Silane Modified Polyether Sealant


SMP581 Polyether Sealant


Polyether Sealant 590ml

Product Description

SMP581 silane modified polyether sealant a one-component neutral-curing low-modulus sealant product with a joint movement capacity of class 20. The product has good bonding ability to most building materials and plastics such as concrete, stone, glass, aluminum, wood, polycarbonate (PC), etc. It can be widely used in prefabricated buildings, urban integrated pipe corridors, balconies and indoor and other fields of caulking and sealing of joints of internal and external walls of various buildings.
Product Features

  • Environmental product: ultra-low VOC, non-toxic and tasteless, no pollution and no corrosion to the substrate;
  • Good flexibility: low modulus, which can reduce the impact of internal stress caused by seam displacement changes on the durability of the sealant and reduce the risk of debonding and cracking. It has good flexibility and can maintain good bonding and sealing performance under the change of displacement of building joints.
  • Excellent adhesion: excellent adhesion to most building materials and plastics such as concrete, stone, glass, aluminum, wood, polycarbonate (PC);
  • The joint movement capacity is ±20%. For the normal expansion and shear deformation of building joints, this product can maintain the same performance and play an effective sealing and bonding effect;
  • Excellent elasticity, weather resistance and fatigue resistance.
  • Good paintability: the surface is paintable, and with Baiyun adhesion promoter, it can better solve the problem of decorative mortar, real stone paint and other finishing treatment on the glue surface.
  • Good operability: One-component, easy to operate, has good extrudability in the range of 4℃~40℃, and can be applied by extruding with a sealant gun.

Main applications

  • Caulking and sealing of internal and external walls of assembled buildings, urban integrated pipeline corridors and home interiors.
  • Bonding of various building materials, such as concrete, stone, glass, aluminium, wood, etc.
  • Other bonding and sealing applications in the construction field where this product is suitable.

Usage restrictions

  • Not suitable for use in locations where the operating temperature is permanently above 80°C.
  • Not suitable for use in glass mounting applications.
  • Not suitable for use in densely ventilated areas where the sealant needs to absorb moisture from the air to cure.
  • Not suitable for use in areas subject to continuous water immersion or year-round humidity
  • Not suitable for use on materials that will leach grease, plasticisers or solvents, such as surfaces of oil-impregnated wood.
  • Not suitable for bonding polypropylene (PP), polyethylene (PE), polytetrafluoroethylene (PTFE).
  • Not suitable for work when the surface temperature of the material is below 4°C or above 40°C.
  • When bonding cement and concrete substrates, the substrate must be completely dry and maintained for 7 days before construction, otherwise the bonding performance will be affected.

Steps in use

Before using this product, the operator must read the product safety information carefully.

  • The work surface must be clean, dry and free from dirt.
  • Apply protective tape to both sides of the work surface and use a suitable lining material in the caulking.
  • Cut the spikes to the required size and apply the amount of sealant to provide adequate contact with the sealant sealing surface.
  • Trim and remove the protective tape within 10 minutes of application.
  • Good ventilation should be maintained during the application and curing process.
  • To ensure optimum bonding results, a bonding test should be carried out before the work starts and must be used in conjunction with a primer if necessary. Periodic peel and stick tests should be carried out during the construction process to ensure quality.

Safety instructions
This product is not toxic when fully cured, but contact with eyes should be avoided until cured, if contact is made, flush with plenty of water and seek medical attention; uncured product should be kept away from children.
