For more than 35 years, ALCHIMICA has been active in the research, development and production of chemicals for the construction and industrial sectors. Remaining loyal to its owner’s values, ALCHIMICA has become synonymous of innovation, reliability and consistency.
Specialized in one and two component polyurethane waterproofing systems, the company has developed a wide range of products that provide solutions for the waterproofing and protection of all kinds of surfaces.
The products are recognized worldwide for their effectiveness and durability, as they have been used in some of the world’s biggest construction projects.
The driving force of the company is its state of the art Research & Development center where the highly qualified scientific personnel of ALCHIMICA, grasping the same innovative philosophy that resulted in the creation of HYPERDESMO decades ago, continues to accord to the challenges of the market.
The result of these efforts are new polyurethane technologies (polyurethane and silylated polyurethanes), as well as products that combine polyurethane with materials of different technologies, such as bitumen, water and cementitious mortars.
is a simple and economic solution for waterproofing and protection. It is a one component, of low viscosity, polyurethane fluid which cures with the humidity in the atmosphere to produce a highly elastic watrproofing membrane with strong adhesion to many types of surfaces. It is based on pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties.
is a result of Alchimica’s investment in new production facilities and polymerization procedures. This investment facilitated the manufacture of a low solvent HYPERDESMO® i.e a non-flammable material without hazardous transportation limitations (non-imo). Furthermore, with HYPERDESMO®-S waterproofing of complex structures, vertical substrates is now easily done even in one coat as rheology is such that it allows easy application of this kind. The product displays minimum bubble formation even in high consumptions.
is a fast-curing, two-component, bitumen-extended polyurethane fluid for waterproofing and protection. It produces a highly elastic membrane with strong adhesion to many types of surfaces and excellent mechanical and chemical resistance properties.It is based on a pure elastomeric hydrophobic polyurethane resin extended with chemically polymerised virgin bitumen.
is a one-component polyurethane fluid which cures with the humidity in the atmosphere to produce a transparent membrane, of increased elasticity, with uniform adhesion over the entire surface. It is aliphatic: no yellowing as a result of direct exposure to sunlight. It is ideal for colour protection of HYPERDESMO® products. It is based on pure elastomeric hydrophobic polyurethane resin, which results in excellent mechanical, chemical, thermal, UV and natural element resistance properties.
is a one component, low viscosity, polyurethane based primer suitable for many different substrates. It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on different substrates, whether of high, low or no porosity (e.g. glass and metals). Additionally, it can be effectively used on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing, thus, the durability of the substrate.
