Arbosil HM is a One-part High Modulus Acetoxy Cure Silicone Sealant, which cures rapidly on exposure to moisture vapour to form a resilient elastic silicone rubber. This product contains a fungicide to make it resistant to fungus and mildew. Arbosil HM bonds well to acrylic, ceramic, metal, glass and laminate surfaces and will not discolour during its service life whilst maintaining good elasticity.

This product is recommended for the sealing around all types of sanitary fittings, including baths, showers, urinals, sinks, and washbasins in domestic and commercial locations. It is suitable for use in areas of high humidity. It can be used to seal around laminates and worktops. Suitable for both interior and exterior use. Use for sealing of aluminium sheets and components. Use as an adhesive to bond PVC trims.
NB: It is not recommended for overpainting or use against most metal surfaces, particularly soft metals like brass or lead, and is not for use against natural stone. (Contact Adshead Ratcliffe Technical Services for advice on which product to use against these substrates).
The joint surfaces must be clean, dry and free from all contamination and any loose materials. The surfaces should be degreased using the appropriate Arbo Cleaner. Primers may be required on some substrates. It is recommended that Adshead Ratcliffe Technical Services Department should be consulted and advice obtained with regard to the choice of primer for specific purposes.
Where applicable, appropriate joint filler, e.g. closed cell polyethylene foam, should be used to provide the correct joint depth.
Arbosil HM is supplied in cartridges and can be applied into the joint using an Arbo Caulking Gun. All joint preparation, priming, and sealant application should be carried out in accordance with BS 8000 Part 16, the British Standard for the sealing of joints in buildings using sealants.
