- Resin Use
ATTSHIELD 41 resin is designed for use with a methyl ethyl ketone peroxide (MEKPO) initiator system. It can also be used with benzoyl peroxide (BPO). CRV-9100M is extremely sensitive to the content of the RP-V promoter. If the gel time needs to be adjusted, then the dosage of RP-V promoter must be controlled to speed it up or slow it down. Maintenance of MEKPO catalyst level 0.8% -1.5%. During curing, CRV-9100M is also sensitive to temperature changes. For best results, the use of less than 0.7% MEKPO catalyst is not recommended. If a long gel time is required at high ambient temperature, then the RP-V level of the promoter should be maintained at 0.6-1.0%, and the MEKPO level should be maintained at 0.7%-1.2%. If a longer gel time is needed, it can be adjusted using a 10% solution of tert-butyl catechin. At an ambient temperature below 15℃, may need to add additional dimethylaniline.

Safety & Health
- Safety
- Store below 25 ℃ in order to maintain optimum resin properties, and avoid exposure
Heat sources such as direct sunlight, steam or flames.
- Keep containers sealed to prevent moisture absorption or monomer loss.
- Do not add metal salts (promoters) or promoted resins to the peroxide.
- Do not add organic peroxides to hot diluent
