Tecno-Sil 620 is a Low Modulus, one component, odourless, ready-to-use and easy to tool neutral silicone elastomer intended to produce sealing and bonding joints.
Tecno-Sil 620 has been especially formulated with professional sealant applicators in mind. It cures at room temperature in the presence of air moisture to give a flexible and strong seal with low modulus of elasticity.
Applications: Tecno-Sil 620 is intended to seal and bond joints in the construction and glazing industries, specifically for: • Traditional construction joints to accommodate expansion and maintain stability. • Light duty prefabrication including curtain walls metal covings. • Bonding of decorative panels • Perimeter seals in aluminium, wood and PVC frames. • Elastic seals in glazing applications on aluminium, wood and PVC. • Heavy duty prefabrication (terrace, wall and facade panel joints) • Ventilation ducts, piping passages, guttering
