SL 3000 High Temp Unfilled Laminating System

Description:

SL-3000 offers the most outstanding performance of any high-temperature laminating system available. The extremely high service temperature (425 F/220C) makes SL-3000 very well suited to high performance autoclave curing. SL-3000 will gel at room temperature, however, an elevated post cure is required to achieve ultimate physical properties.
