Plywood Adhesive Glue Types Home   
For wood Panel, the Glue is the key ponits relating to the Property such as Bonding Strength, Water Absorption and Formaldehyde Emission etc, which effect on Accordance of Project Requirment, Property of Down-Steam Products, even Accordance with Regional Regulations.

Different Glue shoud be choosed based on different purpose or requirment. Following are Glue Types&Grade we used in Panel Production:

Exterior Glue:
---Grade 1: WBP Phenolic Glue
---Phenol-formaldehyde glues are standard for exterior. With glue properly formulated for exterior use
    and suitably employed, no exposure conditions or laboratory testes are known which will degrade
    hot pressed phenolic glue bonds without destroying the adjacent wood layers. Phenolic glues are
    also used for impregnating veneers.

---Grade 2: WBP Melamine Glue
---Melamine formaldehyde glues are not extensively used for plywood gluing but are used where a
    high-grade bond is required, and where black phenolic glues cannot be tolerated.They are used to
    fortified urea-formaldehyde glues to increase the weather resistance of the bond. The largest
    application of the melamine formaldehyde resin is in the production of decorative overlays


Interior Glue:
---Grade 1: MR&E0 Glue (Formaldehyde Emission under 0.5mg/L)
---Grade 2: MR&E1 Glue (Formaldehyde Emission under 1.5mg/L)
---Grade 3: MR&E2 Glue (Formaldehyde Emission under 5.0mg/L)
---Urea formaldehyde glues are extensively used for interior and intermediate grade bonding, which
    covers the majority of hardwood plywood produced. Formulas differ somewhat and can be adapted
    to meet specific conditions
