GENOMER* 3486 – for wood coating formulations

If you've been searching for the perfect UV oligomer for your wood coating formulations, then look no further. Whether you need a topcoat with a great appearance or a tough, resilient coating for demanding wear conditions RAHN's GENOMER* 3486 will provide the solution you are looking for.

There is a multitude of UV oligomer choices available to the formulator. Choosing the right one to use for your application can be a painstaking process. In addition to performance properties, other considerations such as cost, and bio-renewable content also play a role in final decision.

The good news is that RAHN has a versatile product that will make the choice much easier: GENOMER* 3486. This tetra-functional polyester acrylate provides toughness and resiliency without the higher cost normally associated with high performance oligomers. It offers excellent scratch and abrasion resistance, and its chemical resistant nature allows it to stand up to the harsh cleaning solutions on the market today.

In addition to its superior performance characteristics, the viscosity of GENOMER* 3486 is just 500 cP at room temperature making it ideal for coatings applied by roll coater or even spray or vacuum. Typically, a high performing oligomer would have to be reduced dramatically with monomer to achieve spray viscosity but with GENOMER* 3486, oligomer content can be maintained at a much higher level, making the most of the performance properties that this resin brings.

GENOMER* 3486 is also a good for wetting pigments and is compatible with inert gloss- and texture-control agents such as talc and silicas, making it an excellent choice for use in recoatable, sandable UV sealers and primers.

If you're looking to develop a new wood coating or improve an existing formula, GENOMER* 3486 provides a great foundation to build on. Give it a try!
