Product Description

Product Description

SV-998 It is a kind of two-part room temperature vulcanized polysulphide sealant with high performance especially formulated for insulating glass. This sealant has excellent elasticity, heat gas penetration and adherent stability to various glasses.

  Features

* Structural performance

* Cures to form a durable, long-lasting, high-modulus, flexible, weather tight bond

* Excellent UV and weathering resistance

* Excellent unprimed adhesion to glass and metal substrates, such as galvanized steel and aluminum

* Superior long-term durability

* Consistently nonslump, permitting automated glazing 12 month shelf life from date of manufacture Noncorrosive byproducts Low

* shrinkage (< 5 percent)

* Unmatched service temperature range

Application

 

1.Two parts of SIWAY S-998 packaged respectively of composition A(basic gel) and a composition B(curing agent), are mixed together according to the ratio of A:B=10:1 before application. The curing rate may be modulated by changing the weight ratio of composition A to composition B over the range of 12:1 to 8:1 according to different environment conditions

2. The mixture of sealant can be classified into two methods one by hand-made and the other by special extrusion machine. It is noticed that SIWAY SV-998 sealant should be scratched and mixed by the spatula along the same direction repeatedly to prevent gas bubble trapped in sealant in the method of hand-made.The homogeneity of mixture can be measured bybutterfly-type method as listed in the following figure: Good Mixture Bad Mixture

3. The surfaces of insulating glasses must be dry and clean.

4.SIWAY SV-998 should fill the joints completely which need to be caulked during the course of making insulating glass.

5.Gun mouth should be assured to move along the same direction at uniform velocity to make the ioints full of sealant and prevent

the gas bubble production due to moving too fast or back and forth in the method of using special extrusion machine.

6. The sealant overflowing the joints should be pressed back at once by spatula to make the sealant contacting with the sides of the joints completely and smooth the surface of the joints along the same direction.
