Reduced preparation time with void-free A/B injection cartridges; pre-measured for easy mixing
Primer-free application on a wide variety of materials
Fast 4-hour cure time, with full adhesion within 24 hours at room temperature
Secure bonding to a wide range of surfaces in ambient conditions reducing fixture requirements and eliminating special curing conditions
Reliable, temperature-resistant performance; capable of withstanding operating temperatures from -65˚F to 500˚F (-54˚C to 260˚C)
Outstanding performance in deep-section applications with large-area bonding capability
Thermosil 3005 is an environmentally friendly, fast curing silicone elastomer formulated to provide rapid, same-day curing and a secure bond without releasing hazardous by-products.
Thermosil 3005 is available in injection cartridges, compatible with popular pneumatic and mechanical dispensing guns.
Applications & Uses
- Applications
- Important Application Information
Applying the Product: Thermosil 3005 bonds to a wide range of clean materials without the need for a primer. Clean and prepare surfaces with a solvent wash, degreaser, or abrasion.
Application Note: Specific surface preparation may be required for optimal bonding performance on some plastics or composite materials. Please contact FMi Chemical if you have questions about a particular application of this product.
Curing and Bonding: Thermosil 3005 cures in 4 hours and exhibits full adhesion within 24 hours at 75˚F (24˚C). Accelerated curing can be achieved with the application of heat.
Curing Inhibition: Thermosil 3005 is a dual-cure addition reaction silicone rubber. Avoid contact with common silicone inhibitors or poisons such as amines, sulfur, organometallic compounds, or tin-catalyzed rubbers.
Tooling: Thermosil 3005 can be tooled with acetone, methyl ethyl ketone (MEK), or isopropyl alcohol (IPA).
- Mixing Thermosil 3005 A/B Injection Cartridges
FMi Chemical recommends the use of automated (Semkit® type) mixing equipment for Thermosil 3005 A/B injection cartridges. Thread the Part B dasher rod into the top of the Part A cartridge. If applicable, use a ramrod to inject Part B into the middle of Part A. Install the joined cartridge and dasher rod unit into the mixer and adjust the mixer's settings for the correct cartridge size. For 2.5 oz cartridges, mix the material for 70 strokes, or 2½ minutes, at 100 rpm. When mixing is complete, unthread the dasher rod and install the cartridge in a pneumatic or mechanical dispensing gun. For information about mixing varying cartridge sizes, automated mixing procedures, and alternative mixing methods, please contact FMi Chemical.
