Finnish furniture manufacturer Isku started using Kiilto’s biobased Kiilto Pro WRX 3070 adhesive, developed specifically for the furniture industry. D3 class PVAc adhesives are used in the wood manufacturing industry for products such as doors, parquet flooring, kitchen and bathroom worktops, and shelving.
The new WRX 3070 adhesive is pH neutral, so it will not stain the wood veneer to be bonded. The adhesive also has a low formaldehyde content, which means safer production and greater responsibility in the use of the product throughout its life cycle.
A major problem in the furniture industry is the discolouration of wood veneer caused by the acidic pH of adhesive and the resulting loss of wood. For example, in oak veneering, acidic adhesive can discolour the glued area, resulting in these products having to be withdrawn from production.
“Kiilto’s WRX 3070 adhesive was developed to solve this problem. We managed to reduce the degree to which the adhesive can permeate the veneer by modifying the structure of the adhesive. In product development, we have succeeded in optimising the absorption and penetration of the adhesive without compromising on its other properties,” says Kiilto’s RDI Manager Jukka Jokela.
Kiilto’s advanced PVAc adhesive also allows for thinner veneers to be used. This translates directly into material and cost savings.
Kiilto Pro WRX 3070 contains up to 95% less formaldehyde than commonly used adhesive products. It means that WRX 3070 has lower formaldehyde content than apple, for example.
Kiilto Pro WRX 3070 adhesive has an extremely short pressing time, and does not require high temperatures during the gluing process. The low temperature saves energy, while the reduction in pressing time and the uniformity in surface treatment make the whole gluing process considerably more efficient. It has been estimated that a shorter pressing time can increase production efficiency by up to an average of 20%.
Kiilto, a family-owned group from Finland, develops, produces and markets chemical industry solutions in four business areas: construction, industrial adhesives and fireproofing, professional hygiene, and consumer goods.
