Optimized logistics
Supplying a dry powder blend instead of a liquid adhesive reduces product weight. This improves shipping efficiency and can reduce carbon emissions across distribution.
PRODUCT / CASEIN ADHESIVE
Lica
A 100% natural-origin powder adhesive based primarily on casein. Lica redesigns traditional lime-casein adhesion for modern interior installation by applying dissolution-control concepts from pharmaceutical formulation technology.
Under alkaline conditions, casein can react with mineral components to form a strong adhesive layer that is less likely to return to water after drying. This principle has long been known in lime-casein adhesive systems.
Conventional lime-casein adhesives, however, can be difficult to dissolve and can leave too little working time for modern interior installation methods.
APIA applies dissolution-control thinking from pharmaceutical formulation technology and redesigns the system around casein, alkaline components, and mineral ingredients reacting under optimized conditions.
Material Logic
Why a powder premix?
Lica is developed as a natural-origin adhesive system that can be distributed stably in powder form and dissolved in water on site before use. Compared with liquid products, this reduces shipping weight and spoilage risk during distribution.
For highly absorbent and strongly alkaline substrates such as lime-plaster wallpaper, the design aims to balance spreadability, positioning time, and dry adhesive strength while moderating rapid water migration.
Prepared State
Prepared as a wallpaper adhesive for installation.
Lica is designed to be stored and distributed as a powder, then dissolved in water for wallpaper installation. The photo shows the wallpaper adhesive after preparation with water.
This powder format aims to reduce the weight and spoilage risks associated with liquid products while allowing workers to prepare fresh adhesive on site.
Benefits

02
03
Designed for both installation and distribution.
Reduced spoilage risk
Because the product contains no water during storage and distribution, spoilage risk is reduced. On-site mixing enables workers to use freshly prepared adhesive without relying heavily on storage additives.
Workability through dissolution control
By applying dissolution-control technology from pharmaceutical formulation, Lica aims to address the low solubility and short working time that made traditional systems difficult to use in modern installation.
