Recommended Applications

PERGASLOW BK-100 is used at ambient temperatures for lengthening: 1) the gel time of a mixture of UP resin / peroxide / accelerator. 2) the pot life of a mixture of UP resin / peroxide. 3) the pot life of a mixture of UP resin / amine accelerator. The inhibitor should be added to the resin first to create a maximum effect. After proper mixing, the peroxide and the accelerator can be added. Depending on application area and working conditions, the following inhibitor dosage levels are recommended: PERGASLOW BK-100: up to 0,05 phr
