SBR (Styrene-butadiene-rubber) is widely used for sealing profiles, edge protection, rubber gaskets and the like.
I am looking for a substitute that can be automatically applied to metal surfaces by “Form-in-place” technology using a six-axis robot and suitable dispensing system.
The substitute should be two-component or heat activated and fast curing to shore hardness of 70 to 80 and strong adhesion to the mounting surface
Hi Eugene
Thank you for your answer. That’s what I suggested too, it’s just that the current manufacturing process uses SBR-strips pressed into machined grooves of castings and for technical purpose and cost restraint we try not to change the basic chemistry.
The product is used in a very challenging and competitive environment.
Mr. Starke
It is not clear to me what you try to seal. I suspect you are not interested in welding, adhesives or conventional elastomer seals. For FIP you propably need a sealant, so my answer will be based on this: Acrylic's, Neoprene, Butyl, Polybutene, Silicone, Polyurethane and Polysulfide
I am sure you can limit the list for your requirements. A good reference that I recommend is: "Handbook of adhesives and sealants" by Edward M. Petrie
TABLE 14.5 Comparison of Various Sealants by Performance Properties (page 527)
An epoxy type rubber might work well, as their adhesion is great to all surfaces and they tend to be more heat stable than polyurethanes.
