Waller & Wickham also supply other adhesives and products, here is a sample of Purfex, Helmitin 121, Rapid Balcotan 100 and Awlgrip.
Purflex Marine is a single component polyurethane sealant and adhesive that has been designed to meet a variety of needs with the marine industry. It has been specifically formulated to overcome the pistoling effects associated with deck caulking at high temperatures. Purflex Marine can be used for deck caulking operations at ambient temperatures up to 50OC.
With excellent seawater resistance, Purflex Marine is ideally suited for sealing decks, hulls, windows and potholes, as well as bedding in removable deck fittings. Purflex Marine is an excellent adhesive suitable, for most marine substrates, such as aluminium, plywood, glass, GRP and wood and can also be used for reducing vibrations.
The material cures by reaction with atmospheric moisture to form a high performance, permanently flexible sealant and adhesive. Skin and cure times are dependent upon humidity and temperature, with increased levels producing faster reaction.
Purflex Marine has been specifically formulated to offer the following characteristics.
Fast Cure
Permanently Rexible
Low Odour
Low Shrinkage
Non Corrosive
Non Staining
Excellent Seawater Resistance
Purflex Marine can be applied directly from the cartridge, using standard hand or air operated guns and is recommended fro the following typical applications:
Bonding
Hull to deck assembly (GRP)
Deck caulking
Deck to GRP Hull
Deck to aluminium
Application: Helmitin 121 is a cyanacrylate, ready to use, one component solvent free adhesive which forms bonds in seconds on a wide variety of substrates.
Helmitin 121 is especially good for bonding rubber material with each other and with metal, glass and various materials.
Special Properties:
- Helmitin 121 sets very quickly (within a few seconds).
- The bonded parts are instantly ready for further processing.
- The set adhesive bonding has a good resistance against isopropanol, gasoline, oil.
- Further resistance on request.

Danger
Cyanaocylate: Bonds skin and eyelids within seconds. Keep out of reach of children.
Instructions for Use:
- Thoroughly clean and dry both surfaces to be bonded.
- Apply adhesive to one surface only.
- Press the two surfaces together for a short time, depending on the substrates.
- The key to successful application of Helmitin 121 is the formation of a thin film of adhesive between the two surfaces.
-It can be obtained by slightly rubbing of the material.
Remarks:
Irritating to eyes, respiratory system and skin.
Safety advice:
- Do not breathe vapours.
- Avoid contact with skin and eyes.
- In case of contact with eyes, rinse immediately plenty of water and seek medical advice.
- Containers should always be kept well-closed and protected from moisture.
- Due to the high reactivity of the adhesive, a direct contact with the skin should be avoided.
- Adhesive can be removed from the skin by HELMITIN solvent 694 or by hot water.
- With eye and mouth bindings contact physician at once.

Gold Label can be applied at any time prior to launching. There is no time limit between apllication and launching which allows, if it is more convenient, to anti-foul in the Autumn and launch the boat the following Spring. Gold label is not active until fully immersed in water, so during haul out periods or prior to launching, the anti-fouling chemistry is completely inactive.
Gold labelis 100% tin free, self-polishing, multi-season anti-fouling. The more you apply the longer it lasts. There is no build upof inactive anti-foul with Gold label - as long as there is a layer on the hull, then it will be an active layer, assisting performance and providing totl anti-fouling protection.
