Description Geocel HM Silicone Sealant is a one-part sealant, which has been specifically developed for use by the sealant contractor. It has good adhesion to a range of nonporous substrates including glass, aluminum and painted wood. Geocel HM Silicone Sealant is suitable for use in sanitary applications
Benefits • Specially developed for use by sealant contractors • High modulus, high elasticity • Fungus and mildew resistant • Conforms to ISO11600 • Resistant to ozone, ultra-violet radiation and temperature extremes.
APPLICATIONS
Ensure that surfaces to be sealed are clean, dry, sound and free from frost. Clean all joints of release agents, water repellents, laitance, dust, dirt, old sealants and other contaminants, which could impair adhesion. Non-porous surfaces should be cleaned and degreased by wiping with a suitable solvent such as Geocel Surface Cleaner on an oil and lint-free cloth before application of the sealant. Porous substrates should be mechanically cleaned using a steel brush, sanding disc or any similar means. Note: When using any solvent, always provide adequate ventilation. Avoid heat, sparks and open flames. Use solvent resistant gloves. Observe and follow all precautions listed on solvent container label.
JOINT DESIGN When designing joints using Geocel HM, the minimum width should be 6mm. For joints between 6mm-12mm wide, a seal depth of 6mm is required. For joints above 12mm wide, a width to depth ratio of 2:1 should be used up to a maximum depth of 12mm. In situations where fillet joints are needed, a minimum of 6mm sealant bite to each substrate is recommended.
