Other hazards which do not result in classification
This mixture contains no components considered to be persistent, bioaccumulative and toxic (PBT), very persistent and very bioaccumulative (vPvB) or identified as having endocrine disrupting properties at levels of 0.1% or higher. This product contains an inert coarse sand which is not hazardous to health or the environment. The sand does not contain any respirable crystalline silica which is hazardous to human health. Respirable crystalline silica (quartz) may be generated if the product is ground, abraded or otherwise processed. In its undiluted state (100%), dibenzoyl peroxide is classified as Organic Peroxides, Type B (may undergo a thermal explosion in packaging). The dibenzoyl peroxide concentration in the Wirelock Booster kit is 15 - 25%, thus the mixture is much more stable and downgraded to a Type G classification. This has been determined by our manufacturer experimentally, though no test data has been given. A polymerisation reaction occurs when the resin system (Part A) is combined with the catalyst / hardener (Part B) / Booster Kit which has the potential to generate significant heat. The product has a powerful bonding action on end use. Users should take appropriate precautions. Only use Wirelock Booster kits that match the size of the Wirelock kit being used. Always add the Booster kit to the Wirelock powder first and then add the resin. Risk of dust explosion.
