Creative Materials 128-19

Chemical Family: Epoxy & Epoxy Derivatives

128-19 is a screen-printable, B-stageable, one-part epoxy adhesive, suitable for application by screen-printing and syringe dispensing. 128-19 is designed to exhibit minimal flow during bonding. This product provides bonds of dissimilar materials and has has excellent adhesion to copper, aluminum and ceramic and a variety of other substrates. Additional applications include, but are not limited to, assembling electronic components. This system features excellent thermal stability and flexibility in the B-Staged form. 128-19 is an electrically insulating version of 125-22.\nFeatures

Technology: Ready-to-Use Products
Procedure: Apply adhesive to substrate or release liner. Next apply heat to advance the curing to the non-tacky stage when cooled to room temperature. A temperature of 100°C to 120°C for 5 to 15 minutes is required, B-Stage time is mass related. Increased B-Stage time helps reduce flow during bonding but might slightly reduce the bond strength. Too much B-Staging will cause the adhesive to have low bond strength. User is encouraged to experiment for optimum drying time at a given temperature.
Bonding Procedure: To use, apply b-staged adhesive to one part, carefully align parts to be bonded, apply uniform pressure to maintain location. Cure for 15 minutes at 200°C, or 30 minutes at 175°C, or 1 hour at 150°C. For better adhesion of the bstaged film to the first part, it is suggested to warm the part to 40°C. Cure times given are mass related, timing should start after adhesive and substrates reach curing temperature. Other cure time and temperatures can be used.
Curing Guidelines: These temperatures and times are presented as a guide only. The end-user is encouraged to experiment to determine optimum curing schedule.
Safety and Handling: Use with adequate ventilation.; Keep away from sparks and open flames.; Avoid prolonged contact with skin and breathing of vapors.; Wash with soap and water to remove from skin.
Application Methods: Injection
Screen Coating
Handling: Material is ready to use as received. Store frozen to maintain consistent flow properties. Allow material to warm up to room temperature before opening container. It is important to re-suspend any settled filler before using. Be careful not entrap air while mixing. 128-19 can be thinned with small amounts of CMI 113-12 (fast drying), or 102- 03 (slow drying) thinners.
