illbruckmaking it perfect. Description SP540 is a one-part, non-sagging, elastic sealant based on hybrid-polymers. SP540 couples the processing advantages of a one-part sealant and a curing system that is very fast for such products. The time for film formation is approximately 35 to 40 minutes. During and after curing, SP540 is chemically neutral, and low odour. After total curing the product is permanently elastic while still maintaining a high mechanical strength. SP540 shows a good resistance to UV light, weather and ageing. The product is free of isocyanates and silicone.

For full recommendation, refer to safety data sheet. Surface Preparation • Joint faces should be clean of dust and free from substances likely to impair adhesion. • Loose friable material must be removed and arrises made good. Remove loose particles on concrete and plaster joints using a brush. • Metal surfaces should be degreased with solvent. • For a neat finish use masking tape for the joint edges. • Depending on the substrate AT115 and AT200 cleaners are available. • Clean powder coated surfaces with AT115. • It is recommended that preliminary tests are carried out. Usage / Purpose SP540 is an elastic hybrid sealant for floor joints in pedestrian walkways, warehouses, parking areas. SP540 can be used in both indoor and outdoor applications. Key Benefits • Isocyanate & silicone free • Fast curing • Fast tack-free time • Permanent elasticity • High mechanical strength and good abrasion resistance • Excellent resistance to weathering, ageing and UV exposure

Floor Joint Sealant illbruck making it perfect. Joint Backing • If necessary to achieve the optimum joint cross section back fill the joint with closed cell polyethylene backer rods. Pre-Treating the Adhesion Surfaces • Perform preliminary tests on critical and unknown surfaces in any case. • See adhesion table below for potentially necessary pretreatment according to our experience. Application • Apply SP540 into the joint ensuring it is in full contact with the sides of the joint and avoid air entrapment. • Use a compatible tooling agent to smooth the joint surface. • If masking tape has been...
