Frequently Asked Poly-forms Questions

What type of oven is recommended for processing MSI Poly-form adhesive preforms?
The consistency of the final bond or seal depends mainly upon three factors: (1) the consistency of the component being sealed, (2) the consistency of the adhesive preform, and (3) the consistency of heat transfer (i.e., oven). Factors 1 and 2 are close toleranced and should not be the cause of inconsistencies. Therefore, the oven system will require the closest attention. We recommend the use of a mechanical convection (forced air) oven. This type of oven allows for fastest recovery and the most consistent means of heat transfer. If a static air oven is used, MSI's recommended cure schedules should be doubled or increased according to the results of qualification tests. The oven should be calibrated at least one a year.

What other equipment can be used to process Poly-forms?
In addition to mechanical convection ovens, Poly-form flexible adhesives can also be activated with hot plates, tunnel ovens, heat lamps, and portable heat sources.

What are the storage requirements for Poly-forms?
Poly-form adhesive films should be stored in a cool, dry area. An air-conditioned office environment is best but not absolutely necessary. The preforms should be kept in closed containers when not in use.

Do Poly-forms require refrigeration?
We do not recommend refrigeration, as this will cause condensation and moisture contamination if improperly handled.

Are Poly-forms available as off-the-shelf items?
Most Poly-form adhesive preforms are selected or designed for specific components. Please contact MSI to discuss the details of your application. We will also conduct free evaluations of components for sealing with our Poly-forms.

Sample quantities of common preform configurations are available through this web site. Please call us or visit Free Sample Packs for details and ordering instructions.
