## Overview

BOND IT CLEAR HA6 is a premium RTV silicone sealant designed for marine and aquarium use, offering superior waterproofing and UV resistance. It bonds a wide range of materials without shrinking or slumping, ensuring durable, chemical-safe seals ideal for aquatic environments and demanding outdoor applications.

## 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. Shelf

Review: Works great - Used this to build my tank. Never used silicone before but this was very easy. Waterproof after 1 application. Granted I haven't tried to break it but seems 100% stable. Very strong smell but it goes away after a few days

### ⭐⭐⭐⭐ Holds well, poor instructions.
*by O***S on 4 August 2025*

I bought this to seal a crack in my aquarium and fix a piece of glass over it. The smell is acidic and very strong. I suggest mask and eye protection. A gun is needed to apply the seal and it flows out ok, so easy to apply. There are no instructions fot curing time on the tube. My aquarium leaked at first test after 24hrs. I looked online and found out curing is approximately 1mm sealant = 24hrs curing. So i had about 5mm of sealant and waiting 5 days. Also, I read tbat sealant gives off some sort of acidic layer when curing, so I rinsed it before adding water and fish. My aquarium was fine when I tested it the second round. The quality is fine, but I had to apply almost the whole tube to get a good seal. It was a huge crack, top to bottom on a 70 ltr aquarium. It is holding well that I have stopped checking if it's leaking. 4 stars because curing time should be included in the instructions.
