It withstands UV, ozone, saltwater immersion, and extreme temperatures while being safe for aquatic life. Suitable for glass, metals, plastics, and timber, it offers versatile, durable bonding and sealing with a smooth, non-slumping paste formula. ## Description HA6 is a high quality, non‐shrinking, marine quality, automotive silicone sealant. Surpasses the requirements of EN15651‐1,2:2012. Uses HA6 is unaffected by UV, ozone, salt water immersion and extremes of temperature and is non-slumping in paste form. HA6 contains no fungicides or oils which may leach into water and is therefore recommended for bonding, bedding and sealing glass in aquarium construction. HA6 is also recommended for the manufacture of in-situ gaskets and seals for pumps and pipework to prevent water ingression and as a dust and weatherproofing seal for cabinets in dirty environments or external applications. It is ideal for use on: glass; ceramics; anodised aluminium; primed metals and timber and many plastics. Preparation Ensure all surfaces are clean, dry and free from grease, oil or any other contaminants that may hinder adhesion. Prime porous surfaces and metals other than anodised aluminium or stainless steel for optimum adhesion. Application Apply using a standard sealant gun with the nozzle cut at an angle of 45°, and to an opening slightly larger than the joint to be sealed. For sealing and bedding apply in the normal fashion and tool to a smooth finish one or two minutes after gunning. As an adhesive bring the two surfaces together before skinning commences and do not stress the joint before the silicone has developed strength. As a gasket apply to one surface and if the joint is to be broken allow a strong skin to develop before compressing for permanent gaskets the joint can be sealed immediately. Clean away any excess with white spirit. When using in aquarium assembly please refer to separate sheet for instructions which can be supplied upon request. Limitations Not suitable for use on bitumen, asphalt, natural stone or unprimed metals. Do not use as a mirror adhesive, Do not apply at temperatures below 5C or above 30C.
