The inspection precautions before the use of PUR hot melt adhesive are as follows: 1: First check whether the vacuum state of the PUR hot melt glue package is intact, and stop using it if any air leakage is found; 2: Preheat the glue without tearing off the aluminum foil (label) (usually 5 minutes to
Can PUR glue be suitable for the bonding of MDF? No, PUR (Polyurethane Reactive), the full name is moisture curing reactive polyurethane hot melt adhesive. The mechanism of PUR hot melt adhesive is that the polyurethane prepolymer reacts with moisture in the air, solidifies and crosslinks to form a stable chemical structure. Compared with EVA
Urea-formaldehyde resin is mainly used to prepare amino alkyd baking varnish with alkyd resin to improve the hardness and dryness of the paint film. It can be combined with non-drying alkyd resin to make acid-cured amino paint for wood furniture finishing. However, the weather resistance, water resistance and gloss retention are slightly worse. It can
What is plywood? Plywood is a multi-layer board-shaped material formed by peeling wood sections into veneers or sliced into veneers, and then using adhesives to glue adjacent veneers whose fiber directions are perpendicular to each other. Blockboard is the second largest sub-variety of plywood subdivisions. It is made of high-quality natural wood after heat treatment,

It is generally believed that the cabinets made by woodworking are space-saving and durable, but the disadvantage is that they are poor in aesthetics. Especially if the edge banding is not handled well, it will not only be ugly but also affect normal use. If you plan to let the woodworker hit the cabinet, then
Hot-melt adhesive is a big category, PUR hot-melt adhesive is one of them, most hot-melt adhesives are heat-operated, can be reheated after bonding, and are reversible, while winlong-PUR hot-melt adhesive is wet Gas-reactive hot-melt adhesive, heated operation, will react with the moisture in the air after bonding, and it will be irreversible after the reaction
Two-component polyurethane adhesives are usually composed of an isocyanate component (curing agent) containing NCO and a hydroxyl component (main agent) containing hydroxyl groups. When using, mix the two liquid components according to a certain ratio, use NCO and OH to react to form solid polyurethane, and then use the polar group of polyurethane to form
Epoxy glue is an important thermosetting resin glue. Especially because of its excellent physical and mechanical properties, electrical insulation properties, chemical corrosion resistance, heat resistance and bonding properties, the epoxy resin adhesive prepared with it is known as "multi-purpose adhesive" and can be widely used in chemical industry, Industrial fields such as light industry, water
