Product Description

Wetting and dispersing additive for amine-accelerated UP, EP and, PUR systems and adhesives to reduce the viscosity in mineral-filled systems. It is embedded into the polymer matrix due to its OH functionality. Extends the gelling time with cobalt accelerators in UP resins.

Application

1)Thermosets

Special Features and Benefits:

BYK-W 969 is a monofunctional, deflocculating wetting and dispersing additive for mineral-filled, amine-preaccelerated polyester putty compounds as well as epoxy, acrylic, and polyurethane resins. It improves the wetting and dispersing speed of fillers during dispersion and reduces viscosity to enable an increased filler content to be achieved. The higher filler content improves sandability in applied and cured polyester putty compounds. The additive leads to a considerably increase in gelling time in cobaltaccelerated unsaturated polyester resins. It is suitable for all filled PUR systems. Due to its OH functionality, BYK-W 969 is incorporated in the polymer matrix and is therefore suitable for PUR systems in which fogging and emissions are critical (e.g., automotive applications).

2)Adhesives & Sealants

Special Features and Benefits:

BYK-W 969 is a monofunctional, deflocculating wetting and dispersing additive. It is particularly recommended for all filled PUR systems. Due to its OH functionality, this additive is incorporated into the polymer matrix and is therefore suitable for systems in which fogging and emissions are critical (e.g. automotive applications). BYK-W 969 is a wetting and dispersing additive for mineral-filled polyurethane and epoxy adhesives. It improves the wetting and dispersing speed of fillers during dispersion and reduces the viscosity to enable an increased filler content to be achieved.
