How to choose and use polyvinyl acetate Woodworking Adhesive in woodworking applications is a matter of concern to many carpenters. Today we will share with you Woodworking Adhesive selection and use of skills.

Woodworking Adhesive is not cheap, but the Woodworking Adhesive does not exist this problem

Most of the ordinary glue, such as yellow glue, can be used to meet a variety of tasks. We all know that Woodworking Adhesive is very easy to use is also very common, but if you can better understand the glue formula, allows us to maximize the effectiveness of the performance of glue.

PVA Woodworking Adhesive is the academic name of polyvinyl acetate, this adhesive was widely used in the Second World War. Its predecessor was animal glue, has been popular for centuries, the earliest can be traced back to the ancient Egyptian pharaoh Tutanka mausoleum in the furniture. Polyvinyl acetate has many advantages: long shelf life; long life; no heating. At the same time, polyvinyl acetate can be used to change the formulation, so as to adapt to different work and characteristics, such as water resistance and gel time. Polyvinyl acetate Woodworking Adhesive can bond all the joinery products, many curved plywood and most of the veneer panels. And almost all of the wood on the use of the results are very good, including plywood and MDF. But try to avoid the use of polyvinyl acetate on most tropical woods, because the oil-rich wood will affect the adhesion of the glue.

Polyvinyl acetate Woodworking Adhesive is more suitable for clean surfaces and tight joints

Want to know more about the advantages of polyvinyl acetate glue, you have to know how it is used. One of the first key factors to know is absorption. When the particles floating in the water will be absorbed into the surrounding wood fiber. When the water evaporates and the glue becomes hard, the adjacent wood is tightly adhered. This is why the just sawing, grinding or planing after the wood can be intact bonding reasons. If a week or more, the contaminants from the inside of the wood will prevent the glue from penetrating.

Another key factor in the potency of the Woodworking Adhesive effect is the thin and continuous coating of glue at the junction. Polyvinyl acetate glue is not a good sealant. This means that it is necessary to obtain as much as possible a tight gluing face and an external strong gripping force. When you can not directly hold two joint surfaces, such as the dovetail or the connection between the dowels and the dowels, the joints must be kept in good condition.
