Photopolymer - Liquid that rapidly solidifies when exposed to UV light
77,00 kr
Used for:
Photopolymers are used in dentistry and in glues for industrial applications. The liquid in SLA 3D printers is also a photopolymer. You can buy a DIY repair kit with a pen that squirts out photopolymer and a small UV flashlight.
Details:
Photopolymerisation occurs when a photoinitiator in the liquid is split into reactive molecules by UV light. These molecules combine with monomers and oligomers (several connected monomers) to form the rigid polymer. Unlike regular glue, photopolymers do not dry out or cure when exposed to air. They will even polymerise under water.
Idea:
Use it to support a split fingernail while it heals.
The sample:
You can get an acrylic plate with a cured "F" - see the picture. We also have a starter set with liquid polymer and a UV flash light.
All samples come with a laminated information card.
QUESTIONS & ANSWERS
Ask a Question-
I would like to coat the tips of welding wire rods in various colours as a visual indicator of what material type it is - e.g Red, Blue, Green, ect. Does this product come in various colours that can be hardened under UV light.
The raw material is clear, but you can buy concentrated colours you can add or you can buy fully coloured resins which are used for SLA and DLP 3D printers. Check this product - https://formlabs.com/blog/introducing-color-kit/

Can the photopolymer be applied in a spray or have a solid dipped into them to coat them and then solidified with UV light?
Yes, this a widely used process called "UV Coating". You can read more about the different applications on Wikipedia - https://en.wikipedia.org/wiki/UV_coating

What is the tensile strength of this material?
The supplier lists the strength to 2000 Psi = 13.8 MPa. There many different photopolymer materials on the market. One of the big applications is for SLA 3D printing, so I suggest you take a look at the materials available for SLA.
