Sika® Sigunit® SA 540 (formerly MasterRoc® SA 540) | MCT CHEMICALS | MASTER BUILDER SOLUTIONS

Usage of MRoc SA 540:

1. Bonding Agent: MRoc SA 540 is widely used as a bonding agent in concrete, mortar, and plaster applications. It enhances the adhesion between different substrates, ensuring superior bonding strength for surfaces that require durability and long-term performance.
2. Tile and Stone Adhesives: It is commonly added to tile adhesives to increase the bond strength between tiles and various surfaces like concrete, ceramic, and stone, providing enhanced holding power even in high-moisture environments.
3. Waterproofing: MRoc SA 540 is used in the formulation of waterproof coatings and sealants to improve their moisture resistance and flexibility, ensuring that surfaces remain dry and durable under challenging environmental conditions.
4. Repair Mortars: In the production of repair mortars, MRoc SA 540 improves adhesion and crack resistance, allowing for more effective and long-lasting repairs in both indoor and outdoor environments.
5. Coatings and Surface Treatments: It is often incorporated into coatings for floors, walls, and other surfaces, providing enhanced durability, resistance to wear, and better overall performance.

Application Coverage:

• Concrete and Mortar: The typical dosage of MRoc SA 540 is between 1% to 5% by weight of the total cement content, depending on the desired performance characteristics. For highly demanding applications, higher dosages may be used.
• Tile Adhesive: In tile adhesive formulations, MRoc SA 540 is used to ensure superior bonding strength and flexibility, making it ideal for areas exposed to moisture, such as bathrooms and kitchens.
• Waterproofing and Sealants: For waterproofing applications, MRoc SA 540 is mixed into coatings and sealants to enhance their resistance to water penetration and weathering. Coverage rates will depend on the surface area being treated and the type of application.
• Precast and Repair Applications: MRoc SA 540 is used in precast concrete elements and repair mortars to enhance the mechanical properties, adhesion, and durability of the final product.
