Neutral Silicone Sealants is a one-part, medial modulus, neutral curing sealant. It has an excellent adhesive ability to most construction materials without a primer.

 Characteristica. Can be easily used and extruded any time.b. Excellent contact change and extrusion ability, in any air temperature( -40°C to 100°C) can extrude easily.c. Excellent adhesion to stone, ceramics, concrete, and other building materials. It has no pollution to porous materials.d. Outstanding weatherproofing ability, resisting to ultraviolet ray, ozone.e. Be compatible with all kinds of silicone structural sealant. Use limitationsnot fit for structural usage. It should NOT be applied in the following conditions:a. To all materials that bleed oils, plasticizers or solvents, and green or partially sulfur zed gaskets or tapes, etc.b. In totally confined space (Silicone sealant need the water in the air to cure)c. For continuous immersion in water or below-grade applications all the year.d. To painted surfaces, may cause seal failure as the paint cracking or paint strippinge. To frost or wet surfacesf. Surface touch the food directlyg. Easily suffer mechanical clash Typical properties (for reference)The following data is for reference, is not suggested to make standard.
