Polysulfide building sealant production indicators based on the standard is JC/T483-2006,** or Oman building sealant manufacturers small series for building caulking sealing waterproof two-component polysulfide sealant type difference. In order to facilitate everyone to better grasp the understanding of two component building polysulfide sealing paste.

Type: Polysulfide building sealant is divided into two categories according to fluidity: non-sagging type (N) and self-leveling type (L).

According to the amount of stretch film is divided into: high modulus (HM) and low modulus (LM) two sub-levels.

Polysulfide sealant building product labeling is in the following order: name, type, grade, sub-grade, standard number.

Example: Grade 25 low modulus non-sagging polysulfide building sealant is labeled: Polysulfide building Sealant N 25 LM JC/T483-2006.

Polysulfide building sealant product requirements from the product appearance and physical and mechanical properties of two aspects to identify:

The appearance of polysulfide building sealant should be uniform paste, no crust and lump, and the color between components should be significantly different. Polysulfide sealant color and supply parties agreed to compare, there should be no significant difference.
