Dry Adhesive Powder

Dry adhesive powder

Dry Adhesive Powder is one of the most widely used chemical materials across various industries, particularly in packing, construction, textiles, wood, and paper sectors. Contact Us.
This type of adhesive is supplied in solid, powdered form, and when required, it is activated by the addition of water or specific solvents to exhibit its adhesive properties. Contact Us.
Below, we examine in scientific detail its concept, composition, applications, and advantages.

Applications

Wood and furniture industry: For cold or hot pressing in veneering MDF, lentron and plywood sheets.

Shelf Life

At least one year at 25 °C.

packing

25 kg polypropylene bag

Dry adhesive powder is usually made from thermoplastic or thermosetting polymers that are soluble or dispersible in water. Common compositions include:

Polyvinyl acetate (PVA)
Ethylene-vinyl acetate (EVA)
Polyacrylates and acrylic copolymers
Natural resins and cellulose derivatives (such as carboxymethyl cellulose)

Color: White to cream, sometimes transparent after dissolution
Particle size: Typically between 50 and 150 microns
Working solution pH: neutral to slightly alkaline (6.5–8.5)
Activation temperature: Usually ambient temperature, but some types require heat.
Adhesion and final strength: Excellent, depending on the type of polymer and surface used
