HA6 is a high quality, non-shrinking, marine quality, automotive silicone sealant that surpasses the requirements of EN15651-1,2:2012. It 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 that may leach into water, making it recommended for bonding, bedding, and sealing glass in aquarium construction. It is also recommended for manufacturing in-situ gaskets and seals for pumps and pipework to prevent water ingress 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, timber, and many plastics. Preparation involves ensuring all surfaces are clean, dry, and free from grease, oil, or other contaminants that may hinder adhesion. Priming porous surfaces and metals other than anodised aluminium or stainless steel is recommended for optimum adhesion. Application is done using a standard sealant gun with the nozzle cut at a 45° angle, 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 instructions. 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 5°C or above 30°C. HA6 comes in 4 colours: white, translucent, black, and grey. Container Size: 310ml plastic cartridge.
