WACKER® 130 - GLASS AND GLAZING (German Technology)
WACKER® 130 is a one-part, acid-curing, low-modulus silicone sealant for glazing and industrial applications.
WACKER® 130 cures at room temperature under the action of atmospheric moisture to give a permanently flexible silicone rubber.
特性
• Non-sag
• Ready gunnability at low (+5°C) and high (+40°C) temperatures
• Flexible at low (-40°C) and high temperatures (+100°C)
• Rapid crosslinking: quickly becomes tack-free
• Available in a wide range of colors
• Good tooling properties for professional use
Application
• Sealing of connecting and expansion joints in indoor
• Applications and for bonding and mending tasks.
Restrictions on use
WACKER ®130 should not be used on substrates such as marble, concrete, fibrous cement and mortar, as the product releases acetic acid during vulcanization.
WACKER ® 130 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.
WACKER ® 130 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.
WACKER ® 130 is not recommended for sealing of aquaria.
WACKER ® 130 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.
WACKER® 130 is not recommended for structural glazing bonding.
Preparation
The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material, dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and a clean, lint-free, cotton cloth. Wipe dry immediately with another such cloth before the solvent evaporates from the surface.
Adhesion
WACKER® 130 exhibits excellent primerless adhesion to most non-porous siliceous material, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker; impregnated, varnished or painted wood; and some plastics.
Users must carry out their own tests due to the great variety of substances.
The adhesion can be improved in many cases by pretreatment of the substrates with a primer.
If adhesion difficulties arise please contact our technical service.
包装
WACKER® 130 is usually supplied in standard size cartridges that fit all standard caulking guns.
储存
The best use date of each batch is shown on product label.
If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
