Types of Silicone Sealants

Neutral Cure Silicone

Doric’s neutral cure silicone is the professional standard for glazing and façade applications. Its low-odour, alkoxy-based formulation ensures non-corrosive adhesion on glass, coated steel, and aluminium. Ideal for window and door sealing where longevity and finish quality are critical.

Glazing Silicone Sealant

Our glazing silicone sealant offers strong adhesion and flexible movement capability. It remains elastic after curing, maintaining tight, weatherproof joints under thermal expansion, pressure, and wind load.

Weatherproof Silicone

Built for exposed applications, Doric’s weatherproof silicone resists UV degradation and water ingress across façades, skylights, and curtain wall systems. It retains adhesion through heat cycles and ensures lasting durability in coastal or high-sun environments.

Sanitary and Mould Resistant Silicone

Doric’s sanitary silicone sealant delivers superior waterproofing and mould resistance for wet areas. The anti-fungal additive ensures a hygienic, clean finish for bathrooms, laundries, and kitchens.

High Temperature Silicone

Our high temperature silicone withstands heat up to 250°C, maintaining elasticity and adhesion in industrial, mechanical, or equipment environments.
