In the actual use of sealant, we may encounter questions about the color of the sealant. For example, how to choose the color of building sealant, why some products have less color, how to control the color difference of sealant products, why the sealant will change color, etc. This paper answers these questions.
First, how to choose the color of building sealant?
The variety of colors in modern buildings has led to an increasing variety of architectural sealants. In order to facilitate the customers to quickly choose the color of the building sealant, Baiyun Chemical has produced a color standard color card for the building sealant. The user can directly determine the color and the corresponding color number through the standard color card.
Under normal application conditions, the three conventional color colors of black (1000), white (2000), and gray (3000) can be used to meet the requirements of use. If the customer wants the sealant to be close to the color of the substrate, you can choose a special color similar to the substrate on the swatch. If you can't find a close color, you can also send the substrate to the Baiyun Chemical to determine the special color number.
Second, why is the structural sealant and fire sealant rarely tinted?
Structural sealants are generally black, and occasionally white and gray. Why is the structural sealant rarely tinted?
The role of structural sealant is to adhere the glass to the aluminum sub-frame, and to withstand the aging of ultraviolet, ozone, moisture, etc. for a long time (more than ten years or even decades), while at the same time bearing the wind for a long time (more than ten years or even decades) Load caused by gravity, temperature, etc. Therefore, the structural sealant is used between the glass and the aluminum sub-frame, and can be seen through the glass. Generally speaking, the difference between the color of the structural sealant and the substrate does not cause a significant visual effect, and it can be said that there is no direct color to the color. Needless, no need to entangle in color. Since structural sealant plays a vital role in curtain wall safety, in order to ensure the performance of the product, we will confirm the color formula according to the color number required by the user to ensure the special color matching requirements of the structural sealant. Application security.
The color of fireproof sealant is also relatively rare. What is the reason? The function of fireproof sealant is fireproof and smokeproof. If it is used for building interlayer sealing, there is no direct demand for coloring. If the user has special needs, it needs to be color-coded. Under the premise of ensuring excellent performance, our company needs to fully confirm the color formula according to the color number required by the user, and confirm the order before placing the order. In general application, the author recommends that customers use conventional color (black, white, gray) fireproof sealant products.
