GSP 1329 and GSP 1329-1 are two-component epoxy systems used for potting and adhesive applications. The cured products exhibit good impact strength and very good general adhesion. These systems have about a 2-hour work/pot life allowing for longer fixture times. The systems can be utilized with variable mix ratios to tailor specific physical properties. The cured system develops very good adhesion on a wide variety of substrates. Mix ratios may vary between from 1A:1B up to 3A:1B by volume depending on the properties desired. Most common are 1A:1B and 2A:1B mix ratios. A 1A:1B mix ratio yields a cured system with more impact strength, flexibility and peel strength. A 2A:1B mix ratio may be used for better chemical & thermal resistance, hydrolytic stability, higher shear strength . Greater flexibility can be further achieved with a 3A:1B ratio.
