Overview Show

SPRAYTEC 421 is the latest generation of high performance, extended open time spray hotmelt adhesive. Features include outstanding spray- ability and it is clear in colour.

When sprayed, SPRAYTEC 421 can be used for bonding packaging foams, bubble film, vacuum foamed mouldings, upholstery foams, cotton-backed vinyl and many other fabrics.

When applied in bead or dot form good bonds can be achieved on most plastics. Bonds can also be achieved on polypropylene such a ‘Corex’ when the adhesive is applied at over 200˚C however care must be taken not to leave the equipment on unused at these high temperatures to avoid adhesive melt back.

All parts of this adhesive have been approved by the American F.D.A under C.F.R 21.175.105 (adhesives).

Important: Hot Melt Adhesives do have limitations! Being a thermoplastic product hot melt adhesives soften with heat and return to a solid state by the loss of heat. With this in mind, standard hot melt adhesives are not recommend for applications subjected to heat or direct sunlight. However we do offer grades with high heat resistance. Water and hot melt adhesives are a bad combination – standard hot melt adhesives are not waterproof and should be avoided for external applications. On saying this, we do have PUR adhesives that can be use externally and can even be dry cleaned. We strongly recommend that you thoroughly test the product and satisfy yourselves that the product is suitable for your application. This product suggested uses are a generalised suggestion and other factors may play a role in achieving the required bond, e.g. heat resistance, chemical resistance, gap filling, surface area to glue, open time or a degree of glue flexibility may be required etc.
