| Cold Press |
Cold press laminating, curing with pressure only and no heat, is the most widely used procedure for sheet goods.
Common applications involve high-pressure laminates, wood veneers, metal skins, and fiberglass panels bonded to a core of particleboard, medium-density fiberboard,
honeycomb and inorganic composites.
H.B. Fuller offers a wide range of adhesive systems for laminating applications.
Depending on the application needs, products can range from waterbased Rakoll® adhesives, reactive hot melts, and liquid moisture curing polyurethanes.
These one-component, moisture curing polyurethane adhesives are designed for laminating metal skins to a variety of core materials.
Our products feature low viscosity for ease of application at ambient temperatures, and fast set speed.
Since products are 100% solids, they can replace solvent based contact adhesives with complete elimination of VOCs.

| Hot Pressing |
Hot pressing involves using heat from a hot platen to accelerate the cure of a single laminate-to-core application.
Temperature and dwell time depend on the heat source of press, the substrates and the adhesive.
H.B. Fuller offers waterbased Rakoll® adhesives for a variety of application needs depending on desired water resistance;
porosity and surface characteristics of the veneer; closed assembly time required to fill a platen for pressing; and heat resistance.
|
| Contact Solvents |
H.B. Fuller supports a range of solvent-based contact adhesives,
for spray application on both surfaces and allowed to dry to touch for optimal adhesion, used to bond steel skins, HPL or fiberglass to various cores , usually EPS.
|
| Radio Frequency Gluing |
H.B. Fuller offers Rakoll® waterbased adhesives for use with RF curing,
including batch process and continuous process edgegluing of panels and assemblies.
Products in this category will typically yield Type II water resistance, and are available in filled versions that are resistant to ìbleed throughî when used on porous veneers.
|
| Abrasion Strip Attachment |
H.B. Fuller offers a wide range of resilient and hard-wearing adhesives well suited to attaching abrasion strips.
Depending on the application needs, products can range from waterbased, reactive hot melts, and moisture curing polyurethanes.
|
| Membrane Pressing |
Membrane Pressing is the use of a heated or unheated formable membrane (flexible blanket)
to allow compression and adhesion of formable substrates, such as vinyl, paper or other thin veneers, over contoured or routed cores.
H.B. Fuller offers specially formulated PUD (water based polyurethane dispersion) adhesives for this market,
that exhibit excellent spray patterns at low gun pressures that reduce overspray, demonstrate superior hold out on porous edges of MDF for consistent film formation.
The wide temperature reactivation window lets you work with the variety of membrane presses and operating temperatures found in the market place.
|
| Fingerjointing |
Bonding finger joints requires strong adhesives that stand up under demanding conditions.
H.B. Fuller offers water-based products for use with wheel or extrusion applicators that are extremely fast setting and machine cleanly to keep your production lines running efficiently.
Also, liquid moisture curing polyurethane adhesives offer alternatives to traditional manufacturing practices.
Physical properties include high strength and flexibility, as well as excellent adhesion.
Bonds are quick setting and are extremely water resistant. H.B. Fuller finger joint adhesives feature low formaldehyde levels and work equally well with ambient or RF curing.
|
| Molding Primer |
H.B. Fuller offers a variety of water-based primers for application to molded lumber to facilitate painting
by hiding the color variations in the lumber and providing a uniform base for additional finishing.
|
| General Assembly |
H.B. Fuller offers a line of water-based,
hot melt and hot melt moisture cured assembly adhesives with proven track record for edge and face gluing,
hand assembly with glue bottles, doweling and other general assembly applications.
