There are numerous types of plywood glue on the market today, each with its distinct properties. Users can select the best material for each type of product and application.
Urea Formaldehyde glue
This is a synthetic glue made by reacting Urea and Formalin at the proper temperature using reaction catalysts/inhibitors such as Formic Acid and Sodium Hydroxide to produce Monomer. The monomer has very high bonding characteristics and can form solid polymers in acidic conditions.
This glue stands out for its great adherence and quick drying speed, as well as its low cost in comparison to other synthetic glues. UF industrial plywood glue is widely used in the manufacture of plywood, fiberboard (MDF, MFC…), joinery, and chipboard for the interior market. We can choose glue according to E0 to E2 standards based on product standards and market.
Melamine Urea Formaldehyde Glue
Melamine Urea Formaldehyde industrial plywood glue (abbreviated MUF) is another modification of Urea Formaldehyde (UF) glue used to improve UF glue’s weakness. MUF glue production is identical to UF glue production. To denature the glue, Melamine is added during the heat reaction between Formalin and Urea under the catalyst/inhibition of Formic Acid and Sodium hydroxide. The inclusion of Melamine causes this alteration, resulting in a diversity of cross-links in the product after curing, drastically altering the properties of the glue.
This glue has excellent adhesion and endurance, and it is far superior to UF glue in terms of water resistance. However, when compared to other types of plywood glue, the price is relatively high.
Phenol Formaldehyde industrial wood glue (abbreviated PF), sometimes known as Phenol glue, is a Phenol and Formaldehyde-based adhesive compound. The heat interaction of phenol and formaldehyde molecules in alkaline or acidic conditions results in extremely tight and long-lasting bond chains. This adhesive is primarily used to press industrial boards such as plywood, building formwork, fiberboard (MDF, MFC, HDF), and other outdoor-use boards.
When different phenolic (phenolic, methyl hydroxybenzene, xylenol, resorcinol) and aldehyde groups (formaldehyde, acetic aldehyde, furfurol…) and aldehyde groups (formaldehyde, acetic aldehyde, furfurol…) groups are used in different ratios, the catalyst alters and produces different products. PF glue products have distinct applications and qualities.
High durability and water resistance are two outstanding qualities of plywood made with this sort of adhesive. A well-made casing can tolerate 72 hours of boiling without splitting or damage. As a result, this is an essential glue for outdoor applications.
Each form of plywood glue will have different benefits and drawbacks. AMC Vietnam will compare the benefits and cons of each type of adhesive to help you better understand these three forms of plywood glue. You may then better comprehend the different types of glue and answer the question, “What glue should be used to suit each different need?”
