The performance and life of 995 neutral silicone adhesive is a topic of long-term concern in the industry, manufacturers, construction units, direct users and designers are very concerned. The tiny strips are like sewing threads, elastic to the parts of the building and subject to corresponding forces. Like sewing thread, the amount and cost of this material is not large, but it plays a crucial role. Since most of the main materials of the building are inorganic, the durability of these main materials is generally guaranteed. However, the durability of silicone sealant in organic materials is not as good as inorganic materials, so 995 neutral silicone adhesive should be a controlling and restrictive material that affects the service life and structural safety of curtain wall buildings.

995 neutral silicone adhesive actual use of bonding properties how to deal with?

       This involves two very important indicators - adhesion failure area and adhesion strength, there is no doubt that we must ensure that the structural adhesive sufficient adhesion and adhesion durability. Non-adhesive bonding has some typical performance: some adhesive strips we pull off with not too much force, and the stripping surface is very smooth, there is not much residual rubber block, more is the strength of the pull is enough, but the adhesive damage area will exceed the standard. How to solve these bonding problems? Does not exist.. The current status of the industry should be such that standard materials, such as glass, can be perfectly adhered to very good, standard anodized aluminum profile, bonding also has excellent, but for a variety of new surface treatment of materials, bonding speed and effect may be poor. So now the common way is to hit some targeted base coating in adhesion, and the advantage of base coating is to improve the bonding condition on the interface, to avoid blindly adding too much unstable substance in the whole colloid, affecting the long-term use of silicone structural adhesive. Base coating is a solution that has been proven to be useful for a long time, and we hope that the industry will come to a consensus and not bother. At the same time, the selection of new materials should take into account the appearance and safety, and the construction unit should fully understand and cooperate.

       What are the advantages and disadvantages of neutral silicone adhesive as a building material?

       Silicone adhesive contains both organic groups and inorganic Si -- O structure, this structure makes it both inorganic and organic material performance, especially in the performance of excellent UV resistance, heat resistance and aging resistance, so it is the building curtain wall has experienced the test of time. The material has been used for more than 40 years abroad and 30 years in our country.

       However, silicone rubber also has disadvantages, it is not as good as C - C polymer compounds in acid and alkali resistance, hydrolysis resistance and chemical inertness. Therefore, under the action of acid and base, metal catalysts and other substances, and water vapor (especially the water vapor transmittance of this product is very high), silicone structural sealant may have chemical reactions to produce aging and performance decline.

       What is the aging performance of 995 neutral silicone glue?

       There is a key word here called chemical aging, physical aging is one aspect, chemical aging is a more core thing. Aging performance is mainly adhesion and tensile strength, elongation at break, elastic recovery rate and other properties are significantly worse, serious colloidal will become very hard, lose elasticity. Aging also has early and long-term performance. In the early aging degradation process of polymer, the core crosslinking point is degraded first, so that the crosslinking density and strength of the glue are decreased, but the basic polymer chain is still in, so although its elongation increases, the rebound rate decreases, and aging has begun. But if the depth of aging, polymer has been slowly decomposed, or even volatilized, leaving more filler, so the elasticity is very poor, will powder, hardening. So the tracking and inspecting of existing curtain wall has put on agenda of the industry in our country.
