Using sealant outdoors can reflect the performance

The products of sealant manufacturers have a good understanding of outdoor use. The bond is made of synthetic resin, natural resin and other dry or non-drying adhesives as the base material, together with talcum powder, carbon black and other materials as auxiliary materials. The product has the advantages of better materials such as leakage prevention, fire prevention, sound insulation, and better waterproof effect.
Choose more reliable products provided by the sealant factory. The outdoor waterproof effect is better. The adhesion and strength are also better reflected, becoming a product that many customers like. It can achieve better results in terms of reliability. The quality assurance is better, and the advantages brought by it are more prominent. There are many analogies in sealants that divide the adhesives into vulcanized and non-vulcanized types. Among the vulcanized bonds, the room temperature vulcanization type is more widely used, while the vulcanized type is rarely used. The non-vulcanized sealant has a liquid adhesive and a greasy feel. Also, the commonly used anaerobicity is added. The liquid cement can be used alone or together with the gasket. The appropriate type of liquid sealant should be selected according to the conditions of use, and attention should be paid when using it.
Pretreatment:?Remove grease, water, dust or rust from the sealing surface. When used alone, the distance between the two sealing surfaces is 0.1 mm;
Coating:?The coating thickness depends on the processing accuracy, flatness, gap size and other specific conditions of the sealing surface. Usually, the thickness of 0.06 to 0.1 mm is applied to the two sealing surfaces, respectively;
Drying:?The solvent-based liquid sealant needs to be dried. The drying time is usually 3 to 7 min, depending on the type of solvent used and the coating thickness;
Tightening:?The tightening method is the same as the gasket seal, and the sealing surface cannot moved by mistake after tightening.
Introduction to the problems of sealant manufacturers in winter fabrics
The fourth week of temperature drop by the sealant manufacturer will bring results to the sealant, that is, it hardens slowly during the application process. The curing process of the bond is a chemical reaction process. The temperature and humidity of the environment have a specific effect on the curing speed. The higher the temperature and humidity of the sealant, the faster the curing speed. Then in winter, the temperature drops sharply and the lower the humidity, the curing response of the bond will be affected. Sometimes the glue hardens. Will slow down. Generally speaking, when the temperature is lower than 15, the hardening of the structural adhesive is apparent.
The user should work in a high temperature environment, stop the small area adhesive test before use, and stop the peeling adhesion test, it is recommended that the structure sealant is cured, the adhesion is good, and the appearance is not good, and the impression is not good. It is used in a large area. It is recommended to apply the structural sealant when the ambient temperature is lower than 4
What are the uses and characteristics of waterproof sealant？
The waterproof sealant does not contain aromatic hydrocarbons and toxic solvents. It is an environmentally friendly product. It has good adhesion to the surface of concrete, metal, wood, stone, plastic steel and sunshine board. Waterproof sealant is used for sealing between doors and windows, awning walls, steel structure workshops and houses with large displacements, caulking and sealing of wall expansion joints, containers, refrigerated trucks, etc.
Waterproof sealant uses:
1.The adhesive sealing surface should be dense, intense, dry, and clean without moisture, oil, dust, etc.
2.Cut the sharp mouth to meet the requirements, and use a quick tool to poke open the aluminum sealing film inside the glue outlet.
3.Load the glue gun and squeeze the glue into the place that needs to be sealed.
4.When it is necessary to smooth the surface, it should be smoothed with bamboo chips dipped in soapy water before the surface is dry
