Hot Melt Adhesives

Collagraf has consistently invested time and resources in the research and development of new hot melt technologies to meet customer needs and expectations. The market-focused approach has driven Collagraf to implement a continuous process of innovation both in production processes and in the search for new adhesive formulations. For many years, in addition to EVA-based hot melt adhesives, Collagraf has been producing POLYOLEFINIC (PO) hot melt adhesives, ACRYLIC (EBA) hot melt adhesives, and EVA hot melt compounds mixed with “PRESSURE SENSITIVE” adhesives (EVA + PS). The product portfolio is further complemented by POLYAMIDIC (PA) hot melt adhesives.

Collagraf’s hot melt adhesive formulations are produced in all possible formats to be used for any type of application, both industrial and hobby, with any type of applicator, whether industrial/automatic or manual/mechanical. A peculiarity that distinguishes Collagraf from many other companies in the sector is the fact that the various hot melt formulations are produced in different formats: STICK (diameter 7, 8, 11, 12, 15 mm), CARTRIDGES diameter 43 mm, GRANULES, BLOCKS, and PILLOWS for industrial applications where melters, plotters, automatic or semi-automatic machines are used.

EVA-BASED HOT MELT ADHESIVES

Collagraf produces dozens of formulations of EVA-based hot melt glues for various markets and multiple applications: packaging-paper converting, crafts-DIY, construction, packaging, assembly of plastic materials, furniture, and wood processing, bonding of textile fibers.

POLYOLEFINIC (PO) HOT MELT ADHESIVES

The new and innovative metallocene-based hot melt adhesive formulations offer several advantages during the bonding phase of supports and plastic-coated surfaces (polyester, polypropylene, and polyethylene), painted and lacquered surfaces, ensuring rapid setting times and very strong resistance to high temperatures.

ACRYLIC (EBA) HOT MELT ADHESIVES

EBA-based hot melt adhesives were developed about ten years ago to allow for high adhesion on shiny and rigid surfaces (plastic, wood, bricks); thanks to their strong adhesion, mechanical elasticity, and long open time, they allow the bonding of heavy and large materials.

EVA + PRESSURE SENSITIVE (EVA + PSA) HOT MELT COMPOUNDS

Collagraf produces innovative hot melt formulations in Ø 12 and Ø 43 mm stick formats that combine EVA raw materials and Pressure Sensitive adhesives, thus providing high holding even on non-bondable surfaces and an extremely long open time.

PRESSURE SENSITIVE ADHESIVES (PSA)

Pressure Sensitive hot melt adhesives are characterized by being always active adhesives with permanent tackiness and a long open time. They allow bonding on particularly large surfaces. They are mainly used in labeling, publishing, and specific packaging needs, as well as in various construction contexts (production of insulating panels and window support structures).

POLYAMIDIC (PA) HOT MELT ADHESIVES

Polyamide-based hot melt adhesives are used in specific sectors and for special applications where, in addition to strong bonding resistance, very high temperature resistance is also required (electronics, automotive, hair extensions).
