Jowat®409.59 Primer
■The viscosity is reached only after stirring.
■After stirring fluid, easy to process, dries fast.
■We recommend that all materials coming into contact with the glue are made of high-quality stainless steel (German standard V2A according to DIN EN 10027 – W-No. 1.4301 or better quality) or of inert plastics, e.g. Teflon, PP, polyamide. Avoid contact with other metals like zinc, brass, copper or aluminum. For more information, please contact the equipment manufacturer or our technical service.
■Apply with gravure or foam rubber roller, in a thin and even layer. Maximum application amount: approx. 10 g/m² (dry). After application, the primer has to be completely dry; any water remnants may cause flawed bonding. Before primer application, it is imperative that polypropylene (PP) surfaces undergo a new corona or flame treatment. In order to achieve good adhesion results, it is necessary to add 3 – 5 % of Jowat® Crosslinking Agent 195.00 or 195.70. The mix of primer/crosslinking agent has to be processed within the pot life duration. Preliminary testing has to be carried out in order to establish optimum drying conditions. Uneven or too thick application as well as the use of insufficiently stirred material (sedimentation) will lead to flawed bonding.
■Roll coated substrates only after complete drying.
■The processing temperature of the primer and of the materials to be coated should be between 15 and 25 °C.
■Pot life:
▲At 20 °C with e.g. 5 % Jowat®
▲Crosslinker 195.00 or 195.70 [h]: max. 4 (shorter at higher temperatures)
▲Appearance: white
