It is not a secret for anyone that the furniture is held not only by screws. There are such details and connections of furniture structures where it is simply impossible to do without glue. For furniture production, industrial joiner's glue is used, which must guarantee the strength and strength of the joints, as well as environmental safety.
Joiner's furniture glue may be of plant origin of animal origin and synthetic. Plant-based formulations are made from wood resins, starch and cellulose. As a rule, they do not have good water resistance and antibiological resistance.
Animal-based formulations can be based on albumin (a product from animal blood), glutein (a product from bones, flesh and fish products). Such products are susceptible to the action of water and biological flora (fungus). In addition, from casein glue types, the wood at the gluing site can darken strongly, and inexpensive casein glue types initially have a darker color than wood. Hutein varieties are considered the most popular of the natural species.
In industrial and private furniture production, synthetic grades have recently become more and more in demand, as they are characterized by optimal qualities, as well as ease and ease of use.
Often in the furniture industry they use furniture glue and PVA emulsions, which can have three types of consistency - low-viscosity, medium-viscous and high-viscosity (HB, SV and BB). The advantages of PVA include lightfastness and plasticity of the adhesive joint, the disadvantages - instability to water, frost and heat above 60 ° C.
BF-2 glue is suitable for gluing wood, it has an optimal range of qualities - it is not susceptible to the action of fungus, oils, gasoline, and is waterproof. This type should be used after staining the wood.
When gluing furniture seams, grades of glue K and K-17 are also used, they provide a strong connection, are characterized by water resistance, heat resistance, are not susceptible to the action of various bacteria and fungi.
As practice shows, the use of modern synthetic substances is more profitable and reliable, since they have the most suitable qualities. In addition, depending on the needs and the desired type of seam, different types of adhesives can be used in one product.
