序号 Km-922
产品名称 硅烷改性树脂(MS树脂)KM-STP380
CAS号 216597-12-5
详细介绍

English name: Silane Terminated Polyether Polymer / Silane Modified Polymer (MS Polymer)-KM-STP380;

Synonyms: Silane terminated polyether polymer (STP Polymer); polyether-based silaneterminated polymer;  Silane terminated polyether; Silane-modified polymers; Silyl-TerminatedPolyether

CAS No. 216597-12-5

MF: (C3H6O)nC14H32N2O9Si2

Description:

 

KM-STP380 is equivalent to Wacker GENIOSIL® STP-E35. It is alkoxy silane terminated polyether polymer. It could be applied in moisture curing elastic sealant, elastic structure sealant and sealing coatings. Sealants based on KM-STP380 not only have excellent adhesion properties, but  also have adhesion to broad range of substrates. Different from polyurethane and silicone system, this formulation has   no solvent and isocyanate, as well as no bubbles and odour generated from curing. It is especially suitable for construction industry,   transportation   industry  and  general   industry application.

Properties and Features:

  • High Activity , Low – medium Modulus
  • High transparence
  • Good adhesion strength and tensile elasticity
  • Fast curing , non-tin catalysts used if needed, more eco-friendly
  • Excellent aging and yellowing resistance
  • Excellent water resistance and solvent resistance
  • Excellent elastic recovery rate
  • Excellent storage stability
  • Solvent free , odourless , eco-friendly
  • Could be blended with other Kemiworks polymers

Storage:

Because this product is moisture sensitive, If unopened and stored  at  4 ℃ -30℃   dry  environment,  the  shelf  life  is  12  months. Use it as soon as possible if opened, the remain products should  be  resealed  and  stored at 4 ℃-30℃  dry environment. But if shelf life expired, you can still use it only after your positive confirmation of production performance.

Package:

50kg plastic drum , 200kg/Iron drum or  1000kg/IBC drum
