This transparent Laminaion glue has particularly short structure, which enableshigh speed tissue machinery. the special adhesive film properties and structure of the producthave been carefully developed to give optional penetration, excellent workability and clean running. This charateristics give high tack at high speeds. Furthermore the product does not penetrate the sheets and therefore does not contaminate the cylinders. The film is particularlysoft. The dried film is water soluble.
Liquid sodium silicate products are slightly sticky, but they have only moderate tack compared to many organic pressure sensitive adhesives. As the water evaporates, liquid silicates become progressively tackier and more viscous. Generally, only a small portion of the water (several percent by weight) needs to evaporate before the adhesive exhibits good handling strength. Therefore, sodium silicate adhesives are often employed in applications requiring high machine speeds and fast setting characteristics. The effects of water evaporation on the viscosities of several liquid sodium silicate products are shown in the table below.
