Gelest® Primer A1 Adhesive/primer for low polarity resins PP1-SBPA1
Applications:
- optical-electronic interface device assembly and packaging
- thin film adhesive protective coatings
- primer on metals, glass and concrete for organic coatings
Description: Gelest® Primer A1 is a linear polymer containing reactive alkoxysilane, anhydride, and unsaturation functionality dissolved in toluene. It is suitable for nonpolar resins including silicones and polyolefins. The primer is normally applied to the inorganic substrate and after drying the polymer is applied. Provide thin adhesive films that act as primers for organic resins on metal and glass substrates. Sibrid® Primer A1 is a silane modified organic polymer with the ability to form thin films on siliceous and metal substrates and then crosslink with subsequently applied organic resins at room or moderately elevated temperatures.
Solution Properties:
- form: amber solution
- solids: 12-14%
- flashpoint: 5 °C
- specific gravity: 0.85
- viscosity: 2-5 cSt
Shelf life: 12 months when stored below 25 °C in sealed containers. Keep container sealed after dispensing product.
Cautions: Use in a well ventilated area. Flammable. Avoid contact with skin and eyes. Product is moisture sensitive. Containers should be tightly sealed.
Application Methods:
Gelest® Primer A1 is applied as a coating by spraying, dipping or brushing. The solvent is removed by evaporation in an exhausted area Simultaneous with evaporation, moisture induced cross-linking is initiated. After drying, maximum bond strength with the substrate is achieved by heating to 80 °C for 30 minutes, but normally this is not necessary.
Gelest offers pure silicone fluids (not blends) with a wide range of refractive indices. Listed below are fluids with refractive indices and viscosities. Detailed information including chemical structure, physical properties, electrical properties and chemical structure can be found in the Gelest product literature entitled Silicone Fluids: Stable, Inert Media. Fluids with the same product code prefix can be blended to exact refractive index requirements.
