CYMEL® XW 3106

CYMEL® XW 3106 Resin can be formulated with good catalyzed coating stability with the addition of a primary alcohol, such as ethanol or n-butanol, at loadings of 10-20% on total resin solids.

CYMEL® XW 3106 Resin requires the addition of a sulfonic acid catalyst, such as CYCAT® 4040 catalyst or CYCAT® 600 catalyst, at levels of 2.0-4.0% on total resin solids, in order to obtain effective cure for both ambient and heat-cured applications. The acidity of other formulation components may contribute to the reaction and should be evaluated in combination with the catalyst.

CYMEL® XW 3106 Resin is a very effective crosslinker for acrylic, polyester, and alkyd polymers containing primary hydroxyl functionality. The coatings demonstrate very good flow, gloss, early film hardness, early print resistance, and chemical resistance. Polyols with high T_g (>40°C) should be avoided as these may limit the network development with this crosslinker.

• CYMEL® XW 3106 Resin has a shelf life of 1800 days from the date of manufacture when stored at temperatures below 32°C. Although low temperatures are not detrimental to stability, the viscosity of the product will increase, possibly making the resin difficult to pump or pour.
• CYMEL® XW 3106 Resin viscosity can be returned to normal by gentle rewarming; However, care should be taken to avoid excessive localized heating, which can result in an irreversible increase in viscosity.
