Customized WATERPROOF JOINTING SEALANT products is a sealant made of liquid polysulfide rubber as the main material, together with tackifier, accelerator, reinforcing agent, etc. This kind of sealant has excellent resistance to fuel oil, hydraulic oil, water and various chemical properties, as well as heat resistance and aging resistance. According to the composition, it can be divided into two-component (or three component) and single component types. The process of premixing grinding filling is adopted. Customized WATERPROOF JOINTING SEALANT products is suitable for long-term water immersion building joint sealing, and has good bonding performance with the concrete, such as: underground waterproof joint, aircraft runway, water and sewage storage, sewage pool, underground works, and large water conservancy projects all use waterproof joint sealant, which has high elongation rubber shape high elastomer with aging resistance, durability, air tightness, and waterproof bonding properties. As the functional data of building curtain wall, MS SEALANT FOR CONSTRUCTION has the functions of building sealing, waterproof, sound insulation, energy conservation, corrosion prevention, pollution prevention, fire prevention, decoration, structural elastic connection, structural safety and durability.

The functional requirements of customized WATERPROOF JOINTING SEALANT products mainly depend on environmental factors, such as UV radiation aging in sunlight, oxidation of oxygen and ozone, aging of water and steam, influence of environmental temperature change, wind load, effect of shear force, load of circulating machinery (tightening/stretching), harmful pollution (such as acid rain, salt spray, etc.), and influence of microorganisms and macroorganisms. After the Structural adhesive is determined and the characteristics of sealant products are understood, the sealing of customized WATERPROOF JOINTING SEALANT products depends on the strict and correct construction procedures of sealant. The construction requires not only correct and skilled operation skills, but also conscientiousness, responsibility and patience, and then avoid the occurrence of shortcomings. Many facts indicate that the shortcomings of joint construction and careless sealing construction are the important reasons for the formation of penetration. Moreover, it is very difficult to find the leakage source and seal, which is time-consuming, laborious and adds unnecessary costs.

Inadvertent construction of waterproof joint sealant will also cause potential safety hazards. Before construction, all important data of node planning, dimensions of waterproof joint sealant, drainage treatment, compatibility and cohesiveness of customized WATERPROOF JOINTING SEALANT products with auxiliary data and bonded substrate shall be approved through collegial approval. The preparation of skills before construction shall be based on the requirements of the general construction progress plan, the construction period of the rules and the harmonious cooperation between other processes, determine the construction method of this process and the number of construction personnel required, and prepare the construction progress plan of this process. Check whether the appearance, dryness and joint dimensions of the bonding substrate conform to the drawings and construction requirements. The bottom layer that does not meet the requirements shall be handled. In addition to preparing the sealing materials according to the planning requirements, the materials shall be prepared according to the primer provided by customized WATERPROOF JOINTING SEALANT factory.

Before the construction of the primer, the bonding test can be carried out in the following simple way: take the practical bonding primer as the bonding body → stick the cellophane tape at one third of the longitudinal part of the surface of the sealant to be bonded → apply the primer at the remaining two-thirds of the longitudinal part → stick the adhesive strip sealant on the cellophane tape and primer → place it on the site until it is cured, and check the bonding. Before the construction of two-component polysulfide sealant, check the construction conditions, joint size, whether there are defects, etc. Cleaning of the bonded substrate: whether the surface of the bonded substrate is dull. To avoid failure in bonding, clean the oil stains, dirt, etc. on the surface with solvent by wiping with two cloths. The component ratio of customized WATERPROOF JOINTING SEALANT products shall be tested. The specific method can be determined by comparing the curing time with the data provided by our WATERPROOF JOINTING SEALANT manufacturer. The filled joint shall be filled with customized WATERPROOF JOINTING SEALANT products. Before trimming the joint, the sealant shall be compacted into the joint with external force, and the sealant shall fully touch the bonded surface. During the construction of Structural adhesive, the same batch of bonded materials can be bonded at the same time to prepare samples for bonding inspection. Touch up: After the sealant is applied, the joint shall be trimmed immediately, and the trimming pressure shall be uniform in one direction, and then the dirt strip shall be removed quickly to prevent the dirt strip from being stuck to customized WATERPROOF JOINTING SEALANT products or base material.
