Joint Design
- The joint width must be designed to suit the movement capability of then sealant.
- In general the joint width must be greater than 10 mm and less than 35 mm.
- A width to depth ratio of 2 : 1 must be maintained for joints over 12mm wide with a minimum depth of 8mm.
- All joints must be properly designed and dimensioned by the specifier and the main contractor in accordance with the relevant standards.
- Backing: Depending on application closed cell, polyethylene foam backing
rods or open cell foam backing rod must be used.
Service Temperature
- +5 °C to +40 °C
Ambient Air Temperature
- >5ºC – <35ºC
Substrate Temperature
- >5ºC – <35ºC
Curing Rate
- ~3-4mm per 24 hours (+23°c & 50% relative humidity)
SkinningTime
- ~40 minutes (+23°c & 50% relative humidity)
IMPORTANT CONSIDERATIONS
- • Elastic sealants may not be over painted with rigid or less flexible coatings.
- Compatibility testing of proposed coatings must be undertaken to ensure suitability.
- If there is no history of a particular coating/paint being applied over cured Sikaflex® Fillet for a period of six months or more, an overpaintability test should be made to determine:
- That the paint dries properly within the expected tim frame.
- That if the paint film dries satisfactorily it is not subsequently softened and/or stained where it comes int contact with the Sikaflex® Fillet when exposed to the heat of the sun.
- That the adhesion of the paint/coating is satisfactory.
- Colour deviations may occur due to exposure to chemicals, high temperatures, UV-radiation. However a change in colour will not adversely influence the technical performance or the durability of the product.
- Do not use Sikaflex® Fillet as a glass sealer, on bituminous substrates, natural rubber, EPDM rubber or on building materials which might bleed oils, plasticizers or solvents which could attack the sealant.
- Sikaflex® Fillet should be used with care resealing joints that were previously filled with silicone seal-ant. Consult our Technical Department.
- Do not use Sikaflex® Fillet to seal swimming pools.
- Only use in well ventilated areas.
- Do not mix with or expose uncured Sikaflex® Fillet to substances that may react with isocyanates, especially alcohols which are often components within e.g. thinners, solvents, cleaning agents and form-work releasing compounds. Such contact could interfere or prevent the cross linking curing reaction of the material.
- Epoxy resin coatings should be fully cured prior to the application of the adhesive / sealant as the un-cured amine component could inhibit the cure of polyurethane adhesives / sealants.
