Product LK-RX22D T245 preliminary used for the water-resistant application, including – As a water repellent additive for gypsum boards (0.05%–0.2% based on solids)
As a surface coating on hydrophilic powders (e.g., calcium carbonate) to prevent clumping due to moisture absorption.
As a water-repellent treatment for textiles, wood, and particle boards as an intermediate in formulations for coatings or admixtures.
How is methyl hydrogen silicone fluid product LK-RX22D T245 useful in gypsum board water-repellent applications?
LK-RX22D T245 enhances the water resistance of gypsum boards by acting as a hydrophobic additive. When added at 0.05%–0.2% of the solids weight, it significantly reduces moisture absorption, improving durability and performance without affecting board strength or processing. This product added during the mixing of gypsum and water in mixing tank.
Can the methyl hydrogen silicone fluid LK-RX22D T245 be diluted?
LK-RX22D T245 can be easily diluted using common solvents (neutral pH) , allowing flexibility in formulation and ease of application across various substrates. But for the admixture application recommended to use as such. Product LK-RX 22D T245 is not soluble in water.
How can water repellent methyl hydrogen silicone product LK-RX22D T245 be applied in coating applications?
Water repellent LK-RX22D T245 can be applied as a surface coating either directly or in diluted form. It can be sprayed or brushed onto the substrate and may be used alone or with suitable catalysts to accelerate curing. For best results, maintain the pH between 5-7 during application.
