A New Breakthrough In Fast-Drying Silica Sol Taiyuan Simis

The fast-drying silica sol has achieved a breakthrough in enabling a single product to have both surface and back layer functions, increasing the drying efficiency by over 50% while reducing defect rates and production costs

In the field of casting silica sol, the breakthrough of fast-drying silica sol lies in achieving both surface and back layer functions through a single product, significantly enhancing production efficiency and reducing costs.

The differences between traditional surface layer and back layer silica sol

Surface layer silica sol: It features high viscosity, high curing temperature, high precision and easy peeling, and is mainly used for manufacturing parts with high precision and high surface quality requirements.

Back layer silica sol: It features low viscosity, low curing temperature, enhanced structure and cost reduction, and is mainly used for manufacturing large and complex-structured castings.

Single product achieving surface layer and back layer functions: Traditional surface layer and back layer silica sols have significant differences in material properties and application fields, and different products need to be used respectively. The emergence of fast-drying silica sol enables a single product to meet the requirements of both the surface layer and the back layer, simplifying the production process and enhancing production efficiency.

Fast-drying property: Fast-drying silica sol has a remarkable fast-drying property, which can form a stable coating in a short time, significantly shortening the shell-makin cycle. For instance, some fast-drying silica sol products can complete a coating in about 2 hours, which is over 50% longer than the drying time of traditional silica sol.

Improving the quality of castings: Fast-drying silica sol, by optimizing the formula and process, enhances the film-forming toughness and coating performance, and improves defects such as surface slurry cracking, casting wings, and rat tails, thereby improving the product quality of castings.

Cost reduction: As fast-drying silica sol can simultaneously meet the demands of both the surface layer and the back layer, it reduces the amount of material used and the frequency of material replacement, thereby lowering production costs.
