KASTAR988 High Tack Hybrid MS polymer sealant-1763709140098628

Product Details

KASTAR 579 is a carbon-based, silicone-modified reactive resin adhesive (Type R) designed for high-demand bonding scenarios. It is especially suitable for laying large-format, low-absorption ceramic tiles, stone, and slabs, and is ideal for tile-on-tile bonding during renovation. Beyond tile applications, it bonds and reinforces various building materials (bricks, prefabricated wall panels, foamed ceramic moldings) with smooth shear walls and metal substrates, and also prevents cracking at joints of building materials. The adhesive film has excellent flexibility, freeze-thaw cycle resistance (-30℃ anti-freezing), high-temperature resistance (withstands boiling at 100℃), water resistance, aging resistance, and resistance to thermal expansion and contraction. It cures quickly, enabling load-bearing within 3 days at room temperature, and requires no treatment of tile release agents, simplifying construction.

Product Advantages

1.Ultra-High Bonding Strength: Bonding strength is several times higher than traditional cement-based tile adhesives and mortars; standard state, water immersion, and heat aging bonding strengths all reach ≥8MPa, ensuring stable bonding.

2.Flexible Construction Options: Available in slow-drying and fast-drying types to match different construction speeds. At 25℃/room temperature, the slow-drying type has an application time of about 1 hour for 6kg batches (3 hours for small thin layers), and the fast-drying type has an application time of about 30 minutes.

3.Wide Substrate Adaptability: Applicable to mortar plastering walls, smooth shear walls, smooth waterproof walls, fiber cement boards, OSB boards, iron floors, glass, and floor substrates, meeting diverse installation needs.

4.Efficient Construction: No need to deal with tile release agents; only one side of the tile or substrate needs grooving (using a suitable notched trowel based on substrate flatness), saving construction time.

Product Features

1.Strong & Stable Bonding: Forms a firm bond between tiles/slabs and substrates, with bonding strength ≥8MPa in various states (standard, water immersion, heat aging), preventing tile falling and ensuring long-term structural safety.

2.Crack Prevention & Reinforcement: When used for building material joints and reinforcement, it effectively inhibits cracking caused by thermal expansion and contraction or external forces, enhancing the overall stability of the structure.

3.Rapid Load-Bearing: Cures quickly, enabling load-bearing within 3 days at room temperature, shortening the construction period and allowing early use of the space.

4.Wide Application Effect: Suitable for indoor and outdoor large-format tile/slab laying, renovation, and building material bonding, maintaining excellent performance in different scenarios and meeting diverse construction requirements.
