APPLICABLE STANDARDS: JC/T884-2001
One part, neutral curing silicone sealant with excellent primerless adhesion on all types of Aluminum panel and Aluminum Composite Panel, widely used for weather sealing in all types of Aluminum Cladding and ACP Curtain Wall, gap sealing for concrete, plastics and alloys. Excellent weatherproof performance. Sino-bond 838 is extruded from tube with sealant gun when used, and it absorbs the moisture in the air, and then cures to elastomer capable of maintaining a seal effectively.
Weather sealing in all types of Aluminum Cladding and ACP Curtain Wall, gap sealing for concrete, plastics and alloys.
LIMITATIONS:
Do not use for structural glazing. Not recommended for building materials that bleed oils, plasticizers, or solvents–materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes. Not recommended for use in totally confined spaces as the sealant requires atmospheric moisture for cure. Not recommended for continuous water immersion applications. Not recommended for use on frost-laden or wet surfaces. Not recommended for places where painting of the sealant is required, as the paint film may crack and peel. Do not apply at temperatures below 4°C or above 40°C.
