Technical datasheet12 /06/2011 RESOLTECH 3350 Hardener 3358 Structural Epoxy adhesive Adhesion promoter for secondary laminations Rubber toughened epoxy High shear and peeling resistances Excellent applicability (grease-like consistency ) Non sagging vertical applications > to 5mm & 10 mm horizontal All weather applicability even in high humidity conditions. The RESOLTECH 3350 structural adhesive is a high performance adhesive offering a high tenacity and toughness. Its good elongation ratio enables to bond most materials, even if they have a large CTE difference. Resoltech 3350´s rheology is close to a universal grease, making the mixing and application very easy with a spatula or even with a brush. The vertical sagging limit of 5mm on vertical applications & 10mm on hortizontal applications will enable to bond bulkheads with 10 mm diameter fillet joints Particularly resistant to the propagation of micro-cracking, this system is well adapted to the bonding subject to important cycles of fatigue. The areas of application of the 3350 are very varied: structural composite bonding, adhesion promoter on secondary lamination specially on pre-pregs...etc. Page 1/5 RESOLTECH RESOLVING YOUR ENGINERING CHALLENGES www.resoltech.com

Resin 3350 Hardener 3358 Secondary lamination structural adhesive MIXING RATIO By weight Resin 3350 Hardener 3358 100 42 Le rapport de dosage doit être respecté sans excès ni défaut. Le mélange doit être intime et homogène avant l’utilisation. APPLICATION The surface should be clean, dust-free and degreased. Prepare all surfaces by abrading with medium grit paper or other suitable abrasive, remove dust then wipe with acetone, MEK or similar solvents Metals usually require a chemical pre-treatment to create the best bond (contact Technical Services). Ensure that polyester or vinylester...
