MULTI-SEALS Poly-forms are flexible pre-shaped adhesive films designed for bonding diverse materials, including metals, plastics, and glass. The preformed copolymer prevents drips and dispensing inconsistencies typical of liquid adhesives. The flexibility and durability of Poly-form adhesive films facilitate manual and automated handling for increased production rates. Poly-Forms can be pre-shaped in multiform configurations to accommodate a broad range of sealing and bonding applications.
The temperature and time required to process Poly-forms depend upon component materials and mass, application requirements, and the location of the seal within the assembly. The charts below provides typical processing schedules. Please refer to material data sheets for complete processing instructions and alternate schedules.
Summaries of our flexible adhesives are listed below.
No-flow flexible adhesive system. Negligible vertical flow keeps the adhesive contained in precisely defined areas. Adding clamping pressure during cure improves adhesion.
225°F (107°C) for 60 minutes at 50 psi*
250°F (121°C) for 10 minutes at 50 psi*
* effective clamping pressure
See processing instructions on datasheet for additional recommended temperatures, times, and clamping pressures.
Store below 80°F (27°C). Protect from humidity, moisture, and contamination
Flowing flexible adhesive system. When heated, initial flow properties allow the adhesive to spread into narrow interfaces and around complex features. When the adhesive sets, any further flow is restricted.
260°F (125°C) for 90 minutes
300°F (150°C) for 45 minutes
350°F (175°C) for 20 minutes
390°F (200°C) for 15 minutes
See processing instructions on datasheet for additional recommended temperatures and times.
Store below 39°F (4°C). Protect from humidity, moisture, and contamination
