Bicomponent liquid silicone rubber molds for casting
The GLS-50 is a liquid silicone rubber to be used for casting. Its high viscosity apparently manages to penetrate everywhere, and to reproduce every detail. And 'suitable for building molds well, ie monovalva, small objects also very detailed and with strong undercut as figurines, statues, carvings, candles etc.
Even with some devices can be realized clamshell mold or cavity, to reproduce objects of more complex structure or larger; request brochure Construction silicone rubber molds.
Before use, the GLS-50 should be added the 5% of catalyst "T-30", a colorless liquid. It 'always advisable to weigh your components by weight. Not having a precision scale for the determination of small amounts of catalyst, you may either use a syringe fitted to dose and volume: 1 cc. equals 1 gr. while the rubber, which constitutes the highest quantity must necessarily be weighed, also because it has a different specific weight, equal to 1.2.

Together the two components in a vessel at full aperture, is mixed with a spatula blade, narrow and elongated for about one minute, taking care to scrape off the wall and the bottom of the container, so as to obtain a homogeneous mixture throughout the mass . Mix slowly to avoid excess formation of air bubbles. Before casting is good to make the dough rest at least 10 minutes to allow venting.
This type of silicone rubber has a very long pot life (over 1 hour), and this allows the almost total sbollatura air incorporated.
La vulcanization is complete after approximately 18 hours at 20 ° C. If you want to accelerate the reaction it can be vulcanized to the dough in an environment at a temperature of 30 - 40 ° C, or near a heat source. A reaction too fast does not allow the complete escape of air bubbles.

Pour the silicone rubber directly above the model to be reproduced, previously placed inside a container.
Pour the silicone rubber slowly at intervals, by acting with a brush in correspondence with the protruding details and undercuts, to facilitate the escape of the air bubbles that tend to form at these points. Bridging the mold so as to coat the model abundantly.
To maintain the mold in efficiency and prolong battery life when it is used to obtain many consecutive copies, it is advisable to follow these expedients: ritemprarlo, every 20 printed by placing it in an oven for about one hour at 100 ° C in order to allow the evaporation of solvents or other substances absorbed by the rubber. Also you can squeeze the mold with silicone oil, so that the rubber riseccata use reabsorb the silicone which gradually lost.
When the job is not necessary to wash containers and smeared with rubber spatulas; after vulcanized breaks away from tools, leaving surfaces clean and free of debris.
