BYK® -2616

BYK®-2616 by BYK is a low-emission additive for the removal of moisture in PVC plastisols and to accelerate ambient curing acrylate systems. It can remove large quantities of moisture in a very short time from the system to be processed. It contains wetting and dispersing carrier media. A special processing technology is used to activate and stabilize the inorganic moisture absorber, calcium oxide. It prevents blistering when coating glass or synthetic non-woven materials with PVC plastisols for flooring and roofing felt. Also, prevents surface defects such as bubbles and cratering when processing PVC pastes using casting and rotational molding processes. It absorbs moisture that enters into the system through fillers and pigments. It enables the uncomplicated processing of damp regenerated plastics that have been stored for long periods. The recommended level for PVC plastisols is 0.75-2.5% additive (as supplied) based on the total formulation, depending on the moisture content of the system. BYK®-2616 is used as an accelerator in acrylate systems which are cured using TBPM (tert-butyl monoperoxymaleate). It offers stable particle size distribution, no sedimentation, no CO₂ uptake and simple dosage of the liquid additive. The recommended level for ambient curing resin systems is 1-2% additive (as supplied) based on the liquid resin (syrup). It is in line with EU Directive 2011/65/EC (RoHS 2), EU Directive 2002/96/EC (WEEE), EU Directive 94/62/EC (Packaging Waste) and CONEG Toxics in Packaging. It complies with REACH Regulation (EC) No 1907/2006. The shelf life of this product is 60 months.
