Application Information

Characteristics and Advantages

? For unsaturated polyester resins, gel coats, and casting systems, as well as for epoxy floor and polyurethane systems;

? Good performance in various adhesive application fields;

? Excellent defoaming properties in PU coatings.

? Due to good compatibility, this defoamer is especially recommended for transparent systems.

? PVC systems

When used with wetting and dispersing agents such as YINK-110 in pigmented systems, it can provide lower viscosity to the system, facilitating faster defoaming.

Recommended Applications

All unsaturated polyester resin systems, vinyl resins, transparent systems, acrylic resins, adhesives, PVC, epoxy systems, PU systems.

Recommended Dosage

0.1-0.8% based on the total formulation.

The above data are empirical dosages; the optimal dosage should be determined through a series of tests.

Packaging and Storage
