Discussion Overview

The discussion focuses on finding a suitable adhesive that can bond metal to latex or similar rubber-like materials. Participants explore various types of adhesives, their properties, and availability, considering factors such as cost, weight, and application methods.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks guidance on a lightweight, inexpensive adhesive that can bond metal to latex, emphasizing the importance of surface tension and availability.
  • Another participant suggests cyanoacrylate (Super Glue) as a potential option.
  • A different participant proposes using a two-part epoxy resin, mentioning personal experience with products like Bondo or PC-7/PC-11.
  • Another reply supports the two-part epoxy idea and introduces the concept of using a UV-catalyzed polymer resin for transparent layers, suggesting a photo-catalyzation process as an alternative to epoxies.
  • One participant raises the importance of flexibility in the adhesive and notes that larger surface areas may require less adhesion strength. They mention Liquid Nails and JB Weld as alternatives, depending on the need for flexibility and strength.

Areas of Agreement / Disagreement

Participants present multiple competing views on the types of adhesives suitable for the task, with no consensus on a single best option. The discussion remains unresolved regarding the ideal adhesive choice.

Contextual Notes

Participants do not clarify the specific requirements for flexibility or the exact conditions under which the adhesive will be used, leaving some assumptions unaddressed.

Hello,

I have next to no materials specific knowledge, so I was hoping someone here could guide me in the right direction.

I'm looking for a spreadable adhesive that has the following properties listed by priority:
1. Can adhere metal to latex or other rubber-like materials.
2. Inexpensive
3. Is very light when dried.
4. Good surface tension when uncured/dried
5. Readily available at a store or easy to purchase in small quantities online.


Strength (holding force?) is not that important, if that is a factor.

you sound like a chemical engineer to me, could you please give me reasons for studying chemical engineering other than the passion for chemistry, physics and maths?? thanksssss

Actually, I implied the opposite when I expressed my lack of materials knowledge.
 
Cyanoacrylate?

aka Super Glue.
 
2 part expoxy resin - not sure about the chemical bonds etc but I have used it for anumber of my projects
 
yep a two part epoxy like Bondo or PC-7 or PC-11 may work. you canget those at any hardware store

If it needs to be a fine even layer of adhesive you can use a cheap 2 part automotive paint and spray it on with an HVLP gun between your layers

ever hear of A UV-catalyzed polymer resin? if one of the layers you are gluing together is transparent you could use something like a photo-catalyzation process rather than an epoxide type scenario
 
I did not see if you needed it to be flexible.
Another factor is surface area, the larger the area the less adhesion
you need for the same strength.
If you do not need flex, liquid nails will have something that should work.
If your part needs some strength, JB Weld. (I repaired an outboard engine block with this)
