Polycraft Concrete Release Agent - 500ml

Product Information

Silicone-based compounds leave a very thin film that acts as a releasing agent on top of the surface. Water-based release agents made from plant-based ingredients won’t stain concrete. It will, however, need heavy spraying totaling two or three coats of vegetable oil to be effective. Reactive Release Agents Concrete Type oil is a combination of light-colored mineral oils (not to discolor concrete) and special release agents that react with the concrete to form a shield that stops concrete from adhering to either wood or metal forms.

Use a bonding adhesive to increase concrete-to-other-substance adhesion. After preparing the surface, apply your bonding agent with a brush, broom, roller, or garden sprayer. Depending on the type, it resists moisture and traffic wear. Any release agent works. Blends include linseed oil, paraffin, mineral oil, and oil-based emulsion. Whatever you apply must penetrate the wood and leave a smooth film to protect it from concrete. Oil-based release agents won’t work on steel. The fact that we can provide eco-friendly, alternative waterbased products, as concrete release agents for almost all applications clearly displays and proves that quality, efficiency and environmental awareness can be reconciled. At Ecoratio we attach great importance to the well-being of people and the environment. We believe it is important that the user of our products is not at risk. Mainly vegetable oils and label-free raw materials are used for the production of our release agents. The products of Ecoratio are non-flammable and odor-neutral.Different molds call for different release agents; some are oil-based while others are water-soluble or solvent-based. It all comes down to what kind of material you’re working with; these things act differently with certain surfaces. How to Building Construction Process Step by Step – Follow 26 Step for Building Construction Process Examine the wood to ensure that all materials are coated by lard or a shortening coating prior to pouring concrete. Most kitchens contain vegetable oil. It must permeate the wood and leave a film on its surface; therefore, you may need a lot. But it’s the greenest option. Barrier-type agents (examples include diesel oil, wax, and silicone) create a barrier between the form and the concrete. These are not recommended for architectural concrete, because they can cause stains, surface air voids, and problems with form removal in very cold or very hot weather; they also may prevent subsequent adhesion of coatings to the hardened concrete. While diesel oil was once commonly used, it’s now prohibited because the associated volatile organic content (VOC) emissions contribute to smog. (Note: In the United States, form release agents have to meet federal VOC limits of 450 g/L [3.8 lb/gal.] and may have to meet more restrictive limits of 250 g/L [2.2 lb/gal.] in some states.)

Concrete release agents consist of a base fluid in which the required additives are dissolved. This base fluid can be mineral oil with and without de-aromatised white spirit, ester/vegetable oil or, in the case of emulsions, water. Fatty acids and/or esters are usually used as separating substances. What Is a Release Agent for Concrete?For reasons of health and safety at work and environmental hygiene, water-based products are increasingly used in stationary production plants. Emulsions which are utilised as concrete release agents are the latest product generation. The emulsions can be used in precast plants on all standard formwork such as steel formwork, plastic-coated wooden formwork etc. Compared with solvent-based concrete release agents, emulsions have distinct advantages thanks to their handling and application. Emulsions from the SOK AQUA range are non-flammable and virtually odourless during spraying. The effects of the SOK AQUA products in terms of concrete technology correspond in most cases to the concrete release agents containing solvents. The user therefore obtains flawless exposed concrete surfaces that are free of pores, shrink holes and stains. The concrete surfaces are bright and smooth. Furthermore, the formwork can be easily cleaned without too much effort.
