Main uses of RTV SILICONE SEALANT (ACID) in production
The polymer backbone of RTV SILICONE SEALANT (ACID) is mainly composed of silicon-oxygen-silicon bonds, and other organic sealants whose polymer backbone is mainly composed of carbon-carbon bonds (such as polyurethane sealants, acrylic sealants, Compared with polysulfide sealant, etc.), the remarkable feature is excellent high and low temperature resistance and weather resistance.
Generally, organic sealants will age quickly at 100°C and cannot be used normally, while RTV SILICONE SEALANT (ACID) still maintains good elasticity and strength at 150°C and can be used for a long time. At -20℃~-30℃, the general organic sealant will become brittle and lose its elasticity, while the embrittlement temperature of general RTV SILICONE SEALANT (ACID) is -60℃~-70℃, and it can still be used at a low temperature of -50℃ Retains good elasticity and strength without becoming brittle, hardening or cracking. When exposed to ultraviolet rays, ozone and wind and rain for a long time, the general organic sealant will deteriorate quickly, while the service life of RTV SILICONE SEALANT (ACID) can reach several decades.
In the construction industry, RTV SILICONE SEALANT (ACID) must be resistant to high temperature (80°C), low temperature (-30°C), aging resistance (ultraviolet rays in sunlight), and water resistance. The tungsten putty first used in construction will fail in sealing within 2 years; later, neoprene sealant will only have a service life of 3-5 years; and then the acrylic sealant that will appear later, with good quality, can last for 10 years. The above service life, but the performance is not high, can not be used on the building curtain wall. Until the emergence of reaction-curable polysulfide, polyurethane, and silicone sealants, there will be sealants with superior comprehensive performance and good durability that can meet building requirements to a certain extent. RTV SILICONE SEALANT (ACID) has a market share of more than 80% in the construction industry sealant. This is because silicone sealants have almost all the advantages of sealants required for construction, and are inexpensive. High quality RTV SILICONE SEALANT (ACID) has a service life of more than 50 years.
MODIFIED ACRYLIC AB ADHESIVE (BOXES) uses methyl methacrylate as the main raw material, with tougheners, reinforcing agents, stabilizers, initiators, polymerization inhibitors, etc., two components synthesized through advanced technology (A, B) Reactive structural adhesive.
