weber.tec 960

Colours:

light grey and white

Drying time:

approx. 2 days

Storage:

The product can be stored at least 12 months in its original unopened packaging, if kept dry and frost-free. Frost destroys the product. After thawing it is not allowed to use it

Fields of application

weber.tec 960 is used as decorative and reflective membrane for old bituminous substrates (roofing felts or membranes), for metallic substrates (zinc, aluminium, copper, zinc) as well as for new or old fiber cement sheets (such as Eternit, Fulgurit, Wanit). Also as protective coating for pitch roofs (minimum slope of 2%) on administration buildings, factories and stores, warehouses, exhibition halls, hospitals, schools etc. After drying, weber.tec 960 provides a watertight, vapour-permeable, extremely elastic and rubberlike membrane without seams and joints. For use outdoors.

Main features

• highly elastic (elongation at break of approx. 350% at +23 °C)
• reflects up to 70% of solar radiation and reduce temperature of room in summer
• permeable to water vapour
• resistant to sparkling fire (B 2 according to DIN 4102, part 7)
• resistant ageing and UV radiation, to great variations in temperature (approx. -30 °C to +100 °C), diluted acids, alkalis, and aggressive industrial gases
• reflects up to 70% of solar radiation and reduce temperature of room in summer
• solvent-free
• for use outdoors

General notes

• All characteristics mentioned in this data sheet are based on a temperature of +23 °C, without draught and a relative humidity of rate 50% on +20 °C.
• Higher temperatures and lower humidity rates accelerate, lower temperatures and higher humidity rates slow down the drying process.
• The light colors of weber.tec 960 reflect the UV radiation up to 70% and cools the room temperatures down in summer.
• At low temperatures and/or high humidity rates apply the material in several thin coats, in order to provide a thorough drying of the whole membrane (complete film formation) and consequently to avoid a reduced elasticity of the dry film as well as crack formation. Applications in thicker coats will result in a substantial much longer drying time.
• Flat roofs should have a slope of minimum 2%.
• Prior to application treat all cracks in an appropriate way.
• In case of spray application, use airless guns and air-assisted pumps. A dilution up to 5% water is allowed. A higher dilution will lead to sedimentation and is therefore not suitable for spraying.

Special notes

• Limits of use: do not use weber.tec 960 on roof areas with permanently standing water, polyurethane-based rigid spray-foam roofs, bitumen roof surfaces which are younger than 12 months, bitumen felts which are covered with gravel or pebble dash and bitumen felts with porous inserted textile layer.
• Fiber cement sheets must be asbestos-free.
• Do not add foreign products during application.
