ATTSHIELD 47 resin is designed for use with methyl ethyl ketone peroxide (MEKP) as a catalyst (Butanox M-60, Promox P200 TX). It can also be used with benzoyl peroxide (BPO). ATTSHIELD 47 is an unaccelerated resin and requires a 6% cobalt octoate solution as an accelerator. ATTSHIELD 47 is extremely sensitive to the content of the accelerator. It is necessary to control the dosage of the accelerator in order to increase or decrease the gel time. During the curing process, ATTSHIELD 47 is sensitive to changes in ambient temperature. For best results, the use of less than 0.7% PMEK catalyst is not recommended. For good resin curing under normal environmental conditions, the accelerator level should be maintained at 0.5-1.0%, and the PMEK level at 0.7% - 1.2%. If a longer gel time is needed, it can be adjusted using a 10% solution of tert-butyl catechin (inhibitor). At an ambient temperature below 15℃, it is necessary, add additional dimethylaniline (may cause yellowing of the laminate).

Safety & Health
- Safety
- Store below 25°C in order to maintain optimum resin properties, and avoid exposure to direct sunlight.
- Keep containers sealed to prevent moisture absorption or loss of monomer.
- Do not add an accelerator (accelerator) to the catalyst (PMEK).
- Do not add organic peroxides to hot diluent
Storage & Handling
