Assembling Speakers with Loctite ® AdhesivesGasket to SurroundAs with other bondlines, if drivers are subjected totesting immediately after assembly, cyanoacrylates offerexcellent cure speed, ensuring highly stable and repeatableend-of-line measurements. The use of acceleratorson gasket bonds can allow the drivers to be packagedimmediately after QA testing, without gasket "squirming"problems.Since this is a cosmetically sensitive bondline,consideration should be given to automated adhesiveplacement, which may also minimize the quantity ofadhesive used.Recommended products for the Gasket to Surround Assembly:Loctite ® Cyanoacrylate Adhesives 410, 411 or 422.See detailed Product Information on Cyanoacrylates on pages 22 and 23.16
Dressing Lead Wires To ConeTo stress-relieve tinsels on the back of the cone andat the terminals on Low Frequency Drivers, several productswork well. For an extremely fast fixture, Loctite ®Light Cure Cyanoacrylate 4303 is the product of choice.This two-part formulation cures in 3-5 seconds, usinglow intensity UV light sources, filling gaps up to 0.75mm.Loctite ® 4303 is medium viscosity and flows well intoboth the tinsel lead and the cone surface. The majoradvantage of these adhesives is speed, making leaddressing possible for the first time on a high speedassembly line.An alternative Light Cure Adhesive is an acrylicformulation, Loctite ® 3175. Designed to achieve rapidtack-free surface cures when exposed to a low intensityUV light source, this product is also excellent when rapidcure speeds are required.Recommended products for Dressing Lead Wires to Cone Assembly:Loctite ® Light Cure Adhesives 4303 or 3175, orLoctite ® Cyanoacrylate Adhesive 410.See detailed Product Information on Light Cure Adhesives on pages 26 and 27.See detailed Product Information on Cyanoacrylates on pages 22 and 23.Assembling Speakers with Loctite ® Adhesives17
