PVAc and EPI adhesives

PVAc – polyvinyl acetate dispersion adhesive – is the most applicable adhesive in production, used in different gluing applications such as doors, parquet production, veneering, gluing details of solid wood, assembly operations, etc.

The PVAc adhesive that we offer can be classified D2, D3, D4 (standard EN 204/205) and XT6 or XT7 (standard EN 17619) durability class. Some adhesives have moderate resistance to high temperatures and meet the EN 14257 (WATT 91) standard.

EPI – polymer isocyanate emulsion adhesive – similar in appearance to PVAc adhesive, but the characteristics of EPI are several times better than PVAc. They are usually used for gluing window scantlings, double-layer parquet or house balk. The EPI glue line corresponds to durability class D4 according to standard EN 204/205 and EN 14257 ( WATT 91 ) with a large margin and corresponds to durability class C4 according to standard EN 12765. We have EPI adhesives approved and certified for gluing load-bearing constructions.

Urea adhesives are usually used for hot gluing (also in ADS presses), in some cases, with a special hardener, they can also be used for cold gluing. If the glue is liquid, it is always used with a hardener. If the glue is in powder form, then it is dissolved in water and the solution is used for gluing.

Veneering, formpressing – typical operations in which this glue is used. They generally correspond to durability class C3 according to standard EN 12765.

Amino resins adhesives – are marked on the label without any safety phrases (less than 0.1% of free formaldehyde in the glue). Usage is the same as urea glue.

MUF – melamine urea formaldehyde adhesives – their thread is resistant to water and heat, they are usually approved for gluing of load-bearing constructions, CLT – cross laminated timber, for finger-jointing. The glue line complies with all EU (European Union) standards, and can also be approved according to ASTM (USA), JAS (Japan) and AS/NZS (Australia, New Zealand) standards for structural adhesives.

These hotmelts are used for gluing the edges of different materials, “wrapping” with different coatings – based on veneer/carved plywood, paper, PP, etc., as well as for forming and closing packaging boxes.

According to the resins and polymers that are used to make these adhesives, they are classified into these types:

  • EVA – ethylene vinyl acetate hotmelts – the properties of the glue line are average in terms of moisture and temperature resistance.
  • PO – polyolefin based hotmelts – the glue line has moderate or high temperature resistance but average moisture resistance.
  • PU – polyurethane based hotmelts – the glue has high resistance to both high temperatures and water.


Polyurethane dispersion adhesives are used for 3D technology – they can be one-component or two-component. Usually used for PVC or other  kind of foils to be glued to profiled surface.

Most of the above-mentioned adhesives can be partially produced using renewable components (so-called Bio-components, which are not obtained from oil). The Durante Adesives Company has the trademark NATURA to distinguish and mark such adhesives.
