Hylomar Pre-Applied Adhesives and Sealants
Hylomar manufacture a range of pre-applied adhesives and sealants which are used in original equipment manufacture. The use of pre-applied adhesives and sealants saves the equipment manufacturer time and hence costs in their particular assembly processes. Hylomar pre-applied adhesives and sealants replace conventional sealing and locking methods such as ptfe tape, sealing washers, locking pins, locking nuts, locking washers, anaerobic adhesives and torque tension fluids. The product range includes pre-applied underhead sealants, thread sealants,threadlockers and torque tension coatings.
Hyloloc 406 is a high strength, water based, pre-appied threadlocking adhesive. Hyloloc 406 is applied to the thread of the fastener by a flow coating method and is then dried by hot air blowers or ovens to leave a dry to the touch pre-applied adhesive. The water based formulation means that no hazardous solvents need to be used by the applications company. When dried the fasteners can be stored or shipped ready for use. Hyloloc 406 on-part life is up to 4 years when stored in dry conditions.
When the pre-applied fastener is screwed in place the Hyloloc 406 reacts to form a resiliant polymeric adhesive which secures the fastener in place. The rapid reaction rate of the adhesive ensures a very high strength is achieved within 1 hour of assembly. Hyloloc 406 is approved for use in automotive applications by Ford.
Hyloseal 204 is a water based pre-applied threadsealant. The product is applied to threaded fasteners in an automatic production line by means of flow coating the components and then drying the sealant by means of hot air blowers, infra red or air circulating ovens. As the product is water based the applications company has no concerns over exposure to hazardous solvents. The coated fasteners can then be stored ready for use for up to 4 years in dry conditions. Semi automatic methods or even manual application of the product can be used for specialist low volume applications.
Under Head Sealing
Hylomar underhead sealants are designed to replace conventional mechanical forms of underhead sealing such as copper, aluminium, rubber or composite washers. When assembled the underhead sealant is forced into the gap between the head of the bolt and the component assembly to form a seal. The underhead sealant has good chemical and moisture resistance to form both a fluid and an environmental seal. A licenced application process is used to form the precise bead dimensions ensuring no excess product is applied to the component. The process is suitable for application to bolts, plugs, rivet and rivnuts.
