Question 1

How does SAL-30 prevent fisheye defects compared to pure silicone additives?

Accepted Answer

SAL-30 uses a block copolymer architecture where the acrylate segments anchor the molecule into the coating matrix, preventing migration and silicone accumulation at the film surface. This eliminates the recoatability and fisheye problems common with PDMS-based leveling agents, while retaining the surface tension reduction of the silicone block.

Question 2

What is the recommended addition method for SAL-30 in waterborne formulations?

Accepted Answer

Add SAL-30 to the letdown stage under moderate agitation. For UV coatings, add directly to the oligomer blend before addition of photoinitiator. The butyl glycol carrier is compatible with most waterborne binders; no pre-dilution is required. Dosage of 0.2–0.3% typically delivers optimal flow and leveling without cratering.

Question 3

Is SAL-30 compatible with both anionic and non-ionic waterborne dispersions?

Accepted Answer

Yes. SAL-30 is non-ionic and compatible with anionic acrylic dispersions, polyurethane dispersions, and most non-ionic systems. Compatibility with cationic systems should be verified by jar testing. It is stable in pH ranges of 6–10, covering the majority of commercial waterborne binders.
