Sika SikaCor 6630 systemTopcoat is a low-solvent, oxidative drying high-build coating with active corrosion protection pigments based on modified synthetic resin combination. Suitable as a system alongside Sika SikaCor 6630 System Primer.
Sikacor Icosit 6630 is a one coat polyurethane paint system that can be applied directly to new and weather galvanised steel, especially suited for application to Steel and Street Furniture. This system is highly versatile and can be used directly onto steel and galvanised steel, whether it is new or weathered. It can also be used to overcoat previously painted steel. Offers a life expectancy in excess of 15 years to first maintenance in ISO 12944 Part 5.
The Sikacor 6630 System (Primer and Topcoat) is best used for providing weather resistance to rural, industrial and marine atmospheres. However, it also works excellently well on all kinds of street furniture, including lighting columns, pipelines, bridges, lattice, masts and the outside protection of silos. Sika 6630 is hard wearing and weather resistance making it extremely long lasting as it needs to be.
In case of manual de-rusting:
Galvanized surfaces, stainless steel, copper, aluminium, hard PVC and timber:
In case of aggressive industrial atmosphere or highly polluted surfaces (e.g. by chlorides, sulphates, nitrates etc.), Blast cleaning to Sa 2 ½ according to EN ISO 12944, part 4. Free from dirt, oil and grease. In case of lower exposure as e.g. in rural atmosphere or indoors, manual surface preparation (power tool cleaning) to St 2 is acceptable.
Galvanizing, stainless steel, copper, aluminium, hard PVC:
Free from dirt, oil, grease and corrosion products.
In case of well adhering coating systems, careful cleaning (e.g. by water jetting) is sufficient. Loose particles must be removed, defective areas to be de-rusted to
surface degree PSa 2 ½, PMa or PSt 2 and primed with SikaCor®-6630 Primer.
For contaminated and weathered surfaces e.g. galvanized or primed areas we recommend to clean with SikaCor® Wash.
The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry
film thickness is easily achieved by airless spray. Adding solvents reduces the sag resistance and the dry film thickness. In case of application by roller or brush,
additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc.
Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.
