Certified to EN15651-1,2:2012, it guarantees professional-grade durability and safety for aquatic environments, making it the go-to choice for managers demanding reliability and eco-conscious performance. ## 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. Colour HA6 comes in 4 colours: white, translucent, black and grey. Container Size 310ml plastic cartridge.

Price reflects the quality of this silicone delivered on time ### ⭐⭐⭐⭐⭐ Silicone sealant *by M***D on 27 March 2026* Great product, loads of uses mine was to seal a cracked toilet cistern ! I am sure it’s possible uses are endless. ### ⭐⭐⭐⭐ Did the job although very strong some, *by C***P on 9 December 2025* Did the job nicely for building a background for my crested gecko bio active tank. Only fault is it has an extremely strong smell to begin with and it’s still slightly lingering after a couple weeks so not yet put my gecko into the tank until it’s completely gone. Substrate stuck to it really well and it seems to be holding together. ## Frequently Bought Together - BOND IT CLEAR HA6 RTV Silicone Sealant Marine Aquarium Safe Water Fish Tank Adhesive - ProDec MG11ES Extra Strong Skeleton Caulking Gun, Sealants, Silicones, Adhesives - Professional Heavy Duty Applicator Suitable for High Viscosity Products,Red,400ml and 310ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/47965123-bond-it-clear-ha6-rtv-aquarium-silicone-seal](https://www.desertcart.us/products/47965123-bond-it-clear-ha6-rtv-aquarium-silicone-seal) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
