| FAQ - Films and Preforms | |
| 1. Are films & preforms thermoset or thermoplastic? | |
| Most films & preforms are thermoset adhesives. Once cured, they are irreversible and will not reflow. Curing is initiated by heat. This is unlike thermoplastics which have the capability of reflowing multiple times. | |
| 2. What are the available formats for films & preforms? | |
| Films & preforms are available in sheets, preforms, or roll format. They can be supplied with or without the reinforcement of non-woven mesh. | |
| 3. How do films and preforms differ from liquids? | |
| Film and preform products are B-Staged adhesives. They are partially cured to a uniform thickness to fit your product’s geometry. They are applied to one surface and then heated to tack to the substrate. There is no mixing or dispensing. | |
