Sikasil® SL 189
(former MSeal SL 189)
Ultra-low modulus silicone sealant for concrete and asphalt substrates
Sikasil® SL 189 is a high performance, one-part, moisture curing silicone construction sealant. The Product offers ultra-low modulus, fuel and UV resistant, elastomeric seal. The ultra-low modulus minimises the strain on the asphaltic joint face, which is necessary due to the low tensile strength of asphaltic paving materials.
- Ready for use
- Low stress on substrate due to the low modulus of the sealant
- No primer required
- Very good durability
- Adapts to joint width and alignment irregularities
- Wide service temperature range
