Silikal MMA mortar systems

Applications

Silikal reactive resins are used to produce both heavy-duty and decorative floor coverings for almost all industrial sectors, as well as mortar systems for extremely fast and highly durable concrete repairs. Silikal has specialized in methacrylate reactive resin technology and has proven itself on many millions of square metres for 70 years.

Unique features

The high-quality Silikal mortar systems differ from other mortars as they can be installed very quickly, namely already after approx. 1 hour after completion of the work. This is achieved by the unique properties of the binder used, the Silikal reactive resins based on methyl methacrylate, which harden very quickly and almost independently of the temperature. These two most important advantages clearly set Silikal reactive resin mortar systems apart from other resin mortars (e.g. based on epoxy resins).

Benefits of the reactive resins of the Silikal mortar systems

PMMA reactive resins from Silikal have significant advantages over other common reaction resins such as epoxy resin or polyurethane resin, such as:
- Rapid curing of the reaction resins and immediate full load-bearing capacity of the floor.
- Curing even at low temperatures (in some cases down to -10 ºC) and therefore easy to apply even in winter or in cold storage halls.
- Excellent adhesion to the Surfaces and problem-free recoatability.
- Health safety of the cured mortar.

Repair of concrete with mortar

It is well known that mineral mortars are used to repair concrete. Cement is usually used as a binder for sand and possibly other aggregates, and the mixture sets hydraulically with water. If necessary, additives are added to improve certain properties of the concrete. Cementitious mortars can be used on wet substrates,
- but only harden above 0 ºC,
- require long setting times
- and have low flexibility and low resistance to wear and aggressive media.
It is astonishing how little it is known that concrete can also be renovated with mortars whose mineral aggregates are not bound by cement but by synthetic resins. Probably people do not trust synthetic resins with the properties of concrete, especially as far as compressive strength is concerned. The opposite is true, because synthetic resin-bonded mortars sometimes have much higher strengths than concrete itself and also surpass most of the other performance characteristics and properties of concrete. Of course, the price is not comparable, so that reactive resin mortar systems are not intended for large-scale use, but mainly for refurbishment purposes. However, taking into account the speed of the work itself and the immediate use, the total cost of refurbishment in such cases is usually lower.

Optimum adhesion with the Silikal mortar systems

The Silikal R17 mortar system consists of the filler component in a 15 kg bag and the corresponding hardener liquid in a 2 litre can. Both components are mixed to produce a pourable mass that is poured into the area to be repaired. For repairs on vertical or sloping surfaces, there is the mortar system SILIKAL^® R 17-thix. Of course (as with all other repair materials), preparation of the substrate is necessary to achieve a perfect quality of the repair. For optimum adhesion, a primer coat of e.g. SILIKAL^® R 52 or R 51 is required. For example, one standard set of SILIKAL^® R 17 allows the restoration of an area of approx. 1 m² with a thickness of approx. 1 cm. SILIKAL^® R 17 reactive resin mortar is also supplied in special grades.

Individual appearance of Silikal reactive resin mortar systems

SILIKAL^® 17 reactive resin mortar is pigmented in "concrete grey" as standard, but can be supplied in other colours if a minimum quantity is exceeded. SILIKAL^® R 17 can also be used to produce any layer thickness, in which case coarse to very coarse aggregates (gravel) are also used. Surfaces made of SILIKAL^® R 17 reactive resin mortar can also be overcoated to achieve a more attractive appearance. SILIKAL^® R 17 is tested and certified for various applications.
