Weicon Activator For RK-1300 and RK-1500, 10562100, 100ML

Activator for processing RK cartridges or large containers. Surface pre-treatment: To ensure perfect bonding, the surfaces to be joined must be clean and dry (to clean and degrease use Weicon Surface Cleaner). The highest strength values can be achieved through additional pre-treatment of the surfaces, such as roughening using blasting or abrasive agents. Several plastics, in particular polyamide,PTFE, polyolefin etc. are only to be bonded after special surface treatment, for example using fluoridation, low-pressure plasma, corona, flame impingement etc.
Processing:

Processing of the RK Activator The RK Activator is applied, depending on the size of the bonding gap, on either one side or both sides of the surfaces to be bonded (brush, spray, dip). In case of bond lines with a max. of 0.4 mm in width, the Activator only needs to be applied on one side, for bond lines of up to a max. of 0.8 mm in width and/or rough, porous or passive surfaces (chrome, nickel etc) the Activator must be applied on both sides. For smooth plastic and metal surfaces, approx. 30 g/sq.m is necessary, for rough and porous surfaces up to 150 g/sq.m of Activator may be necessary. The evaporation time at room temperature (+20 Deg.C) is at least 5 minutes. A significant advantage to other adhesive systems is that the coated components can be stored up to 30 days at room temperature (+20 Deg.C) without loosing effectiveness.

Processing of the RK Adhesive

The Adhesive is applied only on one side and normally on the surface which is not coated with Activator. The width of the bond line can be up to 0.80 mm (only if the Activator is applied on both sides). Bond lines of 0.15 mm to 0.25 mm in width always have the highest tensile shear strength.

Processing Temperature

The processing should take place at room temperature (approx. +20 Deg.C). Higher temperatures, e.g. +40 Deg.C shorten the positioning and curing times by approx. 30%, lower temperatures of approx. +10 Deg.C increase the respective times by approx. 50% and up to +5 Deg.C almost no reaction occurs anymore.

Safety and Health:

When using Weicon products, the physical, safety technical, toxicological and ecological data and regulations in our EC safety data sheets (www.Weicon.com) must be observed.
