I like how flexible it is. I need to make a Batman jumpsuit for my posable figure. Liquid latex makes lots of trapped bubbles and destroys my creation
Nice video, but can it be more stiff?
It seems really jelly in this video.
I need something like that, but I am makeing car rear wing, witch is originally made out of somekind of (foam)rubber. I want it to get same result, but they are not so jelly, but soft enought to squeeze between finger etc.
Before I get one, I would like to know it it traps bubbles like a lot of
This is fairly low viscosity but its inevitable that you'll trap some air bubbles, If you are careful with how you mix and pour you should be able to keep to a minimum.
What pigments should I mix for gray? I looked at the website and u only got black and white
the ptflex 20 is a beige / off white colour so you whatever pigment / dye you add you will have that come into play, adding small quantities of black polycolor dye will give a grey, or you could mix the black and white polycolors to have a grey to start. Alternatively we have the LR PTH pigments which we have a grey available.
Can I mix acrylic paint in the mixture and brush it to my posable figure? Can it be detached or separate from my figure once cured?
Not to say you couldn't but you it might not work so well and you are likely to have a few curing issues, we have a range of pigments that are proven to work with with the ptflex range.
@@MBFibreglass ok thank u. I’m guessing this will be delivered within Uk. I hope it would not be runny if I brush it on a 1:6 tb league posable figure and not sticking to the silicone. I am currently using liquid latex which they recommended a thickener but it’s making lots of bubbles. It’s ended horribly. I have wasted so much money on this project. It also destroyed the figure. It melted the silicone that the figure is made of because I accidentally trapped thick latex inside.
@@MrColanzar2007 yes, we are UK based. the ptflex 20 is quite low viscosity (generally not as thin as latex but it will be runny). We have tested this in varying rtv moulding rubbers without it sticking but you would need to test it to ensure it suits your requirements overall.
Great tutorial. Do you need a mask (with filters I mean) to manipulate this PT FLEX ?
thanks !
Hi, There are so many variables involved room size, ventilation facilities, size of castings being made etc. The Manufacture advises the following : 'If needed, an approved respirator with organic vapour cartridges may be used. Respirator selection and use should be based on contaminant type, form and concentration. Follow applicable regulations and good Industrial Hygiene practice'
Hi thank you for your tutorial. I'm curious to know what your flex mould is made of and is sheet thickness consistent throughout?
Lastly does it require a level table to make the flex mould maintain thickness?
Hi, the silicone was the polycraft S30 - link in video description, The base of the mould was approx 8-10mm thick at the base, (the mould walls are around 20mm thick due to the step in the mould) When creating the mould initially it was done so on a level surface so the mould itself was was able to self level and maintain an even thickness.
@@MBFibreglass thank kindly 🙏
Nice tutorial. This material is cold or hot when poured? Thanks
Hi, this is a cold pour (Room temperature cure)
Hi, can you please have a look at this polyurethane gel and see which one it is and if you have it?
Please copy and paste it on RUclips: Discover how a hair system is made at LaVivid
From the second 30. He applies a polyurethane translucent gel over a mold (head base), make it dry and then it is flexible like a kind of skin, and I guess it should be non-toxic? because it has to be in touch with your scalp. I'll appreciate if you can help.
assuming can this be used to make molds like pinkysil ?
the ptflex 20 could be used to make a mould but its primarily / best suited for casting parts etc
Nice! Could you suggest any urethane rubber model that has similar flexibility as this but is translucent?
The closest in spec would be our Duroflex 30, its a light amber translucent PU elastomer
@@MBFibreglass Thank you!
@@MBFibreglass Just another question.. Is the any clear matte paint which will bond well over urethane?
