Structural? Rigid or flexible? Curing mechanism Advantages Disadvantages - Storage EPOXY 1C Yes Rigid Heat - Strength and durability - Cures at high temperature - Slow curing EPOXY 2C Yes Rigid Chemical reaction - Strength and durability - Mixture (voids) - Brittleness - Good strength at low temp - Limited temperature and UV POLYURETHANE Yes Flexible Moisture - Toughness resistance - Wetting ability - Low impact of surface ACRYLIC Yes Rigid Chemical reaction preparation - Mixture (voids) - Fast curing - Good sealing capability - Cannot be painted SILICONE No Flexible Moisture - Good humidity and UV - Low strength resistance - Cannot bond large areas ACRYLIC: No Rigid Substrate moisture - Fast curing - Brittle CYANOACRYLATE - Bad gap filling Absence of air and ACRYLIC: ANAEROBIC No Rigid presence of metallic - Little surface preparation - Thin bondlines ions - Fast assembly - Limited mechanical DOUBLE-SIDED TAPE No Flexible Pressure - Reversible joint resistance - Fast curing - Limited mechanical and HOTMELT No Flexible Solidification - Reversible joint thermal resistance
