Key Features
Colour Matched (RAL 7038): Specifically pigmented to match Agate Grey window and door profiles, ensuring the perimeter seal blends perfectly with the frame.

Low Modulus Neutral Cure: Offers high elasticity and permanent flexibility, allowing it to absorb movement between the frame and the building structure without cracking.

Premium Tooling Properties: Renowned for its buttery consistency, making it exceptionally easy to apply and smooth off for a clean, architectural finish.

Non-Corrosive Formula: As a neutral oxime silicone, it is safe for use on sensitive metals and will not affect the edge seals of insulated glass units.

High Weather Resistance: Fully UV-stable and waterproof, designed to withstand the harshest external conditions without shrinking, fading, or losing adhesion.
