Key products include weatherproof and waterproof silicone sealants for glazing and curtain walls, fire-rated MS sealants (e.g. FR50), tile and stone epoxy grout sealers (e.g. Antas 651), and kitchen & bathroom silicone sealants. These products are engineered and rigorously tested for Australian conditions – from façades and glazing to roofing, windows, kitchens and bathrooms.

Quality is paramount. Antas products conform to international and Australian standards (ISO, ASTM, AS). For example, our structural silicone sealants meet AS 4666 requirements and fire-rated sealants are tested to AS 1530.4.
