Storage & Shelf life:
The shelf life of SO-4075 stored at 12℃- 23℃ is 12 months from the date of manufacture.
Cool storage at around 12℃ can extend the shelf life.
Long-term exposure above 23℃ will reduce the shelf life.
Prolonged exposure of activators, including cartridges that contain activators, above 35℃ quickly diminishes the reactivity of the product, and should be avoided. This product should never be frozen.
General Description
SpiderAdhesive SO-4075 is a two-part 10:1 non-sagging methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies, and with very good bond strength of SMC.
SpiderAdhesive SO-4075 is an excellent choice for composite bonding applications in the transportation, marine, wind energy, and engineering construction industries because of its high strength and durability. It generally requires minimal surface preparation.
SpiderAdhesive SO-4075 also provides superior toughness, even at low temperatures.
