VISIOMER® - METHACRYLATEs FOR CONSTRUCTION APPLICATIONS
Acrylic materials based on methacrylate monomers have captured a good market share in the construction industry. They serve as binders for concrete admixtures, liquid water proofing compounds, industrial flooring and reactive road marking systems as well as concrete repair compounds. They are easy to process and cure rapidly even at low temperatures
Concrete admixtures are materials that are added to concrete during the mixing process in quantities not exceeding 5 wt% of cement. This way, concrete properties can be altered in the fresh and hardened state. Polycarboxylated ether polymer-based superplasticizers are well-known in the cement/concrete industry as special types of concrete admixtures for improving pumpability (rheology) and strength characteristics of fresh concrete.
Cracks in concrete can occur for various reasons, such as setting or shrinking, or because of a faulty design or problems in the construction process. Water bearing cracks are cause for particular concern because they can lead to corrosion of reinforcements, and jeopardize the building’s safety. Methacrylate crack injection systems offer a simple and effective solution for filling and sealing the cracks.
Chemical anchors are a combination of mechanical parts and adhesive substances that work together to bond old concrete to new concrete, or bolt items, such as rails or mechanical equipment, to concrete surfaces. Using methacrylate reactive resin compositions as binders for the art of chemical fastening is common practice. The reactive resin compositions in question are two-component systems, in which one component comprises the reactive resin and the other the curing agent.
VISIOMER® methacrylate monomers can be found as a raw material in various adhesive and sealant formulations. Most popular are reactive adhesives based on methacrylates, though pressure-sensitive adhesives and sealants, e.g. for construction applications, also contain our VISIOMER® products.
VISIOMER® GLYFOMA is a new reactive diluent and can be used when low-odor proper are required for flooring or chemical anchoring.
