OM905 two component polysulfide sealant
Product description:
OM905 two-component polysulfide insulating glass special sealant (OM905 for short) is a two-component, solvent-free, room temperature curing sealant. OM905 has high strength and high elasticity; It has good adhesion to glass, aluminum and other clean surfaces. OM905 Low viscosity, convenient construction, suitable for hollow glass automatic production line (mechanical construction) and manual production line (manual construction).
Product use:
0M905 is used for the second edge seal of insulating glass, widely used in construction, transportation, refrigeration and other industries of insulating glass seal. 0M905 has good bonding with glass, and has good bonding with most insulating glass spacer materials. Including aluminum, aluminum, stainless steel
Etc. OM905 has excellent oil resistance, solubility resistance and wide chemical properties, can avoid the failure of insulating glass caused by the incompatibility of sealant and glass material, so as to provide excellent protection for insulating glass. Because of its low permeability to most solvents, oils and plasticizers, OM905 is suitable for non-rigid warm edge spacing systems such as TPS. 0M905 has good compatibility with polyisobutene sealant. For aerated insulating glass, sealant. The small thickness is 5.0mm. (In practical application, appropriate thickness should be determined according to the size of insulating glass unit, weight, size of spacer frame and design of glass system.)
Limitations:
Insulating glass prepared with OM905 or any sealant containing polysulfide protogel shall not be used for frameless mounting applications (curtain walls), nor shall it be used in
The sealant is applied under conditions of direct exposure to UV light. OM905 is designed for framing insulating glass.
Product features:

Security:
For health and safety reasons, check the product label and Material Safety Data Sheet (MSDS) before using this or any product.
Storage and shelf life:
This product should be stored in a cool, dry and ventilated place for 12 months.
Instructions for use:
Surface cleaning: The surface of the adhesive material must be clean, dry, dust and grease free, with perfect bonding performance, glass surface with manual or mechanical thoroughly clean, no film, low residue.
Mixing process: A, B two component ratio range is the mass ratio of A:B=100: (6-12), in this ratio range, can be adjusted by adjusting the proportion of A, B two components to adjust the curing speed of sealant (B component the greater the amount, the faster the curing speed; The smaller the amount of component B, the slower the curing speed); Mixing should be uniform, no color difference. Recommended. The optimal mixture mass ratio is 100:10. The optimal mixture should be constructed in approximately 20 minutes (23°C application period). With the increase of temperature, the applicable period is shortened.
Important: Mechanical degradation may occur if the mix mass ratio is less than 100:6. If the mixed mass ratio is greater than 100:12●, the final product performance will be slightly affected, but the current performance will be significantly changed.
Coating process: It should be coated along the same direction to prevent bubbles from being wrapped into the glue and reduce the sealing performance of the insulating glass.
Curing: It is required to work in an environment higher than 10°C and not lower than 5°C. The curing speed of OM905 depends on ambient temperature and humidity. The newly made insulating glass can not be cured in low temperature or soaked by rain. Try to make the desiccant can completely dry the air chamber, which can effectively avoid condensation on the glass plate; Initial curing for 5h can reduce the risk. Small. The curing time of the newly made insulating glass has not reached 24h, and it can not be exposed to the sun.
Cleaning: Immediately after completion of construction, remove uncured materials from tools and equipment with solvents. Compatibility of glass assembly: Compatibility testing of glass materials is recommended. Glass materials should avoid contact with any solvents, oils and materials containing plasticizers.
Transport: This product is non-hazardous and can be transported by train, car, ship and air.
