INGADA™ SR-35L Low-Modulus Weatherproof Silicone Sealant – Flexible Joint
Maximum Movement (±35%) for Sensitive Stone and Façade Cladding
-
The Problem: Big joints in natural stone façades require huge movement, but standard sealants are too “stiff” and pull the stone away.
-
The SR-35L Solution: “The Architect’s Soft Touch.” Finally, a sealant that offers extreme movement without the destructive stress. SR-35L protects your high-end stone and metal cladding with a seal that’s as flexible as it is strong.

Q:When should I choose SR-35L over a standard modulus sealant?
A：SR-35L should be chosen for joints where the substrate is sensitive to stress or when sealing cladding systems that require a gentle yet flexible bond.
Q:Is SR-35L safe for light-colored natural stone?
A：Yes. Its non-staining, white-oil-free formula prevents migration and staining on porous substrates like natural stone.
Q:What is the movement rating for SR-35L?
A：It is a Class 35 sealant, capable of accommodating ±35% joint movement.
Q:How does it perform in cold weather applications?
A：It can be applied in temperatures as low as 0°C, making it suitable for year-round construction in various climates.
Q:How fast does it form a skin?
A：The sealant typically forms a skin within 30 to 90 minutes, with a full cure occurring within 24 to 48 hours.
