Types of plywood glue

(1) According to the different composition of the glue, there are several kinds of glue for building plywood as follows:

Urea formaldehyde glue: moisture-proof glue / used for interior decoration and furniture, not for outdoor use.

Melamine glue: dampproof, water resistant, climate resistant / can be used outdoors or indoors, but not often soaked in water.

Phenolic glue: moisture-proof, excellent water boiling resistance, weather resistance / can be used outdoors or indoors, can withstand outdoor wind and rain.

(2) According to the environmental protection grade, the glue used for plywood can be divided into E0 grade, E1 grade and E2 grade (as well as the unqualified glue that can’t even reach E2 grade). E0 is the highest environmental protection level. The plywood made of E1 grade glue can be directly used indoors.

High quality urea formaldehyde glue / melamine glue / phenol formaldehyde glue can reach grade E0 and E1, that is to say, they can be directly used indoors.

(3) Environmental protection suggestions:

1. If you want to make general indoor wood products, you can use E1 (or even E0) urea formaldehyde glue; if you want to make the wood products more waterproof and moisture-proof, you can use E1 (or even E0) melamine glue.

2. If you want to make wood products for outdoor use, you can use E1 (or even E0) phenolic glue.
