to weigh the amount of A liquid , Then weigh the same weight with the other cups or other containers B liquid . Please weighed accurately ,A Liquid and B The amount of liquid consistency . If the weight deviation is too large , It may make the surface of the cured product can not be completely cured / Or the color of the cured material deviations occur .
(2) mixing would be the main method of accurately weighed B Pour liquid A Solution , Then stir with a metal spatula or glass rod . If uneven mixing , It may make the surface of the cured product can not be completely cured / Or the color of the cured material deviations occur .

(4) after the release smoked vacuum , The good irrigation AB Water silicone mold is placed flat bench , Wait 10~20 minute , You can release , Since the curing reaction heat causes the curing temperature thereof rises , Please note that to avoid scalding accident , If premature release , High temperature curing due chilled , Deformation may occur .
(1) water vapor to A / B Two liquid quality will be adversely affected , We should absolutely avoid mixing water .
(2) B solution will react with water to produce a white turbid or curing , It should have become opaque , Or have been cured , Please do not use .
