Product description:
TEROSON MS 9399 is a highly viscous, sag-resistant, two-component adhesive based on silane-modified polymers, which cures independently of the atmospheric moisture to an elastic product . It is free from solvents, iscoyanates and silicones. TEROSON MS9399 has good UV and weathering resistance and can be employed for bondings in indoor and outdoor uses.

Steps to achieve the best adhesive results:
Pre-Treatment
The adhesion surfaces must be clean, dry, oil and grease free. Depending on the surface it may be necessary to roughen the surface by mechanical means or to use a primer/adhesion promoter to provide best adhesion. For plastics surfaces we recommend the use of Teroson SB 450. When manufacturing plastics, external release agents are often used; these agents must be absolutely removed prior to starting bonding or sealing. Due to the different compositions of paints, especially powder paints and the large number of different substrates, application trials before use are necessary. When bonding and sealing PMMA, e.g. Plexiglas®, and polycarbonate, e.g. Makrolon or Lexan, under tension, stress corrosion cracking may occur. Application trials before use arenecessary. There is no adhesion to polyethylene, polypropylene and PTFE. Substrates not mentioned above should be subject to trials.

Application
TEROSON MS 9399 is contained in a 2 x 200 ml cartridge set (components A and B) which also contains a static mixer. To openthe cartridges, the metal cap must be removed and the green plug pulled out. Now, the static mixer is screwed onto it. The cartridge setis then placed into the suitable compressed-air pistol. When the pistol handle is actuated, the material is pressed through the static mixer, whereby the two components are automatically mixed. The first 10 ml of the adhesive pass should be rejected, owing to the fact they may not have been mixed correctly. If the application of adhesive is interrupted for more than 5 minutes at 23° C, the static mixer should be replaced. Otherwise, the increase in viscosity could cause the static mixer to burst. At higher processing temperatures interruption times will decrease. TEROSON MS 9399 is applied directly to the substrate. For the processing equipment that we recommend, the processing pressure should not exceed 5 bars. The parts which are to be bonded must be joined within the specified processing time. Surplus material is to be removed immediately after application. Other packagings are available on request.

Cleaning
For cleaning application equipment contaminated with uncured TEROSON MS 9399 we recommend the use of Cleaner+Diluent Teroson A, D or FL.
