2 part Polyurethane Floor Coating Waterborne (Water – Based)
Unithane W/D Polyurethane coating waterborne is a two component pigmented water dispersed coating. It has a very good adhesion to most sound substrates and provides a dustproof easily cleaned surface, with good chemical spillage resistance.
Product is according to European Standard EN 13813:2002 Screed materials and floor screeds - Screed materials - Properties and Requirements.
It is a formulation of Bayer Germany and the resins are imported from Bayer.
Surfaces must be free from loose dust, debris and other contaminants. Any oil or grease deposits can be removed by a hot detergent wash with a suitable cleaner such as Uniclean, available from Frinics.
Any laitance or ingrained oil and grease will require mechanical removal by using grid blasting machine. Dust must be removed by vacuum machine before application of the product. Damage to substrate or incorrect falls should be rectified using Unibond screed before applying the Unithane W/D system.
Concrete Substrate must be strong, stable and sound with a minimum compressive strength 25N/mm2.
For application on previous flooring please contact Frinics Technical services for specific advice.
Unithane W/D is supplied in a two part system, comprising of a primer and topcoat.
Primer – One part product. Mix thoroughly
Top Coat – Two component product with base and hardener. The pigmented base must be thoroughly stirred and agitated to disperse sedimentation and achieve consistency of colour. The hardener should then be added to the base component and mixed thoroughly. Take care to minimize foaming. Allow to stand for 5 minutes before application onto prepared concrete.
Apply a sufficient thickness of the primer and the topcoat using a roller suitable for use with waterborne systems or airless spray to achieve an even substantial coat of the surface area in a sufficient thickness. When applied by roller to very rough substrates, care must be taken to avoid the formation of puddles in which excessively high wet film thicknesses occur. Water can become encapsulated in the film, which under certain circumstances can result in flaws. For general use 1 coat primer and 2 coats of paint is recommended.
The Unithane W/D coatings are suitable for sealing concrete and screed surfaces as well as synthetic resin coatings in indoor applications. Exterior application is also possible. Interfaces should be touched as soon as possible, otherwise roller marks bay become visible. The overcoating window must be observed. Has excellent ability to withstand splashes and spillages of a wide diversity of corrosive chemicals. A slip resistant finish is also available by sprinkling special sand into the surface.
Unithane produces a hard elastic coating and therefore it is eminently suitable for use in a wide diversity of industries which includes food and beverages, chemical processing, pharmaceuticals, and engineering, etc., whilst it’s outstanding dustproofing properties makes it invaluable for warehouse, garages, car parks and general factory areas.
It is ideal for use in areas where solvents are not permitted and in confined spaces where ventilation may be inadequate.
