How to make sure molded silicone rubber adheres to the ABS mold?

For one of my experiments I need to coat a 3D printed ABS part with a thin layer of silicon rubber:

Basically I want to make sure the molded silicon will adhere to one mold (the negative side in the picture above) but not the other. I'm using [V-SURE SILICONE NL Standaard from VOSSCHEMIE BENELUX](https://www.vosschemie-benelux.com/nl/product/silicone-rubber-sicovoss-v-sure-silicone-nl-standaard-a-b-0-5-kg) :

To ensure the positive side will be realised after rubberisation I use [the realise agent V-SURE TRENNSPRAY 400 GR from the same company](https://www.vosschemie-benelux.com/nl/product/hulpstoffen-loswas-v-sure-trennspray-400-gr):

I was wondering if there is anything similar for adhesion. Something like a spray glue or something I can smear with a brush. Thanks for your help in advance.


P.S.


1. I have absolutely no idea what are the products I'm using. I just bought them in a local shop for sculpting. I tried translating the website or googling the names with no good results. It would be also a great help if you could help me know what is the official/scientific names of the mentioned products.
2. I'm not able to find the right tags for this post. I would appreciate if the moderators could guide me with that.
3. I have also posted this question on Reddit ([molding](https://www.reddit.com/r/molding/comments/7mlzkv/how_to_make_sure_molded_silicone_rubber_adheres/?st=jbqe880f&sh=af77aac2), [modelmakers](https://www.reddit.com/r/modelmakers/comments/7mlwc1/how_to_make_sure_molded_silicone_rubber_adheres/?st=jbqe895e&sh=9b3b2dd2) and [ResinCasting](https://www.reddit.com/r/ResinCasting/comments/7mlv0g/how_to_make_sure_molded_silicone_rubber_adheres/?st=jbqe8a4f&sh=e51c9d20))
4. Maybe there are other moldable ruberry materials which have a better adherence to ABS? Any other type of flexible, wear resistance and strong rubber will do. For example I have seen lots of tinkers all over the internet using Caulk mixed with some moist absorbent powder (e.g. cornstarch) and oil, or soaked in water+soap.
5. Surprisingly the silicon sticks firmly to the glass beaker. I can't even remove it with a cutter!
