Q1: What types of resin systems is Crosslinker 015 compatible with?
A: Crosslinker 015 is specifically formulated for use with hydroxyl-functional acrylics, polyesters, and certain alkyd resins. It demonstrates good reactivity under ambient or moderately elevated cure conditions and is not recommended for epoxy or amine-cured systems.
Q2: What is the typical dosage range for Crosslinker 015 in coating formulations?
A: Dosage depends on formulation requirements, target performance, and resin functionality, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to total resin solids.
Q3: Does Crosslinker 015 require a catalyst to achieve full cure?
A: While Crosslinker 015 can proceed without added catalysts under appropriate thermal conditions, the inclusion of a weak organic acid catalyst—such as p-toluenesulfonic acid—is often recommended to enhance crosslinking efficiency and reduce required cure temperature or time.
Q4: How should Crosslinker 015 be stored to maintain stability and shelf life?
A: Store in tightly sealed original containers in a cool, dry place away from direct sunlight and moisture. Under these conditions, unopened material typically maintains its reactivity and handling properties for up to 12 months from the date of manufacture.
