Best Practices for Henkel F245
These toughened acrylic adhesives will tolerate a degree of surface contamination but for ultimate performance light abrasion (i.e. Emery Cloth or Shot Blasting) is recommended. An in-process quality check of the surface preparation process can be provided by using Bondmaster SIP to ensure consistent results and to further enhance the environmental durability of the joint.
Apply the Initiator sparingly to one surface. (Excess does not give a faster cure but it may reduce the final bond strength). If bonding porous surfaces then apply the Initiator to the porous surface.
Apply the adhesive to the second surface as a bead. Ensure that sufficient adhesive is applied to completely fill the joint and that no air is trapped in the bond line.
When bonding large areas F245 may be combed out to achieve uniform coverage. The maximum on-part life of F245 is 30 minutes and assembly must occur within this time if ultimate performance is to be achieved.
Apply light clamping pressure whilst the adhesive develops handling strength.
