An adhesive that ensures a very moisture-resistant bond of wooden elements is very necessary because high humidity can be both indoors and outdoors. Pieces of furniture in bathrooms or kitchens, anything that involves wood furnishings in these areas, need to withstand higher humidity than in other rooms. Likewise doors, windows or garden furniture need the elements to stay stuck together even if they are battered by rain. An adhesive with such strength is a D4 adhesive. It falls into this category because of its qualities. I intend to tell you more about this type of adhesive below.<\/p>\n

What is a D4 adhesive and how is it different from a D3 adhesive<\/strong><\/h5>\n

I was telling you recently about a improved D3 adhesive for use in winter conditions<\/a>. The area code D3<\/strong>\u00a0means, according to European standard DIN EN 204<\/strong><\/a>, that it can be used for interior construction with short-term exposure to damp or damp environments, for exterior construction in mild climates, for jointing steps, doors or windows installed in weather-protected areas.<\/p>\n

Unlike D3, D4 adhesive<\/strong>\u00a0is used for joints that need much higher moisture resistance. It can be used both indoors (bathroom, kitchen) and outdoors (garden furniture). It is a very suitable adhesive for solid wood panels<\/a>, laminated wood, exterior windows and doors. One such adhesive is Tiszabond 1kD4-D cod 4133<\/strong> of the Szolvegy T\u00e2rgu Mure\u0219<\/strong><\/a>.<\/p>\n

\"adhesive<\/p>\n

Main features of Tiszabond 1kD4-D 4133 adhesive<\/strong><\/h5>\n

The adhesive is a single-component, aqueous dispersion of polyvinyl acetate (aracite). It has improved grip on the substrate<\/strong>, which results in a much higher bonding quality.<\/p>\n

The film formed after curing is transparent and highly elastic<\/strong> which is a big advantage for manufacturers of composite panels. What is this advantage? Apart from the fact that the adhesive film is not visible at the joints, it substantially increases the average tooling (planer) uptime, of the machines<\/a>).<\/p>\n

The hard films formed when using inelastic adhesives attack tools and shorten their life. When the film is elastic the hardness is lower and the tools suffer less. The elasticity of the Tiszabond adhesive film is due to the fact that the adhesive does not contain fillers (generally chalk).<\/p>\n

But the main feature is moisture resistance<\/strong>. The formed adhesive film has a very good water resistance and is, according to DIN EN 204, a D4 adhesive. The moisture resistance is comparable to that of a D4 adhesive with hardener. Despite being one-component it hardens after a short pressing time, resulting in a solid, firm bond.<\/p>\n

Where Tiszabond 1kD4-D 4133 adhesive can be used and where not<\/strong><\/h5>\n

\u2295<\/span> The adhesive can and should be used for gluing wood elements used indoors in environments with very high humidity (bathrooms, kitchens). Rising temperatures in these areas amplify the effects of humidity.<\/p>\n

\u2295<\/span> It is very suitable for gluing wood panelling, wooden steps or laminate flooring.<\/p>\n

\u2295<\/span> It is recommended for making solid wood panels and for bonding veneer to wood or chipboard panels.<\/p>\n

\u2295<\/span> Being resistant to external conditions, it can be used for gluing laminated wood to make windows, wooden door panels for exterior use. It is also recommended for gluing garden furniture.<\/p>\n

\u2297<\/span> But there is one area where polyvinylacetate-based adhesives are not recommended. These are obtaining the supporting beams.\u00a0<\/strong>Builders need to differentiate support beams from other beams, and manufacturers MUST NOT use aracite-type adhesives in their manufacture<\/strong>. Szolvegy recommends one-component D4 (1kD4 PU) polyurethane adhesives certified for this purpose.<\/p>\n

What you need to know when using this adhesive<\/strong><\/h5>\n

I used to say that any product, no matter how good it is, never works wonders. That's why, to have a perfect moisture-resistant bond, several parameters must be taken into account:<\/p>\n
