Yes, PUR hot melt adhesive can be used for certain PET lamination applications involving SPC and other engineered substrates, provided that the adhesive grade is compatible with the specific materials and process.
SPC and other substrates with relatively low surface energy may require appropriate surface preparation to achieve reliable adhesion. Depending on the substrate, surface treatment such as corona treatment, plasma treatment or other adhesion-promoting methods may be considered.
Before mass production, manufacturers should test the adhesive under actual production conditions.
Important factors include substrate surface condition, adhesive grade, application method, coating conditions, pressing conditions and curing time.
Not every PUR adhesive grade is suitable for every PET or SPC application, so product-specific compatibility testing is recommended.
