HARDWOOD Marine plywood is an excellent and respected material of extensive aquatic usage, and is also a most controlled timber product for boats up to 20 metres, both racing and pleasure. In addition, it has received wide acceptance in commercial and naval vessels and is also extensively used in commercial fit-out and joinery works. Marine plywood is manufactured with highest face quality on two sides. Veneers are selected because of freedom from defects and peeler checks, as well as high mechanical strength and suitability for permanent bonding. Quality controlled glue line is another important aspect of plywood in a boat. The glue bond must be permanent, and must maintain its strength and durability under the most exposed conditions over the full life of the boat. Phenol formaldehyde resin bonds, achieved under controlled heat and pressure in the hot press, have proved over 50 years of laboratory testing and under extreme exposed conditions to perform without deterioration.
COMBI Marine plywood glue must be the best permanent waterproof, gas-resistant and weather-resistant glue (WBP glue). The glue for outdoor plywood can be the best permanent waterproof and resistant weatherable rubber, or it can be general waterproof and resistant to cooking and weathering adhesive.
3.Grade of wood/backboard (*Note 1)
The face/back plate of COMBI marine plywood must not have any defects (a small amount of needles are allowed). However, for outdoor plywood with a slightly lower grade, defects on some face/back plates (such as dead quilting, quilting, etc.) are allowed (such as C/D grade outdoor plywood).
COMBI Marine plywood: In general, the long middle plate should be a whole piece; if you need to splicing the core board, you can use the vertical spelling method, but you can't use the end spelling method.
