These products are based on block PU polymers so they are easy to work with, being non-sensitive to moisture during cure.
Features:
• NOT SENSITIVE TO MOISTURE DURING CURE.
• Easy to mix and apply.
• Suitable for sewerage and water retaining structures in place of polysulfide sealants.
• Up to 100% elongation with full recovery at 25°C.
• Excellent oil, ozone and chemical resistance.
• Suitable for use without priming on a wide variety of substrates.
• May be used on trafficable surfaces.
• The product is formulated to closely match the requirements of SABS 1077-1984, although it is not Mark-bearing.
• Not based on MDI-isocyanate curing systems, so not water sensitive.Jayco M974J Hi Duty Polysulphide Coal Tar Sealant
Jayco M974J Hi Duty Polysulphide Coal Tar Sealant is a cold applied two part elastomeric sealant, designed for cost effectiveness and chemical resistance for in joints of concrete paved areas, under all climatic conditions.
The highly elastomeric nature of cured M974J provides the extra capacity to accommodate erratic large movements common in paving joint applications with far less risk of failure than most other systems.
Jayco M974J is highly resistant to fuel, oil and hydraulic fluid spillage, will not harden in cold weather nor become excessively soft or pick up in hot conditions. The sealant will outperform conventional polysulphide or polyurethane sealants in most paving applications.
Features:
• Performance unaffected by climatic temperature extremes
• High movement accommodations: factor butt-joints 25%.
• Excellent ozone, oil and chemical resistance.
• Bonds to concrete and pitch based substrates i.e. joints previously sealed with pitch-based hot paved sealants.
• Cold applied self levelling.
• Tack-free within 12 hours at 25°C, Shore A 12 . 18 after 7 days cure.
• Fungus and mould resistant.
• Complies with requirements of BS 5212 -1975.Jayco M220 Acrylic Sealer
