WEICON Silicone A is solvent-free, acetoxy-curing, strong, permanently elastic, resistant to ageing and chemicals, temperature-resistant up to +180 °C (+356 °F), extremely elastic (breaking elongation >700%) and can be used universally. Silicone A adheres very well to steel, aluminium, glass, ceramics, and many other materials. Silicone A can be used in machine and system construction, ventilation and air conditioning systems, in the energy and electrical industry, in exhibition construction and shopfitting and in many other industrial applications.
LOCTITE® SI 5130 is a white, thixotropic, room temperature-cure, acetoxy silicone paste designed for superior bonding and sealing properties to most surfaces (not recommended for concrete). It resists ageing, weathering and thermal cycling without hardening, shrinking or cracking. It is formulated to withstand extreme temperature cycling, UV light and ozone.
