DESCRIPTION
Unisil SP 65 is a three-component granule, consisting of a powder carrier, an encapsulant, and a finely dispersed active silicone agent. It is also a silicone-based water-repellent agent in powder form designed for gypsum-based dry mixes, blocks, putties, plasters, grouting and other materials.
FEATURES
Unisil SP 65 was developed to impart the performance of a liquid silicon-based hydrophobic material in dry delivery systems. It is a water-repellent additive in powder form that allows for achieving very high water-repellence values. Once the correct dosage is achieved, the additive makes the products water-repellent. The encapsulant provides storage stability in the powdered composition and the release of the active ingredient upon the addition of water. Unisil SP 65 provides excellent dispersibility in water and will provide instant hydrophobicity upon cure.
APPLICATIONS
The main application area of Unisil SP 65 is a hydrophobic additive in the production of moisture-resistant gypsum-based dry mixes, putties, plasters, grouting, blocks, decorative elements, and other gypsum products. This product can find uses in many application areas where the protection of the substrate from liquid water ingress is a critical issue. In existing and developing formulations of dry mixes based on gypsum, it is required to create or improve moisture-repellent properties. It acts as a barrier to the capillary movement of liquid water in gypsum-based grouts, joint fillers, mortar, EIFS, stucco, and façade-rendering applications.
STORAGE
Store in a sealed original container at temperatures from 0°С to +50°С. Store in a cool, dry, well-ventilated place, away from areas with a risk of fire and contamination with strong oxidants, alkalis and inorganic acids. Protected from moisture and direct sunlight. Guaranteed shelf life is 12 months. Storage over the date specified on the label does not necessarily mean the product is unusable. Please check the properties of the product before use.
