5 Gallon Moisture Cure Reactive Polyurethane Hot Melt Adhesive

5 gallons of moisture curing reactive polyurethane hot melt adhesive is also polyurethane pur hot melt adhesive glue, which is only packaged differently. Its working principle is that the polyurethane prepolymer reacts with the moisture in the air, solidifies and cross-links to form a stable chemical structure. Easy glue application, low melting point, glue can be applied at 110°C. Widely used in edge banding of edge banding machines, composite panel bonding & textile bonding and other solutions, PUR hot melt adhesive has good seasonal resistance: due to its irreversible characteristics after bonding, it will not be affected by environmental temperature changes resulting in creep and brittleness. High toughness, strong initial adhesion, strong permeability and adhesive force, the adhesive strength is 40% to 60% higher than other adhesives under the same conditions, reducing the amount of adhesive used.

1. Features of barreled moisture curing reactive polyurethane hot melt adhesive:

Adhesiveness and toughness (elasticity) can be adjusted, with excellent bonding strength, good high and low temperature resistance, water resistance, abrasion resistance, zero chemical corrosion resistance

And aging resistance, suitable for the bonding of plastics and metals, widely used in woodworking, automobiles, textiles, electromechanical, electronic equipment and other economic fields.

2. Polyurethane hot melt adhesive type

5 gallon moisture curing reactive polyurethane hot melt adhesive (one-component moisture curing polyurethane adhesive), which is one of the types of polyurethane hot melt adhesive. According to the chemical properties, there are two types of polyurethane hot melt adhesives: one is thermoplastic polyurethane hot melt adhesive, and the other is reactive polyurethane hot melt adhesive. Thermoplastic polyurethane hot melt adhesive, also known as hot melt polyurethane hot melt adhesive, is liquefied by heating and solidified by cooling.

Reactive polyurethane hot-melt adhesives are divided into two types: moisture-curing type and closed type. After heating and liquefaction, they are cross-linked and solidified by cooling and moisture reaction. The PUR hot melt introduced today

Adhesive refers to moisture-curing polyurethane hot melt adhesive.

3. Barrel moisture-curing reactive polyhydrogen ester hot-melt adhesive has strong adhesion and high initial adhesion

Since -N CO in the molecular chain of the polyurethane adhesive can react with a variety of active hydrogen-containing functional groups to form interfacial chemical bonds, it is effective for a variety of materials.

Extremely strong adhesive properties. Not only can it bond porous materials, such as foam plastics, ceramics, wood, fabrics, etc., it can also bond a variety of metals, inorganic materials, plastics, etc.

It is an adhesive with a wide range of applications, such as materials, rubber and leather.

4. Outstanding low temperature resistance performance of barreled moisture curing reactive polyurethane hot melt adhesive

At extremely low temperatures, general polymer materials are transformed into glass and become brittle, while polyurethane adhesives can still maintain high peeling properties even below -250°C

Strength, while its shear strength increases significantly with the decrease of temperature.

Purking polyurethane drum PUR packaging: 5 gallon aluminum foil bag (drum), 55 gallon aluminum foil bag (drum), 5kg aluminum foil bag.

PUR hot melt adhesive sizing method

It can be used on special reactive PUR hot melt adhesive machine equipment, with various operation methods.

The above are professional [PUR hot melt adhesive] manufacturers, strength factories, and Purking Adhesive Industry. PUR structural glue can be adjusted appropriately according to customer requirements, and samples are provided free of charge.
