Loctite F241 is a 2 part -'no-mix' adhesive which cures rapidly at room temperature. Its exceptionalresistance to peel, fatigue and impact loads on a wide variety of surfaces, combined with excellent environmental durability and chemical resistance, make it ideal for applications demanding structural integrity. This outstanding performance can allow the adhesive to be used in place of rivets and/or weldingDirections for Use: 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 Loctite SIP to ensure consistant 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. Apply light clamping pressure whilst the adhesive develops handling strength. F241 must be applied as a bead - do not spread or comb out the adhesive as this will result in reduced bond strength. The maximum on-part life of F241 is 5 minutes and assembly must occur within this time if ultimate performance is to be achievedthereby providing reduced assembly times, lighter structures and an improved aesthetic.
