Jowacoll 102.49

For processing with Jowat® crosslinking agent 195.60 or with Jowat® crosslinking agent 195.62

Application:	Glue for bonding hard wood species (oak, beech), species with high resin content: (pine), tropical wood species (teak, meranti), and wood with moisture content up to 15 %. For assemblies exposed to direct weathering, with adequate surface protection, e.g. for window frames or formwork panels

Basis:	Copolymer dispersion

Characteristics / Directions for Use:	Jowacoll® 102.49 has to be processed with Jowat® crosslinking agent 195.60 or 195.62. Very high water-resistance, temperature resistance, mechanical strength, very good joint-filling properties, relatively resistant to solvents, excellent long-term heat resistance. When used correctly, Jowacoll® 102.49 will meet the requirements according to D4 under EN 204/205, and the watt ’91 > 7.0 N/mm² (tested by the ift Rosenheim). Without hardener, the durability class D2 according to the EN 204/205 will be reached We recommend that all materials coming into contact with the glue are made of high-quality stainless steel (German standard V2A or better) or of inert plastics, e.g. Teflon, PP, polyamide. Avoid contact with other metals like zinc, brass, copper or aluminum. For more information, contact the equipment manufacturer or our technical service. Mixing ratio: Jowacoll® 102.49 with Jowat® Crosslinking agent 195.60 = 100 : 7 - 15 ppw Jowat® Crosslinking agent 195.62 = 100 : 7 - 15 ppw The mixing has to be carried out very thoroughly; if the quantities are high, use of a feeding-mixing unit is recommended. Suitable for all standard applicator systems, like brush, spatula or roller. Avoid contact with iron, tanniferous wood may discolour. After mixing with the Jowat® crosslinking agent 195.60/195.62, do not close the containers tightly, since they may burst due to formation of CO2.

Longer pressing times will result in higher strength, according to all test
methods.Tested at 8 - 10 % wood moisture, 20 °C, following EN 205
(application amount > 150 g/m², one-sided). The hardener may not come into
contact with water or moisture, otherwise it will cure prematurely.

Cleaning:	Machines and equipment may be cleaned after use of the mixed components with warm or cold water, using Jowat® Cleaner Concentrate 192.40. Parts soiled with crosslinking agent are to be cleaned with Jowat® Thinner 401.40/402.30.

Storage:	May be stored in properly closed original containers, cool and dry 15 - 25 °C) For expiry date, please refer to label. Protect against frost!
