The product can be stored at least 12 months in its original unopened packaging, if kept dry and cool (not under -15°C). Avoid storage under strong sunshine.

Fields of application

weber.tec 780 is used as release agent designed as bondbreaker between formwork and freshly cast concrete. Suitable for absorbent and non-absorbent formwork: timber, resin-bonded plywood, steel, aluminium and fiberglass. Also for cleaning and care of building machines and equipment.

Produkteigenschaften

• bio-degradable: no detrimental effect to the soil and the water
• good separating effect of formwork (chemical and physical release action)
• high self-cleaning effect of formwork
• rainproof, wood-preserving and corrosion-preventing
• very economical
• easy spraying, even at low temperatures
• temperature resistance up to +80°C: hence suitable for heated formworks
• does not reduce the porosity of released concrete surfaces
• provides very good exposed concrete properties; neither stains nor contaminates released concrete surfaces
• highly stable during placement and vibration of concrete
• not toxic: neither irritates nor causes skin sensibilization

General notes

• Do not use on rubber-coated formworks.
• In the case of textured formwork adjust the dosage so that the separating agent does not accumulate locally.
• When observing the specified consumption, the product does not leave any discoloration or stains on the concrete and does not impair the adhesion of subsequent coatings such as paints and renders.

Special notes

• A wood-preserving additive makes timber formwork water-repellent, thus protecting the shutter boards from swelling, cracking and rotting and considerably increasing their durability.
• An anti-rust additive inhibits the rusting of steel formwork and thus prevents the formation of rust spots on the concrete surface.
• Upon removal of the formwork an improved wettability of the surface provides the optimum adhesion of renders, paints, adhesives or any other coatings and prevents damage due to reduced bonding strength as caused in particular by release agents containing oil or wax.
• The product is not soluble in water; hence, the applied film is weather-resistant. Even after exposure to rain or dew, it will not cause any danger of slipping when walking on the formwork surfaces.
• It has self-cleaning properties on steel formwork, which allows to minimize or even completely dispense with any cleaning work.
